When i woke up this morning i had to hold powerbutton for, is it 10 seconds, to restart the phone. When it booted up again i got a message that said somethings wrong with the sdcard, and it asked if i wanted to format. Hell no! I got things there i really want to keep (yea stupid of me not to have it backed up!).
I went in to recovery and if i enter the "install zip from internal sdcard" i can see the card and all it's files.
If this would have happened to my external sdcard i'd just put it in my laptop doing a scandisc and all would be cool.
Now it isn't. So how do i solve this?

Have you tried to mount the internal SD to the PC over USB from from recovery mode, using the "mounts and storage" menu?
Considering you have CWM recovery running, if not flash a kernel with CWM and try it then.

Hi and thanks for answer!
Yes i have CWM, just forgot to mention it.
I just tried to mount usb storage from cwm and both cards shows up, but only external can get accessed. Nothing(!) happends when i pick the scandisc option and clicks start. Just doesnt start.
Edit: still can SEE the files in cwm, just need to know how to copy them to a safe place so i can format the sd. :/

Hm, in that case you could copy them via an adb shell over to the external card.
adb is a command line tool that's part of the Android SDK.
Invoke a shell via
Code:
adb shell
when the phone is in CWM recovery and connected via USB.
Make sure internal and external SD are mounted (mounts and storage menu) and use the "cp" (=copy) command to copy the important files over, like
Code:
cp /sdcard/afile.dat /path/to/external/sd
(sorry don't remember where CWM mounts the external SD at the moment, IIRC it's something like /mnt/emmc, but I'm not sure right now)
The cp command can also use wildcards like "*" for all files in the given directory.
Hope that gets you closer to saving your data.
I know this may sound cliche.. Have you tried turning off your phone ans remove the sd card and re insert it back in... And boot back up?

Thanks! Will try that in a few hours when i get home. Is there any chance i could do a "cp /mnt/sdcard/" to copy the whole sd at once? But perhaps something could go wrong since the ext sd is mounted in /mnt/sdcard/external_sd
Bah i dont know.... Any command genious here who can help me further?

Yeah, with the external mounted in a path inside the internal - that will somehow get you some troubles.
Let's consider for a moment it's at /mnt/emmc, then you could do:
Code:
cp -r /mnt/sdcard/* /mnt/emmc/maybesomesubdirifyouwant/
If the external SD is mounted somewhere you can't use it (like inside the internal - but IIRC CWM doesn't do that) you can just unmount it with something like this:
Code:
umount /mnt/sdcard/external_sd
then mount it somewhere else with
Code:
mount /dev/block/mmcblk1p1 /mnt/ext_sd
.
If you want/need to create a subfolder in /mnt (or wherever) you have to remount / as read-write first:
Code:
mount -o rw,remount /
mkdir /mnt/ext_sd

Solved it by formating. ;(
Hello, fellow gTablet users!
I'm kinda newbie here, so first of all my apologies to everyone if that was already asked, 'cause I did some research on the matter and couldn't find all the necessary info for solving my particular issue.
Ok, so here's the deal. I was using my gTab for about half-year now. When I received it, I installed VeganTab-7 Ginger Edition on it (thanks for the devs - very nice ROM!) and it worked flawlessly until yesterday. But then something not good happened and the tablet stopped booting. Now it starts from birds screen, goes on to G-Tabdevs screen, after which VeganTab GingerEd boot screen appears, it has flashing letters for a couple of seconds and then tablet goes black and tries to boot again. I guess it's a boot loop so it's kinda soft brick and I'll have to do wipe data/factory reset through CWM to solve the issue. So this isn't the biggest problem - I've already found all the instructions.
The real problem is that I didn't make backup of my data (guilty!), but I don't want to lose some of it, especially the browser data. I was using Opera Mobile, so I guess that its data should be on /data partition. So I'll need an advice on how I can dump the necessary data before doing factory reset!
I've already tried connecting to desktop, using guide from this (http://forum.xda-developers.com/showthread.php?t=1010943) thread (third method from it), but it didn't work, at least on my Win7 Pro x64 SP1: the tablet shows as removable disk, but I can't access it. I tried to mount /data or /sdcard partitions through CWM recovery menu, but it tells me that it can't find /dev/block/... - I guess that's block device, associated with those partitions. So what are my best options of backuping data?
And the last question: I'll probably install some other ROM just to try something different, but unfortunately I don't remember what loader I have. I'm nearly sure that I installed VeganTab for 1.1, 'cause I did it back in May 2011 and there wasn't one available for 1.2 yet. But just to make sure: how can I find my loader version before I do reset? Or maybe I just have to do the reset and look for it when back on stock ROM?
Seriously, guys, doesn't anybody know how to solve these problems?
Boot into CWM first, then try mounting both /data and /sdcard using the CWM menu. Note down the exact error message displayed in each case. Then connect the USB cable and run these ADB commands on your PC:
Code:
C:\> [B]adb shell dmesg >dmesg.txt[/B]
C:\> [B]adb shell fdisk -l /dev/block/mmcblk3 > fdisk.txt[/B]
C:\> [B]adb shell fdisk -l /dev/block/mmcblk2 >> fdisk.txt[/B]
Post the error messages and those 2 .txt files here.
Thank you for reply, rajeevvp.
When I'm trying to mount /data and /sdcard it says respectively:
Code:
E:Can't mount /dev/block/mmcblk3p2
(No such file or directory)
Error mounting DATA:!
E:Can't mount /dev/block/mmcblk3p1 (or /dev/block/mmcblk2p1)
(No such file or directory)
Error mounting SDCARD:!
Unfortunately I didn't have ADB installed. Now I'm trying to use the guide from here: http://forum.xda-developers.com/showthread.php?t=902860, but fail on step 4, cause there is nothing like "Nvidia harmony" appearing under other devices in my dev manager, just "Nvidia Tegra 2 USB Device" under Disk Drives and "USB Mass Storage Device" under Universal Serial Bus Controllers. I guess these devices are gTablet's internal memory presented as disk drive...
I'll try to install ADB and then write back how it worked.
Interesting error messages. Now I really have to see those text files.
If you're having problems installing ADB on Windows, try using Linux.
Ok, thanks you very much! I'll try that, but unfortunately tomorrow, as it's already too late here.
Btw, I read your post about linux - you're suggesting Knoppix Live CD there. Is it mandatory to use it? I mean I already have PartedMagic live CD burned, maybe I could use it instead...

Ok, I finally managed to do it. Sorry for the delay.
The files are attached. Did everything how you told me.
Actually I don't think that I understand too much in Android inner mechanics But having looked through these files, I thought that inner sdcard device (mmcblk3) doesn't seem to produce any strange behavior...
Btw, thanks a lot for your advice about using Knoppix - it's really very easy and handy!

You have lost your /data partition altogether. You are supposed to have 2 partitions on that internal SD card: a 14GB FAT32 partition and a 2GB ext3 partition. You only have a single FAT32 partition spanning the entire SD card now.
I may be able to help you get both partitions back if you give me these details:
1. How and when did this happen?
2. Current ROM.
3. Current version of CWM.
4. Did you try to repartition the (internal) SD card recently?
5. Have you ever repartitioned the internal SD card? If yes, then using which version of CWM?
6. After you noticed the problem what steps did you take to fix the problem?
Yeah, I remember I was curious where it stores OS's kernel if all it has is FAT32 partition - now I get it...
Ok, here are the details:
1. I don't really know what has happened, but I guess that it happened when I tried to use tablet like cardreader for microsd card. During that I sort of formatted external sd - maybe that actually was internal memory? I checked through file manager though, and all the files seemed intact...
2. VeganTab GingerEd from this thread: http://forum.xda-developers.com/showthread.php?t=1031250. I'm pretty sure that I didn't install anything except for it.
3. Don't know. But it says ClockworkMod Recovery v2.5.1.1-bekit-0.8 in recovery menu, so I guess its version is maybe 0.8.
4. No I didn't, at least intentionally.
5. I think I did it just once, when installing the ROM. I'm pretty much sure that I used this instructions for repartitioning: http://viewsonic-gtablet-for-dummies.webs.com/repartition.htm (not exactly this, but I did the same as it's written there). To install the ROM I used the instructions from the ROM thread, mentioned above. I didn't whant to do a lot of modding, just wanted the device to work at least better than with stock ROM, so didn't try to change any other low-level things.
6. I just tried to mount partitions through CWM recovery and I tried wiping out cache partition and Dalvik cache. Nothing else.

The OS kernel is not stored on the SD cards. They're stored on a "boot" partition on the NAND flash. And, if the OS was messed up you would get hung up on the initial splash screen (the one with the 3 birds)--you wouldn't go into a boot loop.

That's what caused this problem. CWM-2.5.1.1-bekit-0.8 does not work on the external SD card (but, CWM-2.5.1.3 and CWM-4.0.1.5 do).
Did you format the internal SD card using CWM?
I checked through file manager though, and all the files seemed intact...
Click to expand...

Files where? The internal SD card or the external one? And, how did you check this? After formatting the internal SD card, the very next boot into the ROM would've put you into a boot-loop because the /data partition is missing.
I think I may be able to get stuff from /data, but, everything on /sdcard is most likely gone. (Actually, the files are most likely all there, but, without direct access to the tablet, it's very difficult to get the retrieve any of them.) Just don't touch the tablet until I've figured out the commands you will have to use.
That's what caused this problem. CWM-2.5.1.1-bekit-0.8 does not work on the external SD card (but, CWM-2.5.1.3 and CWM-4.0.1.5 do).
Did you format the internal SD card using CWM?
Click to expand...
Click to collapse
No, I was going to format external SD card and I tried to do it through Android (or maybe VeganTab) menu. I think that doing this, I could accidentally format internal SD, but I'm not sure this could be done from within the OS. During the same logon session I checked files on internal SD with file manager and all of them were where they should have been. So I thought that all was ok. But when I rebooted next time, it wasn't booting... That's why I told you that maybe it was because of formatting.
And just to be clear: I didn't do anything using CWM after it stopped booting, apart from wiping system and Dalvik caches.
Do you have a large capacity micro SD card (anything larger than the maximum amount of data that's currently on the internal SD card) that you can use to save retrieved data into?

OK. Format that micro SD to contain a single DOS partition; then we'll proceed.

Ok. That's done.
Boot into CWM, go into the "mounts and storage" menu, unmount all mounted partitions, connect the USB cable, and run these commands using ADB--do not back out of that "mounts and storage" menu while we're fixing this. We're trying to see if the data on the current /sdcard partition can be retrieved.
Code:
$ [B]adb shell[/B]
~ # [B]mount -r /dev/block/mmcblk3p1 /sdcard[/B]
~ # [B]ls -l /sdcard[/B]
If the ls listing looks OK, then we force a filesystem check before copying the data to the external micro SD card:
Code:
~ # [B]mount -r /system[/B]
~ # [B]umount /sdcard[/B]
~ # [B]/system/bin/fsck_msdos -f -y /dev/block/mmcblk3p1[/B]
If the listing doesn't look OK, then the data on /sdcard is lost.
Post the exact output of each command.
Ok, mount says this:
Code:
mount: mounting /dev/block/mmcblk3p1 on /sdcard failed: Invalid argument
and ls after that gives no output - I think it shouldn't give any, 'cause I didn't mount anything...
Does this mean I'm screwed?
Try this mount command:
Code:
~ # [B]mount -r -t vfat /dev/block/mmcblk3p1 /sdcard[/B]
The same result.
FYI:
I have 2 CWMs for my NT,
1. app to flash CWM internally.
2. in the case where above is broken, 50mb SDCARD CWM method to boot up from SDCARD
I also have galaxy s i9000 and htc sensation.
the reason why I need ADB in CWM is because I want to resize the partition of my NT to increase the sdcard area from 1GB to 11GB.
but none of my 4 computers can detect NT in ADB shell.
Win7, Win764, WinXP system.
tried with uninstalling adb driver anddifferent port restart cable etc.
When I go "ADB SHELL" it returns device not found after starting the daemon.
I am certain that this is not an issue with my PC as I can connect my other phones, galaxy and sensation in ADB very easily while they are in CWM.
just like that connect and driver is detected automatically, and I can connect via ADB shell NP.
I have seen a couple of people on the forum who were successful in resizingg the partion in CWM via ADB shell,
Could anyone please advise on this?
Thanks.
Instead of using CWM, you can use a bootable full nook OS disk with ADB enabled - I know Adam posted one. Copy parted to it and comment out the vold.fstab and vold.conf lines that mount /media and /sdcard so when it boots you don't get told you can't resize mounted devices.
I did it the fugly way, forced a hard reset by 8 failed boots to do the formatting and reinstall, and it worked.
I also had backups off-device of the first 7 partitions to restore from if I needed them, made via
dd if=/dev/block/mmcblkX of=img.X and then copied off-device so if I really hosed something I could roll back.
Hello everyone, I'm in desperate need; any hint would be highly appreciated:
My GT-I9100 got drenched in a thunderstorm I encountered on my vacation. Unfortunately, I saved all of my pictures to the internal SD which is now inaccessible. :crying:
What the Phone does:
- When I start the phone it gets stuck at the "Samsung-screen"
- When I try to enter Recovery I get the CWM logo and the message "CWM-based Recovery v6.0.3.2". However the phone will restart after a few minutes and not actually go into recovery
- I can go into Odin Mode (Download Mode)
- I can connect on adb while recovery is supposedly loading (before the phone restarts) --> I can't mount the internal SD card (assuming from fstab that it is /dev/block/mmcblk1p1 or /dev/block/mmcblk0p11; both files seem to have a size of 0 KB); "mount -a" via adb shell freezes the phone.
What I tried/hope for:
My primary goal is to recover the pictures from the internal SD, not to get the phone running again.
- I tried to access the files via ADB. However, my understanding of the partitioning/file system is quite limited. The file system I can see via adb does not include the files I was used to find with my file explorer on the phone. From /etc/fstab I assumed, that the internal memory (that contains the DCIM folder with the pictures) is actually mounted from a file in /dev/block/ called mmcblk1p1. Trying to mount it gives me the following error:
"mount: mounting /dev/block/mmcblk1p1 on /sdcard failed: No such file or directory"
Using adb shell (ls -s) I realized that all files in /dev/block seem to have a size of 0.
- I tried to reflash CWM using ODIN --> Odin on my Computer force closed (both v1.85 and v3.x)
Is there any hope to recover my data? Please share your opinion; any help is highly appreciated!

Hi,
Galaxy S II 16GB 2.5 Years old.
I friend came to me with a problem : Waze can't start because it complains no access to sdcard (internal, no external present)
A bit fiddling and I see /storage/sdcard0 is mounted as RO!
I remount as RW, and I can now start waze, but as soon as I use the phone further, the mount reverts to RO.
I try to format it via recovery (philz) but it fails deleted odd named files in DCIM/Camera/cache.
So I try to delete the files myself but it fails.
Next up, I mount usb storage in recovery, and run windows Checkdisk, it finishes while fixing some stuff, the format still doesn't work.
Eventually using Minitool I am able to format it. BUT, now, when I boot android, it says the internal storage is damange, and attempt to format it via Android fails always.
Still, when I boot into philz, and mount usb storage, i can browse it via my W7 PC, copy and delete files freely. So I guess something is not mounted or formatted correctly. I decide to reinstall stock rom with Odin + repartition.
So I take pit file from a thread that aims to increase /data at the expense of internal storage, and I find the stock pit there and use it.
Rom flashes fully, but sdcard still not working.
What I want to do is :
Boot into Recovery and use Android commands to properly mount/map this so the phone recognizes it.
I have linux knowledge, I know how to get around a linux shell and use VI and permissions etc. I also messed sometimes with fstab on a pc to set up mount points, so I am not a complete stranger. I am rooted and need help
Any help would be appreciated.
So, I searched the net for quite a few hours, and found this post :
http://forums.whirlpool.net.au/forum-replies.cfm?t=2147315&p=-1&#bottom
Which solved my problem
I registered on that forum to thank the dude!
This command solve my problem :
newfs_msdos /dev/block/vold/259:3
I knew it will work the moment I saw the 259:3 which I saw in logcat that android cannot format.
Good work finding a fix yourself Hopefully other people in the same situation will find it useful
