I want to be able to copy files >4Gb to my Touchpad. This is so I can watch HD movies on the device.
I already tried adding resizing the media partition and adding an ext3fs partition using "Tailor" (a webOS app). Although this is easy and it worked, I couldn't find any way to have this partition mount at boot time and be seen by my Android apps.
There are a couple of posts out there on the web from people claiming that they "reformated" the shared partition (/media/internal) to ext3fs successfully.
Has anyone here done that, and if so (a) how? and (b) were you able to have it mount and be visible from android apps?
Otherwise does anyone have any suggestions please?
cheers

Getting somewhere...
I tried again having found out that the ext3 partition I created in webOS is found at /dev/mapper/store-ext3fs
Under Android - everything below is done in Android
I am able to mount this partition to my fake sd card (I just created a folder there called "ext").
Code:
su
mount /dev/mapper/store-ext3fs /sdcard/ext
I found that copying files by USB doesn't work while my ext3 partition is mounted, which is a pain - would be good to get that fixed. Anyone have any ideas?
I am now testing copying over a >4Gb file to my ext3 partition using ftp client. Will take some time on my crappy wifi, hence the comment about fixing USB.
I found that in order to make the ftp process work, I had to give full permissions to this folder.
Code:
chmod /sdcard/ext
I am a noob, so if anyone can help me with a less insecure set of permissions I would be grateful.
I'll post an update later on.
Nah, didn't work. After a few hours of copying I went to bed, this morning the folder is empty. I'm not sure if there was an error or anything.
My suspicion is that it crapped out when it got to 4Gb because even though the partition is ext3, it is mounted at a mount point on a FAT32 partition.
I realised I can test this more easily and eliminate possible network errors or ftp client instability, I'm running
Code:
dd if=/dev/zero of=output.dat bs=1024 count=51200000
within my /sdcard/ext folder (my mount point), this should create a 5Gb file.
I'm expecting this to fail, again because even though the partition is ext3, it is mounted at a mount point on a FAT32 partition. If anyone can help me to mount the partition some other way so its not mounted in a FAT32 partition, or point to another method to overcome the file size limit, I would be grateful.
thanks
Paul
That worked!
dd-ing a large file worked. I think I got my calculations wrong so when it got to >7Gb I just stopped it.
Now it would be great to get this working such that I can use USB instead of ftp to get my movies across.... Anyone?

USB transfers not working
Anyone help me identify partition number for my ext3 partition please?
My ext3 partition is all working except when mounted I cannot use USB transfer.
Believe this is because my vold.fstab mounts the first available partition as SD card.
So would like to know correct partition number for SD card and ext3 partition.
I gave up on this in the end. Assured by clearly very clever jcsullins over on the cm touchpad IRC that the partition doesn't get a number and I would not be able to get my USB file transfer working. I also found the available media players (or maybe CM itself at the moment?) unable to cope with my 720P movies.
All is not lost though. I'm having more luck over on webOS using touchplayer and an overclocked kernel.
Thanks to those who tried to help with this!

hi...
i had a similar problem on my sgs2 (with cm 10.1-20130710-NIGHTLY-i9100). it turned out to be a bug that was filling the folder /data/log with log files because of connection problems with the cellular network. the log files were using up more than 1 gb of space. if you have root you could take a look if that's using up your space.

Seems /data partition is full. It's unaccessible without root.
I have looking similar situation 2 times, and solved with root magiic.
First time my external sdcars got a corrupted file with strange name - nobody knows how it was, but then media indexer gone mad - it consumes cpu for a days, and fill /data volume with kind of incomplete indexes.
Happy end was - to fix extenal sdcard filesystem, then clear media indexer data.
second case was caused with flickr uploader program. because of error in program (now it fixed) it writes a tons of data into log file, pllaced inside /data. Was fixed by removing program with all application data.
Both of that cases was fixed technically without a root, but first step was running "Storage Analyser" in root mode - to find folder with abnormal large size on /data partition.

paranoidisc tell truth. I run a filesystem check and fix on my PC, because error was at SD card.
you still can run a check filesystem on a PC unil filesystem is FAT and volume can be exported via USB as block deice ("usb storage").
or u can try this method suggested by @esd from NeatRom
Install this on your PC

connect your phone in mass storage mode and delete it using unlocker.

Hi!
Story goes like this. I have here clone Samsung S4 that I wanted to update the software trough CWM. Unfortunately phone died at some point and now is dead. But, I made backup of the flash with MTKDroidTools and with SP flash tool... and here comes the problems... I can not flash backup back to phone because yaffs2 files are not good page/spare ratio. Thanks to members rua1 and Alex1948 now it is more clear how to change spare ratio on yaffs2 files. Unfortunately I'm not very good with Linux, last night I boot Mint 16 from USB stick and was trying to repair my files but without success.
So, my question is: is someone willing to repair my files in Linux (who understand Linux terminal better)?
Here are some details from phone

I only have problem with flashing yaffs2 files and secro.img all other are OK. If I try to flash those files I get this error
In attachment is mtd, dumchar_info, MTKDroidTools log and Sp flash tool log so you can see my file structure.Log from MTKDroidTools is from version 2.5.2 because I was using this version when I was making backup from my original phone (you will see other phones data just scroll down to MT6575)
I'm uploading original yaffs files to google drive so later I will update this post with some links.
Thank you all in advance.
Best regards

Hi!
First, thank you for your reply.
Yes , I did figure it out that my files are not OK. I was trying to make them manually in "yafey" for windows (software to create and edit yaffs2 images) but this software have to much bugs so one time it create system.img with full lib folder second time only half of lib files are there and also there is no option for spare ratio change.
So, MTKDroidTools did make my system backup in a folder on my PC but I can not make yaffs2 file from it because there is no software for windows that works fine (I don't use Linux). On Linux it is easy to do (at least for someone who understand Terminal commands).
So, I can send you my backuped system folder if you are willing to make yassf2 file from it (in Linux). Data and Cashe files I have create in yafey and thay are ok.
In yafey if I make new yaffs2 file and insert lib,etc,app,framework... it will not create all files in folders... and after that when I try to flash that created system.yaffs2.img I have error from BROM s_ft_readlen_not_page_aligment (4017) again problem with spare ratio.
I still have here my friends phone so if you have any idea what to do and how to do please tell. I made backup from my friends phone but same thing data,cache,system,secro files are not created correctly. I don't know why is this is it because of the MTKDroiTools or is it because of the phone?
Aaaaaaaaaarghh!!!!!
You wouldn't beleive what I just discover I just try to put my friends phone in recovery so I give a try to make backup.
NORMALY my friends phone don't want to go in recovery (just light on screen), so I have call my friend to ask him does he do something with phones recovery and he said YES i flash some recovery from net trough CWM and after that he can not go in the recovery.
CAN YOU BELEIVE HOW UNLUCKY I AM????????
If someone have any idea???
Hi folks,
I just attempted to access a microSD card formatted as exFAT with this adapter (https://www.amazon.com/dp/B013OIGJFE/ref=cm_sw_r_other_awd_4e-pwbFQRCK91). Although the card was detected I got the message that the format wasn't supported.
The phone did reformat the card as FAT32 which works fine but not for files over 4GB. A bit sad that exFAT isn't supported.
This is shocking ! To date all the newer Androids I had used has no issues supporting exfat format. It is indeed strange if exfat is not supported
This indeed is very strange....exFat is the new standard for external storage...how could Google overlook this?
Cost.. Exfat requires license and $$$
I'd like someone else to test it though.... Sometimes phones are picky about the microsd card and don't detect it properly

I have marshmallow on two devices and exFAT does not work. It's unfortunate and as it stands I have no portable ways to transfer files. I even connected to my computer and it didn't detect the internal storage.
I am going to be using Elementalx kernel as it supports exFat and I need it. I have a 128gb external sdcard that I use.

Not sure if you know, as default when you connect to your computer the default connection is 'charge only' you have to pull the notification down and choose 'MTP' connection.
Sent from my Nexus 6P using Tapatalk
Solid explorer with its otg plugin can access my exfat formatted media even though marshmallow displays the unsupported media notification.
This is on the nexus 5 though, my 6p should be arriving tomorrow.
Has anybody tried StickMount for exFAT support?
So I'm using the ElemantalX kernel and I still get warnings about the card not being a supported format

However now when I launch ES File Explorer I get a notice that only FAT32 and NTFS are supported ( I'm assuming it detects the card and the exFAT format). I've tried in other file explorers and can't seem to find where USB mounts.
EDIT: just tested using StickMount and I'm able to read/write without issue. However I'm still on the ElemantalX kernel.
I ended up using StickMount from Chainfire

Same, works great. Too bad native support isn't seamless though :\
Edit: any news on speeds that you're getting? I'm seeing about 10MB/s (MegaBytes) transfer speed using a USBC 3.1 adapter to PC but I'm not sure how to measure transfer speed on the phone.
Just use EXT4, very easy to get windows to read that as well.

This seems like the best solution. However, after some digging it appears that ext2fsd is only REALLY meant for EXT2 and EXT3/4 work in compatibility mode. However, ext4 seems to use an inode of 256 by default which is not supported by ext2fsd. If you can format your card as EXT4 inode 128 it should be fine.
However I just found this... Paragon makes an EXT driver for Windows 10 and its freeware for personal use (but needs to be registered). I think this is the path I'll take. Thanks for the feedback!
http://www.paragon-drivers.com/extfs-windows/
Solid Explorer with the OTG plugin works just fine (although as mentioned above, the compatibility error still comes up). No need for root, custom kernels, etc.
All,
I've done quite a bit of searching and can't seem to find a good tutorial or method for re-partitioning the NABI2-NV7A to remove the "addon" partition and reallocate its space elsewhere. I would ideally like to put the extra space in the system and data partitions. Has anyone successfully done this? Is it a bad / more risky than normal for XDA users are used to?
I currently have the 3.0.13 KK debloated ROM from n3wt and the latest TWRP 2.8.5.0v2 from aicjofs installed, as well as Links2SD setup with a second ext4 partition on my SD card. I have formatted the addon partition per terminal command instructions for the Nabi2 found elsewhere. Links2SD is not always reliable as it often causes the system to hang when moving data to the second partition. I have seen the post from ashahin1 that sets up this similar second partition without the need for Links2SD - is this more reliable?
Any advice or direction someone can send me in would be very helpful. Thanks!

The only way is by nvflash, and I am a little fuzzy on the whole thing since it was so many years back. The only solution that was "tested" was using some of the cache partition and putting it in the system partition. I created that solution and somewhere between 5-10 users used it and it worked. I also documented increasing data partition and found that while the tablet ran mounting /data/media/ was having issues. I wouldn't say it was any more risky or bad but it is definitely a very high user understanding to implement it. I have a tool posted somewhere here that does some of it by script but what you want would need to be developed for the data and addon partition(which could then be scripted). Short version. Taking from cache and adding to system worked no issue, increasing data(and I forget from where i took it) had some bugs that I think could be worked through but I stopped at that time.
I'll try and find a link to my notes but in general the issue is that the repartitioning through nvflash is not 100% perfect. There are 3 partition tables, one nvflash uses and a GPT style linux kernel uses(and it's backup). If I remember correctly when formating in nvflash it updates both partition tables but won't boot unless you restore the old nvflash PT(leaving the new modded GPT). It's also best not to remove a partition but shrink it down. In example below I wouldn't get rid of addon but make it 2097152 from 1572864000 then use the left over space to put on data.

You really can't go wrong as long as you grab the first 3 partitions before you start editing. The script I have out there makes a file "bricksafe.img" of those partitions.
Code:
nvflash --bl bootloader.bin --rawdeviceread 0 3072 nabibricksafe.img
Really as long as you have that it is impossible to brick a Nabi2(hardware failure not withstanding). Another common issue is the Nabi2 original came in 2 versions, 18 partitions, and 19 partitions. It's important to figure out which you have before starting. I could go on and on about this but it's been a month since your post so you may not care any more, or you may read what I have said so far and not want to try it so I will save my breath unless you want to try it.
This is where I start talking about nvflash stuff

I have honestly never been very interested in making external SD work as increased storage(nor do I own a Nabi2 anymore) but I told people for a long time that ramdisk was the way to go, so ashahin's method is one I would prefer although again I have never tried it.
aicjofs, thanks for all the great info! I'll do my homework and give it a try. My son recently got a gen 5 7" kindle fire. It's nice and I'm trying to resist the urge to do any mortifying to it. So that means I can play around with his old Nabi2 without upsetting him. I have some experience using nvflash to in brick my wife's old Asus Transformer TF100.
I'll let you know how it turns out.

The first 600MB is your EFI partition and you absolutely cannot delete it or else your Windows will not be able to boot. The last partition is used to store data for Windows recovery. While it is not a must be highly recommended.

because the size is almost the same of the 2 partitions I thought i had 2 recovery ones and wanted to delete one of them
the system partition EFI shouldnt it be smaller?
I think it got bigger when i cloned the disk (now using the cloned one)
You can resize it to 300 but I wouldnt recommend anything smaller than that.
my original disk I had had 2 file partitions c,d (which i merged to one before the clone) AND
one 100MB, 16MB, 658MB
the 658 was the recovery i guess
the 100 was the system? that became 600 on the clone ?
and the 16 ? vanished on the clone

Like mentioned, be careful with the partitions. I suggest doing some reading, on the required size needed per system. Just a thought.
Yeah not gonna mess with the size etc
Just wondering why my previous system was 100 and got 600
And what did the 16mb do? I guess nothing cause it was not cloned in the new disk
When you clone the drives, there is a chance where the software "scaled" the partition size, and in this case increased your EFI partition from 100 to 600. The 658 partition is definitely recovery because it is a NTFS partition.
Also it is good to know that EFI partition is always FAT32. The only thing I am not sure is the 16MB but I guess there is nothing to worry about since it is no longer there and only 16MB.. LOL
Microsoft reserved partition (MSR)
In Windows 10, the size of the MSR is 16 MB.
this got lost while cloning, still works though
