Hello folks!
Can someone tell me how to format the Internal SD of this phone?
And, while we're at it, is it possible to format it as ext2 or f2fs?
TIA!
Ookay. I did a lot of research, and to answer my own question:
The Internal SD can NOT be formatted, because it's not a separate device, but merely a directory under /data. /data/media, to be precise. But it can be ERASED/wiped.
Wiping /data now no longer format the /data partition; rather, it simply deletes everything under /data except /data/media.
CWM (or other recovery) should have a separate command to erase/wipe the /data/media directory.
And to find out what filesystems are supported, one should do cat /proc/filesystems
Thanks for reading! I hope this information can be useful to you, too.
forever alone

Hi all... Here there're many dev so maybe i'm so lucky to find someone that can help me....
I'm going to convert my phone's partition to ext4 but i have problem with /data. This because the phone has 4 gb of internal memory that Samsung push under /dev/block/mmcblk0. This memory is partitioned in three part /dev/block/mmcblkop1 (internal SD) /dev/block/mmcblkop3 (/data) and /dev/block/mmcblk0p2 (empty).
How can i format /data into ext4? I tryed different way but the phone doesn't boot. What is the correct way to make it?
My Phone (GT-I9003)
UPDATE: recovery can mount it without issue.... init.rc not.... why???
on GDXv25 abd alfv8a have all the extra goodies for vold and all that. I change my SDCARD to a bigger one. format a partition for ext4 and leave the rest as default. On moving old stuffs back to it it seems to behave very well. Then I decide to move some of the apps to offload internal storage. The moving seems totally ok but after reboot my sdcard seems not be able to mount anymore. Go into CWM recovery and try to mount my sdcard. It says error mounting /sdcard yet I could succesfully mount my ext4 partition. At this point should I go ahead and re-format the sdcard again? What happens to those apps that I offload to the sdcard? are they toasted?
I'd to get some opinion before I re-format it since it will bring me over the point of no return. I still have no clue why all of a sudden after the moving of my apps that the partition won't mount anymore
On my linux I try to mount it via USB... it gives an error saying can't mount coz it can't read superblock. I gather some operations must have wiped into superblock. Sh*t hits the fan so to speak
by the way it is a new sdcard ... I dun think i damage it. But from CWM I can't even go ahead and format it because it says error mounting the partition.
I am amazed - I thought you don't need to mount before you can format. what's the deal here? I can't mount and I can't format?

That error message simply means that the ext filesystem in the sd-ext partition is kaputt and needs to be repaired (for example, manually restore a copy of the superblock) or formatted.
And that's your reason why you ran into problems ... something went wrong as you moved your old stuff onto the new card, and the next app you put onto the sd-ext finally triggered the problem.
Of course there's also the slight chance that the phone doesn't like the SD card.
finally I am able to format that sdcard by inserting into my kodak video playsport camera and format that from there! It's ridiculous that under CWM I am not able to do something as simple as formatting. That should not be a "feature" at all! Error mounting the card I could accept that but not able to format a card with screwed up superblock that's not acceptable.
With this exercise, I realize how valuable a backup it is. With all those apps xferred to the sdcard, I practically cross a bridge. Even with old usable card re-insert into phone those apps are gone and are no longer available. Only a backup (of course on a usable putaway MMC card) could have saved me all the trouble.
I still dunno what have gone wrong in the first place. Perhaps there's something I dun quite understand about moving apps to xternal storage.
Hello,
Sorry, not working like on sgs 3 and galaxy note 10.1. Dont apply now. I m working on a fix with vold.fstab, but format changes with jellybean.
Ported from scripts created originally for Galaxy S 3.
This script swaps internal and external sd storage from init.d.
- You must have a JellyBean Stock or Stock Based ROM
- Must be rooted to flash.
Attached to this post, you will find the CWM flashable zip.
This have zero chance to brick your device, but I cannot say if your SD card doesn't have any issues etc... so don't blame me for data loss or anything.
This script will NOT COPY DATA from your sd, so you will have missing data after you restart the phone.
The data is still on the original internal SD, so you'll have to copy it back to your bigger sdcard's root.
Code:
#!/system/bin/sh
#extsd2internalsd is a modification that allows to switch internal sd to external sd and viceversa. With this you can use default internal sd only for app storage #and the external sd to store all apps resource and all others stuff. The resut is a very big increase of installable apps on gs3
#All credits to Mattiadj of xda forum for the idea and script and to mike1986 for the cmw zip.
#Script Modified for SgNote N7000 by aureusz
sleep 5
busybox mount -o remount,rw /
#Tries to mount as vfat
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:9 /mnt/sdcard
#Tries to mount as exfat
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:9 /mnt/sdcard
#If Sd has been mounted, mount internal SD as extSdCard, if not, do nothing, Android should mount it back as internal.
if busybox mount | busybox grep vold/179:9; then
busybox mount -t vfat -o umask=0000 /dev/block/mmcblk0p11 /mnt/extSdCard
fi
Only problem is, if you use usb mass storage connexion, instead of mtp, it will swap back sd cards.
If you want to remove the script, simply delete the file 11extsd2internalsd from /etc/init.d/ with root explorer or a similar app.
Restart the phone and the problem should disappear.
I'll look into a fix for this.
Strange stuff happenning after first reboot (app2sd make apps disappear). Removing file and placing warning back

Or you can simply switch mount points in vold.fstab

The problem with this method is that, if you remove SDCARD, the phone will not mount internal SD back to it's place.
With this script, the internal SD will remount back to internal sd path.
I'm not sure, but that's how I understood it when I read the thread where they talked about this method.
Correct me if I'm wrong, I pretty much a noob at this.

The solution to that can be decompiling framework-res.apk and editing file storage.xml
Make removable flag true for both storage.
This may or may not work but worth a try.

I'm definitely interested in all options regarding this issue, this has been a big hurdle for me on android with sd card slots, so I took to myself to fix it. I know it's easy to do in ASOP roms but, I missed some S-pen features.
Until now, people used bindings for some directories, for large games data, but this proved not to work for some apps, while this solution works for every app.
Spotify for example lost its synced library, because I think the service would check the synchro of the playlist at device startup, and the folders were not yet mounted... etc.. now, it's flawless.
EDIT : not so flawless, looking into modding fstab as suggested by neobuddy89

Is it possible that you post the vold.fstab where the mount point is switched for internal and external SDcard? Thanks.

...what this means: "Mount and storage > format /system & format /preload"
does it mean that if i format i will lose every single piece of data on my sd card and internal storage? if so why is this recommended because i imagine it would wipe out the zip that is stored either on external or internal storage, how would i proceed to flash in that situation? is it safe to format mount and storage without worrying about data such as zips and folders that conatin large game files?
please give me a detailed explanation
thanks in advance
Mounts and storage
These let you directly format any of these partitions. This should be used with extreme caution as formatting any of these partitions will result in losing all data on them, especially the boot and system partitions. Formatting the system partition will remove your ROM and leave your phone without an operating system unless you restore or flash another one before rebooting your device.
* Okay if you want to flash a new Rom:
format /system > will format everything in /system
* Okay if coming from TW and switch to AOSP/CM:
format /preload > will format everything in /preload
+++++++++!!!!!!! CAUTION!!!!! +++++++++
format /emmc >
format /sdcard >
format /sd-ext >
Those will wipe your internal and external SD.

it will not wipe your whole internal storage or for short your personal files. /preload & /system are just system folders where your phones stores all the system files system apps, etc, just like "Program Files" in you Windows Computer
Hope that helps
So go ahead and wipe clean before flashing a new rom, just make sure you have rooted your phone already and installed a safe kernel...
Thanks for your help.

I'm attempting to format my external sdcard to ext2, just one single partition (no apps2sd magic).
The reasons are to have the ability to store >4GB files on the card, faster read times, and not needing compatibility with any M$ systems/PCs/Junk, journaling (>ext2) is not needed.
At the moment, I'm running a CM based ROM (cyanfox) and will likely try this out on a moto/stock based ROM after.
Here is my progress so far :
I'm able to mount the SD manually, though with some hoops being involved. The bionic will not mount it automatically, and is constantly telling me that it is unsupported/empty/needs to be formatted in the storage menu, and a permanent notification.
In a terminal shell, I can mount the device (/dev/block/vold/179:97) by specifying the type only as ext4. This is definitely not ideal, but I get errors when the type is specified as ext2 or ext3. (error : mount: Operation not supported on transport endpoint ).
At the moment, I've made an init script to mount the sd at /storage/sdcard1 but this doesn't cause android to think that the actual sd is mounted properly (empty sd notification still exists). Though it is at least mounted.
And I have edited the fstab file at root to change the sd type from vfat to ext2, but this file rewrites itself at boot. Unfortunately I'm not able to set an immutable bit on the file.. (android is not a type writer).
The ext2 filesystem has been checked for errors, does have files written to it, and is able to be read/written to in android after manually mounting it. Android just insists on a fat partition though.
Any help/tips would be appreciated. I'll update this thread in case anyone else would like to apply this as well.
Also, if I'm missing something blatantly obvious, please let me know
