hi, I have another problems with update
I flashed 4.3 update, and noticed that I dont have my pictures, search in sdcard and there is any of my files, but... free space is exactly the same, i made a scan using disk space for examinate space structure and appears lot of used space, my files, as system space, more han 6 gb, but I cant access it,
I tried access through root explorer looking in all folders but I cant find my files, but there is, free space in sdcard is exactly the same before flashing
what is the problem? why happend that?
well, I dont know why and what was the reason but I made nandroid backup this afternoon, I never do, but I feel so lucky today
restore nandroid buckup, and all my files are there again!!
my files with 4.3 appear like system data, reserved space
same scan with disk space and now appear all structure of folders and files, and the winner folder was "media", containing all my files, looking with astro explorer and there is all
why this has happend? is not compatible??
lot of years with android, but, increasingly tired of this strange things
You need to learn the basics, start in general forum sticky threads -there is one on storage which has a link to the changes brought by 4.2 & 4.3.

By the way, the solutions posted also didn't help me any. There was only new sd data created at sdcard/0 (and i9305 doesn't have its sdcard mounted in data/media we have ours located in storage/sdcard0 on 4.1.2 and by the looks of things storage/sdcard/0 on 4.3? that means that all data that is missing is located at the parent folder above 0. I tried searching and searching and found no way to access my sdcard data other than to flash back to 4.1.2 and then retrieve it and then flash back again.
Could this be corrected with a symlink in the updater script?
What I mean is, that there is obviously an error somewhere along the line? i9305 had it's sdcard located at /storage/sdcard0 then when we flash to 4.3 it is located at /storage/sdcard/0
so.............................................................................. ^^^ this is obviously an issue.
I have not attempted symlinks on SD filesystem and AFAIK attempting to symlink SDcard to internal system partition doesn't work; System to system DOES, but I am unsure if sdcard to sdcard can work?
Say for instance adding a symlink from sdcard root to sdcard/0/root.....could this be possible? Or will this cause media scanner to go haywire?
And if so could a .nomedia solve this?
I feel like trying this. I will post back here if I have success.

I'm stupid, I knew that FAT32 doesn't support reparse/symlinks
Bugger. This all relates back to a KNOX issue AFAIK, 0 meaning default user, so I can't effectively link even if I wanted to.
vold.fstab between both versions is identical so the coding is internal within either the framework of some other system file....deep deep within the depths of smali land where I never wish to venture.
I'm wondering if busybox can overpower what RootExplorer doesn't support with a blatant symlink no matter what? hmmm

How to move applications & games data to external SD card on Samsung Galaxy S3?
I take my Samsung Galaxy S3 as example. It should work on rooted Android phone with external micro SD card.
Old Gameloft games data are stored at /mnt/sdcard/
However, latest Gameloft games data are stored at /mnt/sdcard/Android/data/ just like other Android applications and games.
With Directory Bind, you can move one folder by one folder to external storage at /mnt/extSdCard/
I won’t move all applications and games data in Android/data folder to external micro SD card because it is much slower compare to internal memory.
Therefore, I only move those unimportant or less frequent used applications and games to external storage with Directory Bind.

No. Symlinks (and hardlinks) only work within a filesystem, not across partitions.
This is a kernel-feature called bind-mount.
The underlying command is: (Make sure the destination exists)
bind -o mount /from/source/folder /to/destination/folder
I was trying this last night, but couldn't get the settings to persist. I was trying with gta3 and put the exact settings you have above in, ticked the box to move move files, and the files moved but the settings didn't appear on the main screen.
Hi ,
I would like to know how to delete the bing and restore original app directory.
If I hold down on the blind apper two paths and under these two entries "delete" and "save"
What should I do? I run last version of app "o"
I've read all the page of the topic but I found information only to create a bind and not how to delete it.
Thanks in advance
Just hold on bind entry & delete. Simples
Sent from my GT-I9300 using Tapatalk 2
Not exactly sure how it works.
Moving seems to be working. But the directory stays on internal sdcard but are files moved because there is more space.
But when I reopen directory bind I can't see binded directory's anymore?
How to unbind then?
And when I delete directory on internal sdcard the game doesn't run anymore!

Hi Carlos, I'm using the same configurations that you show on your screenshots but when I try to open for example Aura, it wants to download all the data again. This happens also on the games.
I am using a Galaxy S3 Us Version, rooted, with Adama 03 kernel and redruM rom, Android 4.04.
Thanks!
Awesome!, works perfectly on omega9
Thanks!!!
I got many application crash or force close when the directory bind running..ex TB,gapps,and many other..how to fix it??

I'm using link2sd app. Works pretty well
Sent from my GT-I9300 using Tapatalk 2
This is done by creating symbolic links.
What you're making is a way to point that any operation into directory /x needs to be done into directory /y. Because of this, you can't delete the original directory or your games won't run as you are deleting it on /y (/x point to /y).
I do this on my computer to use my RAM Disk with browser, temporaries, downloads and such.
symbolic links and bind mount is two different thing. symlink doesn't supported by the (ex)fat16/32 filesystem, so only the bind mount will work.
great app but a directory browsing feature will be great, writing a long directory name is painfull
edit: found the directory browsing feature

Mine does not read at all won't pick up my pictures or music even if it scans and also no way to access it with file explorers. The page you linked me to only had wifi questions on it.

^This. Use something like ES or root explorer and go up a level and there should be a folder called storage with an External_SD folder inside (or something of the like) and another called sdcard0 that goes to the internal SD
This also should have been posted in the Q&A section, for future reference.

is this what u meant? i've heard that some people were having this issue and that if u flashed the 2 files in this post that it fixed the sd card not being read. after i flashed these 2 fixes and ran scan media all my pix showed up in the stock gallery

yes I did check under external_sd that directory is there, but doesn't take you to the card. It's just an empty folder, also the same from computer.

I ran those two zips, and everything is still the exact same. If you go to external_sd it just says this folder is empty. When you plug into computer and access it says "device has stopped or doesn't exist".
more info
I don't know if this is relevant to anything, but external_sd has the wrong date it was created it shows 1/2/1970. Just thought I should mention this.
have u tried putting the sd card in a different device and reformatting it to make sure its not the card? Or tried using a different card in the phone?

As I said earlier /sdcard/external_sd is empty for me as well. However /storage/external_SD is where the content shows up. If the card is empty when you mount it in the computer, it may well be empty or corrupt. Formatting (erasing all content) may be necessary.

Yes I just looked there its empty as well, and media scanner can't find anything. and per vinniemac84 instructions, I removed the card put in adapter and put in computer everything is on it, I also just put the original 16gb card in phone which was removed from phone the day I got it and tried to create a folder in both places and it tells me could not create directory. Also in setting under storage it shows nothing about an external card no options to mount it or size or anything. usually even if you don't have a card in the phone it will show the option to mount a card.
Okay. So the Galaxy S3 16GB model has a useable storage of 11.35GB.
Below is why I'm confused, and why the storage just doesn't add up. It's either that, or I'm just a retard.

I open up root explorer:
Code:
/storage/emulated = 2.00GB
> /0 = 1.00GB
> /legacy = 1.00GB
2. What is the difference between /0 and /legacy?
From what I can see they hold exactly the same data, but 2 copies of it in 2 different locations.
Why is Android using up twice as much space as it needs to?

Hi Bortak,
Have a read of the link about 4.2 and sdcard in my signature. I think it contains all your answers.
0 and legacy are the same btw. As in they're both links to the same location. No duplication exists

Hi rootSU,
Thanks for the reply...
So is it just a case of root explorer being confused, thence confusing myself?
Now when I check the filesize of /emulated, it is shown as 4.09GB
When I check the filesize of /sdcard0 (/0), it is shown as 2.04GB
Also, even if that is the case, this still doesn't explain why Android doesn't see about 4GB of my internal memory, or doesn't list it in the breakdown.

It just never will be that simple.
But to sum up, /data/media becomes /data/media/0 when you upgrade to 4.2
In /data/media you should only have 0, legacy and obb. Anything else there (eg /clockworkmod) will take up space but not be reported in storage menu. Thsi data shouldn't be here so with root explorer, move anythign in /data/media that isn't 0, legacy or obb into where it should be (0)

I completely brain-farted with the whole storage, bit.. and forgot you access the sd-card from /data now.
I just read this:
Anything else to be aware of?
Yes actually, many older recoveries still probably see /data/media as the location of /sdcard, so nandroid backups may end up there instead of /0. For example, often you end up with /data/media/clockworkmod instead of /data/media/0/clockworkmod. Some recoveries have a setting to change the location to /data/media/0 (Such as Philz recovery)
Because the Settings > Storage > sdcard shows the space free and used for /data as "sdcard" but only looks in /data/app, /data/data and /data/media/0 to get the breakdown of what is using the space, you will find that anything just in /data/media will show aup s used space, but the breakdown of apps, pictures, media etc will not show these files so it appears that they do not add up.

Yeah, it's usually CWM that does it. Not sure how newer ones manage.
I do recommend you try Philz recovery if you haven't already though. Its CWM but massively enhanced. You can toggle whether it uses data/media or /data/media/0 too.

Neat. Gonna try the kernel in your sig too. I don't know if it's just me, but my phone doesn't play along nice with Siyah & CM10.1, and I want something with better sound.
Since I got the new version of 4.1.2 the device memory is completely full and I can barely do anything with the phone.
The apps are only taking 400MB and I have no idea what's taking the rest.
Please advise.

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

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!

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?

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 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!

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.
