[Q] How to mount Ext3 formated USB Storage device ? - Asus Eee Pad Transformer Prime

Hello,
I promise I tried to find an answer before posting, but without success.
I can't mount a Ext3 USB device. Nothing happen. I tried with :
- VFAT => OK
- NTFS => OK
- Ext3 => NOK
- Ext4 => NOK
I don't believe that a Linux based Kernel was unable to manage Ext3 FS.
I also tried apps like "Drive Mount" and Mount Manager". Nothing.
I think it's a stupid thing I don't understand but ...
Others tests :
When I plug the USB device, in the kernel log (dmesg) I have :
usb-storage [...]
sda : sda1
[..]
VFS : Can't find a valid FAT filesystem on dev sda1
[...] Not an NTFS volume
It seems to be impossible but when I try :
dmesg | grep ext3
or
lsmod | grep ext3
I obtain nothing. Does the ext3 support is present in this kernel (2.6.39.4) ?
[UPDATE]
It seems that the kernel is ok, I have CONFIG_EXT<2,3,4>_FS to y in the /proc/config.gz
So, ... I really don't know I can't plug a Ext3 device
Note :
- Android 3.2.1 update to 4.0.3 : Same problem
- The system is rooted.
Thanks a lot !

A little Up

Hi SLEA_Bourges,
I got MK802 with android 4.0, I had the same problem like you, I tried searching and I bumped into your post, and later I found the solution, so here is what I did:
ssh into your android, I'm using SSHDroid
track your connected device by dmesg, mine was sda1.
then do:
mkdir /mnt/test/
mount -o loop /dev/block/sda1 /mnt/test/
ls /mnt/test/
Arena.mkv lost+found
you need to chmod /mnt/test/ so it can be readable from your browsers.

How to boot UrukDroid from internal flash disk on Archos 70IT (Update: Uruk 0.6)

Install Uruk 0.3 on second internal flash disk of Archos
UPDATE
At the last end of this guide you will find the steps necessary to upgrade to Uruk 0.6 from Uruk 0.3 or 0.4.
Near the end of this guide you will find the steps necessary to upgrade to Uruk 0.4.2 from Uruk 0.3 or to install it for the first time.
Please note.
If you are upgrading from Uruck 0.3 to 0.4.2 and installed google market hack before upgrade, after upgrade the market will be broken. To solve the problem reed the last step of this guide.
I've manage to boot from the second partition of the second internal flash of 8GB (/dev/block/mmcblk1p2) of my Archos 70IT Urukdroid vers 03 prepared by $aur0n on this post.
Thanks $aur0n for your awesome work.
It may work for other archos generation 8 too, except Archos 70 IT 250GB (i think that model doesn't have a second internal flash disk to boot from for SDE, but the owners can do it creating the 2 needed partitions on the HDD).
I've done it because:
- my micro sdcard is slow compared to internal flash
- i can mount correctly micro sdcard and second internal flash disc in Windows and linux by connecting Archos via USB and
- my sdcard is free. I can boot without sdcard in, take off from archos every time i want and upload files from a card reader or connecting the archos 70 via usb.
If you want to try it, be sure on what you are doing (linux knowledge is needed).
Try it on your own risk.
I don't have any responsibility if you brick your device (actually is hard to brick it following the guide, but pay attention please).
So if you are sure, read carefully this post and ask before if something is not clear enough for you.
I will try to answer as soon as possible (I'm actually a bit busy :-()
First of all install SDE, if you haven't already done (you can get information about it and download the SDE firmware from archos web page archos web page
Attention: Doing that You void your warranty...
Here the Archos notes:
Important notices to be acknowledged before downloading and installing the SDE firmware:
Once the SDE firmware is installed on a device, this device will be watermarked and ARCHOS will be able to detect that this firmware has been installed once.
Installing the SDE firmware is considered by ARCHOS as a voiding of the warranty and ARCHOS declines all liability and responsibility for any issues resulting from the installation of this SDE firmware.
ARCHOS strongly advises that only experts in embedded software development should install this firmware.
This firmware is provided "as is" and is not supported by ARCHOS.
Before following the steps required to install Uruk 0.3 some clarifications:
What you need to have:
- Archos 70 IT with terminal and SDE installed.
- Linux machine (nativly, visualized or LiveCD)
- Optionally Windows PC
Storage map of Archos 70 IT:
a) The first internal flash disk is of approximately 500MB (device /dev/block/mmcblk0) which is used by stock archos firmware and not changed by this guide.
Pay great attention playing with it, you may brick forever your Archos.
This flash disk have 4 partition and the block devices, mountpoints, filesystems type and size are as the following:
The first devices is "/dev/block/mmcblk0p1", mountpoint "/mnt/rawfs", type of filesystem "rawfs", size 32MB
The second devices is "/dev/block/mmcblk0p2", mountpoint "/mnt/system", type of filesystem "ext3", size 119MB
The third devices is "/dev/block/mmcblk0p3", mountpoint "/cache", type of filesystem "ext3", size 30MB
The fourth devices is "/dev/block/mmcblk0p4", mountpoint "/data" (mountpoint only by archos firmware), type of filesystem "ext3", size 300MB
b) The second internal flash disk is of approximately 7,5GB (device /dev/block/mmcblk1) which is used by this guide to boot SDE from and to accommodate the /data mountpoint (not any more on the "/dev/block/mmcblk0p4").
By stock archos firmware it has 1 partition (device /dev/block/mmcblk1p1), mountpoint "/mnt/storage", type of filesystem "fat32", size 7,5GB
After Uruk 0.3 installation it will have 3 partitions and the block devices, mountpoints, filesystems type and size will be as the following:
The first devices will be "/dev/block/mmcblk1p1", mountpoint "/mnt/storage", type of filesystem "fat32", size 5,5GB
The second devices will be "/dev/block/mmcblk1p2", mountpoint root "/", type of filesystem "ext4", size 500MB
The third devices will be "/dev/block/mmcblk1p3", mountpoint "/data", type of filesystem "ext4", size 1GB
C) The sdcard on device /dev/block/mmcblk2. On my case it have 1 partition (device /dev/block/mmcblk2p1), mountpoint "/mnt/storage/sdcard", type of filesystem "fat32".
Let's go:
The first step to do is to backup everything from your second internal flash disk (as above, it has 1 partition formated in fat32, 7,5GB capacity), just for backup purpose.
The simplest way is to connect your archos via usb to your linux box and copy directly that directory to a new directory on your linux with the default graphical file explorer of your distribution.
In my case it mounts automatically to /media/A70S (device is /dev/sdb1):
/dev/sdb1 on /media/A70S type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
Click to expand...
Click to collapse
If doesn't mount automatically in your case, find it using "dmesg" command on a terminal after connection complete and mount it manually.
Or you can copy it on your Windows PC (connect Archos via usb, drive mount automatically to A70S).
After backup, don't disconnect your Archos from linux. You have to resize the mounted Archos disk form 7,5GB to 5,5GB.
The easiest way is to do it graphically with your distribution partition manager utility.
First umount it by right click->umount, then resize it letting on the right side of the disk 1,5GB free space.
Create other 2 partition on that free space, first of 500MB and the other with the remaining space approx. 960MB.
Then apply the changes on the partition manager and you will have now 3 partition on the second internal flash disk of your Archos.
The first one with 5,5GB and formated on fat32, the second one 500MB not formated and the third partition of 960MB not formated.
On my case the devices are respectively /dev/sdb1, /dev/sdb2 and /dev/sdb3.
The next step is to format the second and third partition with ext4 filesystems without huge option (as from $aur0n post) on a linux terminal as root:
mkfs.ext4 -O ^huge_file /dev/sdb2
mkfs.ext4 -O ^huge_file /dev/sdb3
Click to expand...
Click to collapse
When finished, just remove safely archos from your linux box.
From the archos open a terminal and just type:
ls /dev/block/mmcblk1*
Click to expand...
Click to collapse
The result will be:
/dev/block/mmcblk1 /dev/block/mmcblk1p1 /dev/block/mmcblk1p2 /dev/block/mmcblk1p3
Click to expand...
Click to collapse
The second partition (/dev/block/mmcblk1p2) will be your new rootfs
and the third one (/dev/block/mmcblk1p3) your new application area (/data).
On this step you are going to copy all the staff on /data (device /dev/block/mmcblk0p4 mounted on /data)
to the third partition of the second internal flash (/dev/block/mmcblk1p3).
Mount the third partition first:
mkdir /tmp/data
mount /dev/block/mmcblk1p3 /tmp/data
Click to expand...
Click to collapse
and copy:
cp -rp /data/* /tmp/data
sync
umount /tmp/data
Click to expand...
Click to collapse
If you get any problems on coping (permissions) then the only way to do it correctly is to use "tar" to make a archive of data to a file on the first partition of the second internal flash disk (/dev/block/mmcblk1p1 mounted on /mnt/storage) like:
tar -cfvz /mnt/storage/data_app.tar.gz /data/
Click to expand...
Click to collapse
and then connect archos via usb to your linux computer (your three partition of the internal flash now will mount in automatic, let say /media/A70S, /media/disk1 and /media/disk2 from the devices /dev/sdb1, /dev/sdb2 and /dev/sdb3)
Now you have to extract the previous tar file (data_app.tar.gz) to the /media/disk2 (the third partition of archos internal flash disk mounted supposedly at /media/disk2):
cd /media/disk2
tar -zvxf /media/disk1/data_app.tar.gz
sync
umount /media/disk2
Click to expand...
Click to collapse
The next step, download the Uruk 0.3 version of rootfs (rootfs.tar.gz) from this link, and kernel image (zImage) from from this link on the /tmp directory of your linux box. I want to remember that this files are prepared and postet from $aur0n on this post.
If you are still connected via usb with your archos (if not, connect it),extract the rootfs (rootfs.tar.gz) directly on the mount point of the second flash partition (as above in my case is /dev/sdb2 mounted on /media/disk1) on linux:
cd /media/disk1
tar -zvxf /tmp/rootfs.tar.gz
Click to expand...
Click to collapse
Change the following lines of the init.rc file (mount point of root filesystem):
mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid
# Uncomment this
# mount ext4 /dev/block/mmcblk2p2 /data noatime
with those:
#mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid
# Uncomment this
mount ext4 /dev/block/mmcblk1p3 /data noatime
Change the line on the file/media/disk1/syste/etc/vold.fsatb:
#dev_mount_lun volume_sdcard /mnt/storage/sdcard 3 /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2p3
with that:
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
sync
umount /media/disk1
Click to expand...
Click to collapse
and remove safely archos from the linux box and shutdown Archos.
Download the initramfs.cpio.gz_Uruk_0.3.zip from here (or from the attachment on the end of this post) and unzip it on the /tmp folder of you linux box.
Flash the initramfs.cpio.gz and zImage (remember , you downloaded zImage on the step 4 and placed it already on /tmp) on SDE environment doing:
- While power on your archos, press the "Volume -" button
- Go to "Recovery System",then "Developer Edition Menu"
- Select "Flash kernel and Initramfs".
- Attach your Archos via USB to linux computer. Archos will automatically mount, in my case is A70S_REC mounted on /media/A70S_REC/. Copy the files (initramfs.cpio.gz and zImage) from /tmp folder.
cp initramfs.cpio.gz zImage /media/A70S_REC/
Click to expand...
Click to collapse
Disconnect safely archos, then push "Ok", power and the archos will reboot.
- Press the "Volume -" to boot to the ""Boot Menu" and choose "Developer Edition" or just while booting press both "Volume -" and "Volume +" to boot directly to the "Developer Edition".
You are done.
Enjoy booting from internal flash (SDE edition).
Update: Uruk 0.4.2
There are 2 possibilities:
- You want to upgrade from Uruk 0.3
- Install Uruk 0.4.2 for the first time (You are on stock archos firmware).
Let's begin with the upgrade from Uruk 0.3 to Uruk 0.4.2
First of all download the Uruk 0.4.2 rootfs prepared from $aur0n UrukDroid-0.4.2-rootfs.rar on your linux box.
Download also UrukDroid-0.4.2-kernel.rar from here (or from the attachment on the end of this guide).
It's is $aur0n's one with the modifications to boot and mount /data from second internal flash.
Copy the above 2 files on the folder /tmp/archos of your linux machine. In my case is the 2 downloaded files are
under /home/shklifo/Download folder:
mkdir /tmp/archos
cd /tmp/archos
cp /home/shklifo/Download/UrukDroid-0.4.2-kernel.rar /home/shklifo/Download/UrukDroid-0.4.2-rootfs.rar .
Click to expand...
Click to collapse
Unrar both of them (if you don't have rar utility, just install it), giving the command:
rar x UrukDroid-0.4.2-kernel.rar
rar x UrukDroid-0.4.2-rootfs.rar
Click to expand...
Click to collapse
When the unrar process goes ok you will see the following on terminal (example of UrukDroid-0.4.2-kernel.rar):
[email protected]:/tmp/archos# rar x UrukDroid-0.4.2-kernel.rar

Click to expand...
Click to collapse
You are upgrading and you have all the applications on second internal flash disk already, so just remove the UrukDroid-copy_data.cmd, you don't need it:
rm UrukDroid-copy_data.cmd
Click to expand...
Click to collapse
Now you have to copy UrukDroid-rootfs-upgrade.tgz to the rootfs of the archos (second partition of the second internal flash disk mounted on / of type ext4 with 500MB space).
To do that just connect archos via usb to your linux box and all the tree partition of archos second internal flash will be mounted automatically.
To verify where those partition are mounted just type:
mount
Click to expand...
Click to collapse
on a linux terminal and on my case is as following:
[email protected]:/tmp/archos# mount
...
/dev/sdb1 on /media/A70S type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
/dev/sdb2 on /media/disk type ext4 (rw,nosuid,nodev,uhelper=hal)
/dev/sdb3 on /media/disk-1 type ext4 (rw,nosuid,nodev,uhelper=hal)
/dev/sdc1 on /media/disk-2 type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
Click to expand...
Click to collapse
and "df -m" like:
[email protected]:/tmp/archos# df -m
/dev/sdb1 5622 2897 2725 52% /media/A70S
/dev/sdb2 485 244 216 53% /media/disk
/dev/sdb3 973 268 656 29% /media/disk-1
/dev/sdc1 15266 1157 14110 8% /media/disk-2
Click to expand...
Click to collapse
So in my case the second partition of the second internal archos flash disk of 485MB is:
/dev/sdb2 485 244 216 53% /media/disk
Click to expand...
Click to collapse
mounted on /media/disk
Then just copy the UrukDroid-rootfs-upgrade.tgz file on the second partition of the second internal archos flash disk, like in my case:
cp /tmp/archos/UrukDroid-rootfs-upgrade.tgz /media/disk/
Click to expand...
Click to collapse
Safely disconect archos from the linux box and shutdown completely your archos.
Now you have to flash initramfs (initramfs.cpio.gz) and kernel (zImage) to your archos from "Recovery Menu" (you know already how to do it),
or if you forget it just do the following:
- While power on your archos, press the "Volume -" button
- Go to "Recovery System",then "Developer Edition Menu"
- Select "Flash kernel and Initramfs".
- Attach your Archos via USB to linux computer. Archos will automatically mount, in my case is A70S_REC mounted on /media/A70S_REC/. Copy the files (initramfs.cpio.gz and zImage) from /tmp/archos folder.
cp initramfs.cpio.gz zImage /media/A70S_REC/
Click to expand...
Click to collapse
Disconnect safely archos, then push "Ok", power and the archos will reboot.
- Press the "Volume -" to boot to the ""Boot Menu" and choose "Developer Edition" or just while booting press both "Volume -" and "Volume +" to boot directly to the "Developer Edition".
You will see the UruckDroid 0.4 screen with "Initramfs: Loading ...." than Rootfs: Loading .... and finally you will see the Uruck Desktop.
Enjoy
Install Uruk 0.4.2 for the first time
For those who whant to install Uruk 0.4.2 for the first time (now it's simplier that Uruk 0.3) will do:
a) First backup, create the partitions and filesystems on the second internal flash disk of archos (step 1
and step 2 of the Uruk 0.3).
You don't need anymore step 3 (copy of /data folder), because Uruk 0.4.2 do it automatically.
b) Then following step by step the guide Let begin with the upgrade from Uruk 0.3 to Uruk 0.4.2, except removing UrukDroid-copy_data.cmd file, because you need it to copy automatically /data files.
When you are on the step "copy the UrukDroid-rootfs-upgrade.tgz file on the second partition of the second internal archos flash disk", you need to copy additionaly UrukDroid-copy_data.cmd like:
cp /tmp/archos/UrukDroid-rootfs-upgrade.tgz /media/disk/
cp /tmp/archos/UrukDroid-copy_data.cmd /media/disk/
Click to expand...
Click to collapse
Than follow till the end the guide Let begin with the upgrade from Uruk 0.3 to Uruk 0.4.2.
Enjoy
OPTIONAL: Install google market.
If you have already istalled google market (using gAppsInstaller for example), you have to uninstall it (market/vending) first.
Then download UrukDroid-0.4.2-GoogleMarket.zip and copy it on the root (/) filesystem of archos (see above on the upgrade section an do the same steps of copying UrukDroid-rootfs-upgrade.tgz to archos rootfs).
Reboot archos.
NOTE
If you are upgrading from 0.3 version to 0.4.2 and installed before the google market from kenyu73 like i did, then the market will be broken and doesn't work any more.
To get it back, you have to remove all the google applications from SDE (Uruk 0.4.2) including the kenyu73's installer (gAppsInstaller).
Then install the market as on the previuos step OPTIONAL: Install google market downloading the file UrukDroid-0.4.2-GoogleMarket.zip and following the instructions.
After rebooting archos on SDE, you need to fix it, because you can't access the whole market (missing some "protected applications" like copilot etc).
To fix just do the following steps as kenyu73 explain on his post :
Go to Settings-->Manage Applications-->All-->Market (Clear Cache then 'Force Stop', DO NOT clear data).
Setting-->Manage Applications-->All-->Google Services Framework (Clear data then 'Force Stop').
Reboot.
Click to expand...
Click to collapse
I've done it twice the fix step, and after that no problem anymore. All the google applications (downloaded from the fresh working market) are working correctly as before.
Update: How to upgrade to Uruk 0.6 from Uruk 0.3 or 0.4.2
There are 2 possibilities:
a) The first one is the simplest one.
Just download the $auron Uruk 0.6 UrukDroid_0.6-EasyInstall.rar posted on this post, extract it on your computer and delete the file initramfs.cpio.gz, because we don't need it.
Then download the file initramfs.cpio_Uruk_0.6.gz.rar in attachment on the end of this post and extract it on the same directory of your computer (this is the initramfs that you will flash on SDE prepared from $auron and can be found on the /root/ directory of $auron new rootfs UrukDroid-install.tgz).
Then boot Archos on stock Android and connect it to your linux box via USB. The root filesystem of Archos (/dev/block/mmcblk1p2 on Archos) will be mounted on some directory on linux automatically, just find it or manually mount it (it's the filesystem with 500MB space, to be sure just type "df -h" on a terminal).
With root on a linux terminal go to that directory (in my case was /media/Disk-1) and remove all the files there:
Code:
rm -rf *
Then copy the UrukDroid-install.tgz extracted before from UrukDroid_0.6-EasyInstall.rar on the above directory.
So, you will have only the file UrukDroid-install.tgz on your rootfs directory of Uruk.
Then disconect safely Archos from your linux box and flash initramfs.cpio.gz and zImage files on SDE (you know how to do that ...) and boot to SDE.
That is
Uruk 0.6 will automatically copy everything needed as you will see on the boot time.
You have to do a last thing to be able to mount automatically the sdcard on Uruk 6. Uncomment the sdcard line on the file /system/etc/vold.fsatb like:
Code:
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
This is needed on the second method too (the one below).
Who want to install Uruk (version 0.6 in this case) for the first time on internal, must create and format the 2 partitions of the second internal flash disk (like on the beginning of this post described) and follow step by step the above method and at the end copy everything from the data partiotion (last partition of the first internal flash /dev/block/mmcblk0p4) to the third partition of the second flash disk (/dev/block/mmcblk1p3).
b) The second method is more complicated, but works also good.
You just install Uruk 0.6 to a sdcard like on this $auron post, than shutdown Archos, put the microsd card on a card reader connected to a linux PC and with root make a tar archive of the entire rootfs (root filesystem) of Uruk 0.6 (the second partition of the sdcard with 500MB of space on ext4 filesystem) to a tar file that you can put to the first partition of the sdcard (the fat partition of the sdcard).
Eject the sdcard and put on Archos. Turn on Archos and from a terminal on Uruk as root mount the second partition of the flash disk (/dev/block/mmcblk1p2) on a directory and just delete ("rm -rf") everything on there and then extract the tar archive there.
So, you just put everything from rootfs of the sdcard to internal flash, with correct permissions, timestamp, ownership etc.
Now just shudown Archos, take off the sdcard and boot.
This time it will Uruk 0.6 will boot from internal flash
Enjoy it
I wish I could understand more clearly how to do this with a fresh install...
This is what I am looking to do, using it on internal... but this might be a little too complicated for me.
What about 101?
Does this method applicable to Archos 101 model too?
If someone already have been tried it on 101, please reply with details here, if any troubles you have after installation or any changes need to be done.
Also I am curious about does anyone have tried to connect USB thumb drive to the tablet with modified rom and root access? Do we still have any issues with USB drive recognition?
Is this applicable for UrukDroid 4.1 and The Archos IT 35?
well great work but i dont know if i get it to work and Im a little bit confused -
is it writable in windows per media player (mtp) or per explorer or both (with ext-x driver)?

Why not. The 101 model have the second internal flash (8 or 16GB) as the 70 S model have. To be sure just type mount and df -m on a terminal in Archos device and you will see the flash drive (/dev/block/mmcblk1p1) formated in fat32 and mounted on /mnt/storage.
I only changed the mounting point on the file init, init.rc and /system/etc/vold.fstab from $aur0n files to be able to boot SDE from the second internal flash disk and doesn't change anything else, configuration file of specific model included.

I'm still excpecting my host cable from Hong-Kong and can't try that, but i think will not be a problem.
good work

I do not own your device (it is a Archos 32 IT?), but if is that model, it got a 8GB internal flash like archos 70 IT. The firmware is the same for all archos generation 8 devices (with same configuration files change), but i haven't change them (and $aur0n too i think, but he can answer himself).
So just try it, if you have no problem of understanding all the steps on the first post. You can't break anything. And if it will not work (worse case) or have other problems you just have SDE installed (you can remove it if you want) and 2 more partition on the internal flash disk with some files on them.
You can just delete the partitions and risize (increment) the first partition as from stock. In all situation we are able to boot to stock firmware.
I only change the mountpoints as i wrote in the previous posts on the files init, init.rc and vold.fstab from uruk 0.3.
So mine and $auron solution changed only on the boot partition (mine is booting form the second partition of the internal flash disk, him from the second partition of sdcard) and the application data partition (mine on the third partition of the internal the flash, him on the third partition of the sdcard). All the other files are from him (thanks $aur0n).
I've not installed yet the 0.4.1, i got little free time actually and of the market problem (if i install the 0.4.1, i must uninstall the market on stock firmware and will be not able to access it from original/stock firmware).
But if i decide to install it, i will report here.

Thanks, as i say above you don't loose anything trying to install it, only time
So, if i understand well your question, on my archos i'm able to access the first partition of the flash disk (it's a fat32 as from stock, only risezed in 5,5 GB) on my windows XP PC by usb connection to archos.
The second (boot partition 500MB) and the third (data application area of 1GB) partitions of internal flash disk are ext4 formated (stock ext3) and can't be mount on a windows PC, and for me have any sense mounting them on a PC.
The sdcard is accesible via usb connection (archos to PC) or via card reader. If you format it fat32 is in r/w mode (as i've done), ext3 or ext4 in readonly mode i think (not yet tried), because actually isn't out a driver to be able to write a linux partition on Windows.
From Ubuntu (connecting archos via usb) i can mount all in r/w mode (all the 3 partitions of the internal flash disk and sdcard too).
Later i will post some picture/command output (mount,ls) from Ubuntu.
In attachment a picture of the flash disk (A70S E: ) and sdcard (Disco rimovibile F: ) on my Windows XP macchine.

Just a suggestion.. Please be consistent with your instructions, 1 step your instructions are for linux and the next step would be for archos.
It's really hard to follow what needs to be done or how it should be done properly, considering you're messing around with the internal storage there's bigger chance of bricking your device.
I appreciate all your hard work and contributions here, it's just that it's not that user friendly.

Just to be clear, from archos terminal you have to do only 1 thing, copy or tar the "/data" mountpoint/directory, because this is the 4-th partition of the first internal flash disk (/dev/block/mmcblk0p4) and it can't be mounted on linux via usb connection.
All the other steps are from linux (the first step, you can do it from Windows too).

There are 2 internal flash disk in Archos, /dev/block/mmcblk0 of 500MB (used by archos architecture and nobody is touching this flash disk, it's dangerous and you may brick your device) and /dev/block/mmcblk1 of 8GB which is used by the this guide to boot SDE from. So, if you are able to understand what you are doing and don't touch the first flash disk, than nothing can happens.

With that i'm in line with your thoughs, thanks. I will try to do it more simple and understandable.
I've followed all the instructions exactly. I'm good with linux, so it wasn't very hard, but when I booted into the Developer Edition at the end, I was at the Initial Setup Screen, like it didn't mount the /data partition. Also, I can't get ES to show the file system, so it doesn't seem to be rooted. Any ideas what's going on?
EDIT: You have a typo in the init.rc the change should be to mmcblk1p3, not mmcblk1p2.
EDIT: Another typo: "dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk1" should be mmcblk2, not 1.
Now my data is there, and I can mount SD cards, but I still can't connect to a computer with a USB cable.
EDIT: All Fixed. I flashed a new kernel from http://forum.xda-developers.com/showthread.php?t=897877 and now have USB Storage working. I used the zImage from ardatdat's kernel with your initramfs.cpio.gz and the changes I listed above. Everything seems to work perfectly, and it's way faster than it was before. I was using Ardatdat's full kernel and booting from internal memory before. When I rotated the screen it used to take almost 10 seconds to update all the icons on the home screen. Now it takes less than 2-3 seconds to update. Great work on the EXT4 conversion! If you'll permit me, I'm going to write up a guide that incorporates my experience, and of course give you full credit.
Update: Just updated to UrukDroid 0.4.1. Needed a little more customization, but usb storage worked with the default 0.4.1 kernel instead of needing ardatdat's kernel. Currently testing to see which is better. Uruk says it's kernel has usb charging enabled, a very exciting possibility, but I kind of doubt it works on the A101IT.

Thanks for the corrections (you pay the needed attention), but i just modified the first post radically (easier).
Sure, you can do your own thread with your experience on the installation.
I will install Uruk 0.4.1 too, and update the first post.
WORKING
I had to add a new line into the init.rc file, but afterwards I was able to get Uruk 0.4.1 to boot internal
***mount ext4 /dev/block/mmcblk1p2 / noatime*** - I don't htink you have this in your steps...
After I did this, it works. I also am able to see both the internal and external storage in windows.
I didn't know if you need that line or it was left out of your steps process. All I did to get this to work on an existing 0.4.1 was:
1. Move the data off the internal inside windows to a saved directory on my PC.
2. Partition the 3 partitions like you describe on the internal and formated as you describe...
3. Mount the partitions inside my VMplayer Ubuntu sdb2, sdb3, sdc2, and sdc3 (sdb was the internal formated like you describe and sdc was my 16 0.4.1 SD card fromatted using uruk already)
Su terminal CODE:
$su
***password
#
#cd
#cd /tmp
#mkdir sdb2
#mkdir sdb3
#mkdir sdc2
#mkdir sdc3
#mount /dev/sdb2 /tmp/sdb2
#mount /dev/sdb2 /tmp/sdb3
#mount /dev/sdb2 /tmp/sdc2
#mount /dev/sdb2 /tmp/sdc3
4. Copy through terminal everything from sdc2 --> sdb2 using below code and Copy through terminal everything from sdc3 --> sdb3 using below code
**CODE I used:
#cp -rp /tmp/sdc2/* /tmp/sdb2
#sync
#cp -rp /tmp/sdc3/* /tmp/sdb3
#sync
6. Add in the lines inti init.rc to mount the sdb2, and the sdb3 instead of sdc2 and sdc3
mount ext4 /dev/block/mmcblk1p2 / noatime
mount ext4 /dev/block/mmcblk1p3 /data noatime
7. Add the line into tmp/sdb2/system/etc/vold.fsatb (Which is where I mounted that..)
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
**I believe in 0.4.1 it is already like this, so i really made no changes to vold.fsatb....***
Unmounted all 4 I had mounted into /tmp using terminal ubuntu
CODE (I was already inside cd /tmp/sdb2 and i had edited the init.rc and saved it):
#sync
#cd..
#umount /tmp/sdb2
#umount /tmp/sdb3
#umount /tmp/sdc2
#umount /tmp/sdc3
EDIT: after this step, you will need to mount the Archos back into Windows, and copy the files you saved into a folder on your windows PC back into the Internal Fat32 storage. This was why you backed it up in the first place.... You might have to reboot and boot into your stock OS to get the internal to mount back into Windows, i did...
Reboot and go into the developer menu
Reflashed your initramfs and Uruk 0.4.1 Zimage and booted to developers edition...
***Remember this will only work if you have a preexisting 0.4.1 on an SD card where it is formatted with #1 fat32 for dtorage #2 500Mb and #3 1G and it already has been working using $auron's method.
BIG thanks to $aron and shklifo and msticninja... I am very happy using my internal memory to boot with instead of the SD card. i will prob keep the SD card I have and use it whenever I need to boot to SD and just get a different one for Videos and Music.

I really appreciate your feedback.
But you don't need to add the line:
Code:
mount ext4 /dev/block/mmcblk1p2 / noatime
on the file init.rc, because it is present on the init file included on initramfs.cpio.gz.
If you extract the initramfs.cpio.gz attached on my first post with this command on a shell:
Code:
gunzip initramfs.cpio.gz && cpio -i -d -H newc -F initramfs.cpio --no-absolute-filename
You will find the following line:
Code:
$MOUNT -t ext4 -o noatime,errors=continue /dev/mmcblk1p2 /new-root
To upgrade to $aur0n 0.4.2 now it's really simple.
I'm preparing the new initramfs.cpio.gz. And putting the new rootfs of 0.4.2 on the rootfs of our archos (just to remember it is on the second partition of the second internal disk on device /dev/block/mmcblk1p2 mountet on /) and flashing the new initramfs.cpio.gz and zimage, when booting up on "Developer Edition" it will upgrade automatically.
Is there a reason why we want to be on 0.4.2?
I am not having problems with Market, is there other benifits of this update?
JW
BTW: Thanks for this halp on getting to internal.. I am not sure why we wanted to not do this in the first place.. I guess because some SD cards are faster, mine is working pretty fast and I think the internal is at least class 6

Just see on the $aur0n post about the new version log change. We will have upgraded module, new wifi, more services like samba sshd etc.
I to havn't any speed problem with internal flash. It is fast enough (with dd copying speed test got till 16 mbit/s write speed) on the internal flash and it is way faster than my sdcard class 4.
0.4.2
Well.. I already reverted back to the origional wifi config file using terminal, and my Market is good to go.
I'm not sure that there are any major differences between 0.4.1 --> 0.4.2
If I am wrong, i think it requires to uninstall all google apps to make that upgrade, which I don't think I need to do.
Am I wrong?

From $auron post on Uruk doesn't seem to be difference between 0.4.1 and 0.4.2, except google applications. With the 0.4.2 you can install the google staff separatly with UrukDroid-0.4.2-GoogleMarket.rar. If you have those apps allready on your 0.4.1 than nothing change, you don't need to upgrade.
Thanks and no problem with your methods.
My 16GB microSD card isn't very good and boot / use of archos 101 is very slow with Uruk0.4.2 installed on external SD.
Now it's fast installed on internal SD...
Maybe this help:
if can't mount ext4 partition on your linux box, you can do:
tune2fs -E test_fs /dev/sdbx (sdb2 for instance)
and then:
mount -t ext4dev /dev/sdbx /mnt/sdcard
trouble with fresh install for 0.4.2 $auron....
I was able to create 3 partition internally (sdb1(vfat), sdb2(ext4), sdb3(ext4))
I was able to move rootfs and cmd script to sdb2
I was able to flash initramfs and zImage
But I'm stuck when rebooting into SDE (the screen is all messed up)
Any suggestion?
I didn't modify init.rc and vold.stab since this is a fresh install

Does this method applicable to Archos 101 model too?
If someone already have been tried it on 101, please reply with details here, if any troubles you have after installation or any changes need to be done.
Also I am curious about does anyone have tried to connect USB thumb drive to the tablet with modified rom and root access? Do we still have any issues with USB drive recognition?

Yes this procedure works the same way on the A101. I have the 16GB version so I made the 1st partition a bit bigger but that was the only deviation.

[Q] How to mount a USB NTFS Harddrive?

I still can not get an external usb ntfs drive to mount... I have tried Robeet's suggestion of:
NTFS mounting requires these commands, in terminal:
su
mount -t ntfs /dev/block/sda1 /mnt/usbdisk
Problem is that you are mounting as root, so you can't see the mounted files in the Android GUI. You could also do a chmod, but that's a bit of an extra burden. Anyone know how to mount this as a UID that it viewable in the GUI?
EDIT: This should work:
su
mount -o umask=000 -t ntfs /dev/block/sda1 /mnt/usbdisk
and this does not work... keeps saying no such device. I am running the ZPAD Clean 3.0 Rom and the latest kernel from Pershoot...
Anyone else having success getting a WD external usb hard drive to mount?
do a search this was solved required smaller partitions and reformat .
I make the NTFS USB external HDD with its own power supply work finnaly with the help of rajeevvp's article:
Thread: Mounting 2 storage usb devices View Single Post #8 20th May 2011, 05:01 PM
rajeevvp Senior Member Join Date: Aug 2010 Location: Bangalore Posts: 563
(I lost his link.)
The main rajeevvp's idea is to download the right version of ntfs.ko
"For this, you have to know which kernel you're running. There are 2 kernels that are commonly used on the gTablet: clemsyn's and pershoot's. I use pershoot's kernel so my instructions will be for that. The pershoot kernel supports NTFS filesystems, but, this support is not built into the kernel. Support is instead provided using kernel modules which you'll have to download first from the author's website and then load manually.
Download the correct kernel modules file for the running kernel. Find the kernel version first:
Code:
$ uname -a
Linux localhost 2.6.32.40-cyanogenmod #1 SMP PREEMPT Fri May 13 17:37:53 EDT 2011 armv7l GNU/LinuxThe kernel version is 2.6.32.40."
Go to http://droidbasement.com/db-blog/ and download the kernel modules file for that kernel version
Then
Load the kernel modules (I'm assuming now that they're on /mnt/sdcard), then mount the HDD:
Code:
$ su
# insmod /mnt/sdcard/nls_utf8.ko
# insmod /mnt/sdcard/ntfs.ko
# mount -o umask=000 -t ntfs /dev/block/sda1/mnt/usbdisk (from Roebeet)
To unmount it
Code:
$ su
# umount /mnt/usbdisk
I use GScript lite to do the work. I can play large video file from /mnt/usbdisk (NTFS USB HDD)
Thank you very much Rajeevvp for your guide.
Hope that help.

filesystem mounting / repartitioning on live android system

Hy!
I have a mi2s and this phone is come to separated partitions in its internal drive. It has separated data and sdcard partition. My sdcard partition not mounted for some reason.
I want to keep this partition system, I just want to either mount the sdcard partition, or resize them without loseing data. (I can delete the sdcard partition but I want the data partition untouched, I had a long fight till this rom started to work with google play store, and I dont really want to remach it after all my apps are installed... Fun thing that after the first boot both partitions were mounted, after my first reboot only the data.)
I tried:
adb mount - adb sees it Android not sees it
write it to the fstab.qalcom - its on the / if I reboot the phone its loaded from somewhere again (I know its a ramdisk), my modifications are not permanent on there
I have basic linux knowlage and I started to dig into it, but I cant google out a general solution.
My questions:
How can I mount a fs like the usb otg from adb/android shell?
Can I edit the fstab file in its permanent store on an installed rooted device? And if I can where?
If I place new lines to the fstab on rootfs how can I tell the system to "reload" it?
Can I extend an ext4 partition from adb without loseing its data? *
* I have the required tools like parted from xiaomi forum, I cant post the link but you can google it with "Mi2S extending size of storage partition stillka".
Any help appreciated, and sorry for my english I'm not native.
So the basics:
If you can mount it from adb its a half win!
Try search the correct block partition and mount it with -t, add the correct file system and don't try auto it.
After you can mount it, you need to start an sdcard process its in /system/bin/sdcard. I had to see the custom rom implementation for that, in cm u need to param it "sdcard from to 1023 1023", but in samsung devices the to is hardcoded, and you nedd to do some sed magic.
After that your android programs will see it as a valid sdcard partition.
The harder way:
Wrap it to a startup script.
Add this script somewhere to run at bootup.
I'm still working on it, but I'm closer and closer. After I have the final solution I will write here once more.
I get so much help from there:
http://forum.xda-developers.com/showthread.php?t=2467048
If somebody want to do this:
After few hours of trying to mount the filessystem in boottime (in CM 12.1 its a hard work), i gave up, and went to a repartitioning way.
BE CAREFUL YOU CAN BRICK YOUR DEVICE IF YOU HAVE NO IDEA WHAT IM TALKING ABOUT!
I merged 2 tutorials:
reboot phone into CWM, connect phone to PC
connect to phone over adb and check if you are root
mount system
umount cache
umount data
copy content of partition_tools.zip into /system/bin and add executable attributes if necessary
Run parted on your device: parted /dev/sdX
Change display unit to sectors: unit s
Print current partition table and note the start sector for your partition: p
Delete your partition (won't delete the data or filesystem): rm <number>
Delete your partition (the second one we will delete data from there): rm <number>
Recreate the partition with the starting sector from above: mkpart primary <start> <end>
Recreate partition 27 (the last) mkpartfs primary ext2 3070 15758
name 26 userdata #we have to set back partition labels
name 27 storage
Exit parted: quit
Check the filesystem of 26: sudo e2fsck -f /dev/sdXX
Resize filesystem 26: sudo resize2fs /dev/sdXX
restore partition 27 with:
tune2fs -j /dev/block/mmcblk0p27
e2fsck -fDp /dev/block/mmcblk0p27
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p27
e2fsck -fDp /dev/block/mmcblk0p27
Of course in parted print you can see your original partition layout and this case it is possible that you have other partition numbers (my 26 partition is labeld by userdata and 27 with storage, and I gave more space to userdata from storage without loseing any data from userdata).
You can download the partition_tools.zip from the original miui forum, try to search to mi2s extending size of storage partition. (yes it will work with other devices too)

How to mount ext4 formatted MicroSD card on Android 6.0?

Hi
my phone is lg k10 android 6.0 and rooted
for me only mounted fat32
when I formatted ext4 microsdcard and insert on phone show message "can't use sd card. tap to set up for use"
when click this message my microsdcard formatted fat32.
How to mount ext4 formatted MicroSD card on Android 6.0?
Thanks
So you need ext4 for symlinking purposes eh?
Anyway , if your device supports ext4 , depends on vendor , you can try to mount it manually
Root is required.
In adb ,
Code:
-adb shell
-su
-df
- cat /proc/partitions
when you know the partition for your external sd ,
Code:
mount -o bind "path to partition" /storage/sdcard1
If this works , you want to add this as a script to run at boot or create a init.d script by your own and give it 0755 permission.
Cheers
-Edit
If it didnt work , try this , it may be a little complicated

I need you to be particular with your wordings ..
Do you need ext4 sdcard to be mounted or exfat?
PS:
For File Size larger than 4gb , you can try NTFS , It is supported natively by my device.
Try formatting sdcard as NTFS and then insert into device.
If it shows any problem or doesnt mount , try this
Code:
-su
-ntfs-3g /dev/block/mmcblk1p1 /mnt/sdcard/external_sd
-vold
If this works , try making an init.d script with the above code , to mount sdcard everytime at boot

not work show message again
"mount: Not a directory"
I use terminal for commands
I guess due to marshmallow's strict policies , you are not being able to mount NTFS,
I will suggest you to format card as ext4 using EaseUS Partition Manager and then insert sdcard in your device.
Ext4 is natively supported by linux and I dont think it should cause you problems.
Cheers , Pressing that Thanks button wont harm you
I don't know lg k10 android 6.0 not support formats exfat,ntfs,ext4 for micro sdcard.
Does anyone else have a comment to fix the problem?

Gonna try this.
akash14darshan said:
So you need ext4 for symlinking purposes eh?
Anyway , if your device supports ext4 , depends on vendor , you can try to mount it manually
Root is required.
In adb ,
Code:
-adb shell
-su
-df
- cat /proc/partitions
when you know the partition for your external sd ,
Code:
mount -o bind "path to partition" /storage/sdcard1
If this works , you want to add this as a script to run at boot or create a init.d script by your own and give it 0755 permission.
Cheers
-Edit
If it didnt work , try this , it may be a little complicated

Mounting F2FS SDCard

Hi, i formatted my sdcard to f2fs and it can be mounted on custom rom i previously use, PixelExtended by changing <type> from vfat to auto in fstab.qcom. Yesterday, i moved to AOSP Kraken and did the same modification to fstab.qcom but sdcard still can't be mounted (unsupported). Is there anything i can do to make my current rom able to mount f2fs sdcard? Maybe like replacing the files or anything using the files from previous rom that is responsible to mounting sdcard?
NB : My device is Redmi Note 9 Pro (joyeuse). Im using same custom kernel in both rom
I have same problem here

@namhoang235
Its possible to mount f2fs/ext4 microSD / usb-otg on android.
i use f2fs since 2017 for microSD on Android.
u need to be rooted, and, a your need to have kernel f2fs-support.
if you can format /data as f2fs and mount it.
then, youtl already have f2fs support.
else you can use any custom kernel with f2fs support.
as (on 2018) for my asus x00td device, i requested @Sakhtlonda69 to add f2fs support in his custom kernel build.
(and, he did it!)
----
these are few values , which u need to know, to execute the below commands
# YOUR_DEVICE_NUMBER = the exact partition which is your memory card's 1st partition.
# If you have a device with UFS storage (not eMMC), then, microSD will be most likely at "mmcblk0p1"
# If you have a device with eMMC Storage (not UFS), then, microSD will be most likely at "mmcblk1p1"
# If you still can't understand what I'm saying,
# Make sure your memory card is inserted,
# then,
# just go to /dev/block from any rooted file manager
# search "mmcblk1" there.
# if it only shows these 2 files: mmcblk1 and mmcblk1p1
# then, "YOUR_DEVICE_NUMBER" is "mmcblk1p1"
but, if you can't find anything with "mmcblk1"
#then, search "mmcblk0" there.
# if it only shows these 2 files: mmcblk0 and mmcblk0p1
# then, "YOUR_DEVICE_NUMBER" is "mmcblk0p1"
so, "YOUR_DEVICE_NUMBER" is actually either "mmcblk0p1" or "mmcblk1p1"
WARNING: (If you format any wrong system's internal storages partition, your device will most likely be bricked!)
Understand?
---
#---Format your microSD part with f2fs---#
simply unmount the memory card from Settings > Storage.
then, launch Terminal Emulator/ Termux App
(make sure you have root)
enter below 2 commands one by one:
su
make_f2fs -f /dev/block/YOUR_DEVICE_NUMBER
#---Formated successfully---#
-----
Now reboot your device
After reboot your device show a notification that your Memory Card is corrupted!
(because most of the android system can't mount anything except fat/exFAT for Memory Card - it's normal)
---
to mount the microSD (Memory Card),
Launch Terminal/Termux: and, enter below lines one by one:
(YOU NEED TO ENTER THESE LINES EVERY TIME AFTER YOU REBOOT YOUR DEVICE)
su
mkdir -p /mnt/extsd
mkdir -p /sdcard/_MemoryCard_
# Mount f2fs-microSD at /mnt/extsd
mount -t f2fs -o rw,nosuid,nodev,noatime,noexec,discard,fsync_mode=nobarrier /dev/block/platform/soc/*.sdhci/mmcblk*p1 /mnt/extsd
# Bind using sdcardfs f2fs-microSD from /mnt/extsd to /sdcard/_MemoryCard_
mount -t sdcardfs -o rw,nosuid,nodev,noatime,noexec,fsuid=1023,fsgid=1023,gid=9997,mask=2 /mnt/microSD /mnt/runtime/default/emulated/0/_MemoryCard_
----
Now,
microSD is mounted under Internal Storage's _MemoryCard_ folder.
---------
(Extra things)
If you dont want to show Memory Card Corrupted (annoying) Notification on each boot,
simply edit your /vendor/etc/fstab* file.
(it will be under : /vendor/etc/fstab.qcom or /vendor/etc/fstab.default or /vendor/etc/fstab.emmc)
(if you have more that one fstab, edit all)
Edit fstab* :
Find the line contains
"/devices/platform/soc/ ......... /mmc_host*"
add a "#" at the starting of that line (without quotation marks)
and save that file.
Reboot your device.
Now, It won't show any corruption device notification.
