[Q] Format SD card to ext2

I bought new SD card i want to wipe my phone completely and install Darkys Rom. I formated my new SD card to ext2 in Ubuntu but my phone didn't recognize the file system. Then i used Clockwork to format my (external) SD card and what i did i formated my internal SD card. I'm completely failed. Can somebody give me step by step tutorial how to format external SD Card to ext2 or ext4. Also i would like to know if i will be able to copy data under windows when the phone is connected through USB.
Thank you
Sorry for my English

Hi! Please tell me why do you want to format your SD card to ext2 or ext4? There is no need for that. Just format it tu FAT and that's it. If you want to apply lagfix then do it under recovery with the lagfix option under advanced features.

I would like to have option to transfer bigger files than 4GB.

how do I format my external SD card to ext2? I have Samsung Captivate. I got Cygwin, since I use Windows. Does anyone know what commands to type in cygwin?
I want to put files larger than 4GB on my card as well.
I think this will be useful for a lot of people.

I found a thread http://android.modaco.com/content/h...an-i-bind-mount-e-g-system-sd-xxx-sdcard-xxx/
But I am a noob in Linux, and it would be GREAT to have step by step commands I would have to type in to format my external SD card, while its in the phone, etc
Possible problem I see is that the phone might not recognize external card if its ext2/3/4 . We might have to have small FAT32 partition on there as well? Or may be Froyo has that ability...

I'm looking into doing this myself, in my case so I can use symlinks to copy apps "data" folders (not the "data" partition, but the folders in /mnt/sdcard where apps put different things) onto the larger, external sdcard. It seems like it could be possible, just need to make sure the /etc/fstab file is updated properly, and of course make sure your kernel has the ext2 and/or ext4 modules loaded and running (which you probably will if you have a lagfix installed). I will play with this and post back my results here...

I have been looking for this myself for a while aswell, but on 4 different kernels and CWM v2.5 and CWM v3.0, I couldn't find any option on how to change the ext. SD to Ext4. If anyone knows how to then please post it here!

So, progress report...
Still no success in this matter, although I have learnt a bit today about Android's internal workings. After backing up my system with CWR, I first tried formatting my ext sd card with gparted on my computer. Bad choice... Even though no config files were stored in it as far as I could tell, Android "panicked" and decided to restore all my configs to default, severely crippling my system and making a lot of apps force close when I restarted the phone.
At that point I thought, since it is now broken, might as well play with it So the next thing I tried was formatting my internal sd card (only the vfat partition that gets mounted in /mnt/sdcard) to ext2, but this time using the "busybox mke2fs" command, on the terminal emulator on the phone. This seemed to be successful, and I could read and write to the new ext2 partition, although for some reason, I got the feeling that apps kept resetting their settings (not sure what caused this, didn't really looked into it much). So once that was up and running, I decided to modify the /etc/fstab file, like I would do in a normal linux environment, to automount this partition on boot, as ext2.
At this point I rebooted the phone, but hmm... Android converted the partition back to vfat. Not good. This leads me to believe there must be some kind of "recovery" commands run on startup, in case the system detects the partition is not the default file system, or something along the lines of that. At this point it got kinda late, so I decided to document my progress, restore (which thankfully left my phone the way it was at the beginning of the day) and call it a day.
So, things that I still need to find out:
1) How does the system convert the partition back to vfat on startup and how could I avoid it from doing it? Maybe by having a small vfat partition to fool it into thinking all is good and normal?
2) When I had my partition as ext2, I couldn't see it on my computer when connected via USB (I'm on a linux system so the fs being ext2 is not a problem). Wonder why...
3) If I had a small vfat partition, how would I go about mounting the ext2 partition on the same mount point after the system checks the vfat one? Maybe by binding it? Gotta look into that as well.
4) Finally, have to check why the apps couldn't maintain their settings after a certain amount of time (for example, if I opened terminal emulator and changed the colors, these would stay if I closed and opened the app again right away, but if I closed it for a while, say half an hour, and opened again, it would be back to default...)
I'm on a Galaxy S btw. If anyone has any insight on any of these matters, would be much appreciated!

Any progress? Would really like to use +4 GB files.

It is immpossible because of hardware limitations of the SD card And often if the file is big it just fail!

Not true, read the rest of the thread before u post! Its not a hardware limitation, its because Android uses fat32 as filesystem.

hello everyone,
I just wanted to check to make sure that there is no solution for this 4gb limitation with Android yet? I too have been looking for something besides resizing files.
thanks

I have ext2 on my external 32GB SDCard, just formatted it on my PC and put it in the phone, working without any problems. I just watched a full length 720p movie with DTS sound on my phone without having to re-encode the mkv
I'm using CM7.1 on my phone which auto-mounts the SDCard even with ext2. It won't work on stock ROM, but any kernel that has ext2 support should be able to read ext2-formatted cards but they might not auto-mount the sdcard.
On my PC I had to install a ext2 file system driver (google ext2fsd) for Win7 to be able to read the card when attaching the phone to the PC.

AbyssNote Kernel developer " angelom " pointed us solution for read/write ntfs for formatted usb stick and i apply it for sdcard and both works flawlessly !!!! Thanks angelom...
Some Tests:
** After mounting sdcard as read/write ntfs, camera app also can be able to record photos and videos to ntfs...
** Watching movies over 4 gb size is not a problem anymore. 1080p Mkvs with no lag at all...
** Most of the 3rd Party apps recognize ntfs formatted sdcard like it is fat32...
** Stock Video Player dont see NTFS so i use BSPLAYER LITE ( best for mkv on note ) OR MX VIDEO PLAYER !!! ( U can use ES file explorer to play videos with stock video player )
** Stock app like gallery dont see the files in ntfs sdcard... Quickpic app also doesnt work with ntfs formatted sd card...
PERFECT VIEWER CAN DISPLAY IMAGES AVAILABLE FROM NTFS SDCARD.... ( THANKS BROTBUEXE)
** You can use free apps like MyMusicOn or MixZing Basic to play music files which are in ntfs formatted sdcard...
** We have to repeat steps 4 and 5 after every reboot. Gscript lite app helps here so much with its shortcuts...
** We have to repeat steps 4 and 5 after using usb mass storage mode...
** Ntfs formatted sdcard also is recognized by windows when Gnote is using usb mass storage mode...
** I am getting very low transfer speed for small files in windows when Gnote is using usb mass storage mode... for big files it is as fast as Fat32...

Abyss V2.5 Kernel
32 gb class4 SDCard
How to: READ/WRITE NTFS
1- Flash Abyssnote Kernel - Latest Version : http://forum.xda-developers.com/showthread.php?t=1362424
2- Format sdcard to ntfs in windows and plug it to phone.
3- Power on phone and GNote will recognize ntfs formatted sdcard as blank sd.
4- Download ntfs-3g.zip from attachment...
4- Extract zip and copy " ntfs-3g " to /system/bin/
5- Reboot
6- Install Terminal Emulator from market.
7- Enter these lines in terminal emulator. ( insmod commands are optional for abyssnote kernel since they are loaded automatically but for other kernels u have to use insmod commands )
a- To mount ntfs formatted sdcard
su
chmod 755 /system/bin/ntfs-3g
insmod /lib/modules/fuse.ko
ntfs-3g /dev/block/mmcblk1p1 /mnt/sdcard/external_sd
vold
b- To mount ntfs formatted usb hdd or usb stick
su
chmod 755 /system/bin/ntfs-3g
insmod /lib/modules/fuse.ko
ntfs-3g /dev/block/sda1 /mnt/usb
vold
or create a newfolder named usb in internal sdcard
su
chmod 755 /system/bin/ntfs-3g
insmod /lib/modules/fuse.ko
ntfs-3g /dev/block/sda1 /mnt/sdcard/usb
vold
5- now goto settings-storage and select mount sdcard ( only for sdcard not usb stick )
6- now your ntfs formatted sdcard or usb memory stick should be recognized by system as read/write
7- After every reboot u have to repeat steps 4 and 5 !!!
8- To unmount usb hdd:
a- Run Terminal Emulator
b- Enter This line:
su
umount -l -f /mnt/usb
umount -l -f /mnt/sdcard/usb
c- now your usb hdd is unmounted.
d- You can safely remove it from otg cable.
** You can download "Gscript Lite" from market and create these scripts as shortcuts in your home screen so u dont have to enter line every time after reboot... ( Market - Free )
** Use "Autostart" app or "script manager" app to run script on boot... ( Market - Free )
** Use "elixir 2 widgets" app or " any cut " app to create a shortcut directly on home screen to settings-storage... ( Market - Free )
*** UPDATE 10-JAN-2012
I realized that after executing ntfs-3g , our ntfs formatted card is automatically mounted by the system even it says Blank SD in notification page... No need to go to settings-storage-mount sd card...
So if the blank sd message in noti. doesnt bother us, then no need to look for how to mount ntfs sd automatically... It is already mounted...
I use script manager to load the ntfs-3g script during boot and thats it... After boot i use my ntfs formatted card...
*** UPDATE 21-JAN-2012
While trying to get rid of blank sd noti, after running vold command, noti has gone, surprisingly...
No more " Blank SDCARD " or " Blank Usb Storage " in the notification bar.
Simply add " vold " command to end of script
...
After reboot "blank sd" noti will gone...
vold command remounts all storage.
Dont bother even settings-storage shows sdcard as unavailable since it is already mounted and recognized by the system...
Hope this helps,

Dear Friends,
Here is some info for read/write ntfs by fuse.ko module and ntfs-3g driver for GalaxyS2 but they failed to run in G-note when i try in terminal emulator...
http://forum.xda-developers.com/showpost.php?p=15001824&postcount=23
I hope someone may recompile fuse.ko for G-Note so we can use ntfs as read/write ... I dont know whether kernels has to be patched for fuse.ko support or not...
********** OLD INFO for READONLY NTFS as REFERANCE - OUTDATED !!!
I have managed to read ntfs for both ex.sdcard ( tested ) and usb otg devices ( not tested )... Needs ROOT ! Ntfs Read Only !
I wish some devs recompile ntfs.ko module as read/write so we can use all time ntfs formatted ex.sdcards...
Sdcard method is tested by me and i have watched 10 gb " last samurai " 1080P mkv movie with mx player flawlessly...
I dont have a usb otg cable so i couldnt test usb hdd or usb stick but i guess they will work, too. ( your feedback is needed here )

PROTOCHIP,
I carefully read your posts but I don't understand where ntfs.ko comes from. I used MySam Ed and AbyssNote kernel (I am on KL7 now) and I did not manage to understand where that ntfs.ko modules is. I saw your posts with angelom on AbyssNote thread but the question still remains.
Can you explain where it is from and if, for instance I could use it with another kernels ?
As I have ordered a 64 micro SDXC card for my toy, I really expect to be able to see films in HD with being bothered by file size. And if it is possible to have a read/write access to the card, it would be really amazing.
Thanks in advance for the upcoming info on the subject.

Dear The_Steph,
Actually i dont know where the file comes from but after flashing MySAM rom to phone, ntfs.ko is located in /lib/modules/ ... In case it is needed, i have enclosed the file here ... You can copy it to /lib/modules/ and try with other kernels... I tested it by Abyss but for ChainFire kernel and FM Kernel, i didnt test it...
My sdcard is class4 32 gb and watching Last Samurai as 1080p mkv from ntfs formatted sdcard is amazing... The mkv file is around 10.2 gb...
For ntfs read/write ; there is another module called fuse.ko and driver called ntfs-3g but as far as i know these modules have to be recompiled for our kernels...
Hope this helps,
Kind Regards,

PROTOCHIP,
It is not in stock KL7 ROM and does not seems to be in MySam too. I read the post you linked. I understand now a bit more.
As I am planning to move to XtraLiteRom from Cassie today, I will try to do some tests tomorrow using the ntfs.ko and above 4GB files. I'll reports afterwards.
As you stated, maybe read/write library can be recompiled for the SGN.
It it is possible it would be awesome. Hopefully, a master in modules compilation will see this thread
Edit: I hope I helped a bit posting reference to this thread in RiverSource kernel thread.

Really looking forward to development on this matter.

As planned, I did some tests this morning with my Cassie's XtraLiteROM v5 (stock KL7 kernel) as I have a spare 16GB micro SDHC card.
I formatted my card in NTFS and put it in the slot. Rebooted my SGN and got the message as my SD Card is empty. So i plugged my SGN to my PC to see what was wrong with libraires.
First point, as I use Multimount SDCard, my internal memory and external SD card are automatically mounted when my SGN is connected via USB. Which make me realised that even if librairies were not working, the NTFS formatted card can be read/written by Windows even if the SGN is not able to read it.
Once that seen, I tried to do your step by step tutorial (which was not working because I initially forgot fuse.ko in /lib/modules) and got the following error message:
insmod: init_module '/lib/modules/fuse.ko' failed (Exec format error).
So I created a /sdcard/ntfs-3g/ folder and put fuse.ko in it as I saw on another thread but it did not work. I rebooted my SGN and found that what was working the first time (automatic mount of SD cards) did not work anymore. Strange.
Looking for clues on Google, it seems that fuse.ko needs to be compiled for the kernel magic number to properly start (CL823206 for XXKL7). So, two cases: we are lucky that the kernel magic number was the same as angelom base (what a luck), or angelom compiled the fuse.ko for his kernel magic number (likely).
So my question is now, did angelom compiled the fuse.ko file for his kernel?
Next steps for me are to move my KL7 kernel to angelom's and to automate the SDCard mounting process (I'm pretty sure a script in init.d could do the trick).

Dear The_Steph,
Pls Follow the steps in the updated first post and the right files are also enclosed in the post. I guess u have to flash Abyss kernel... My Sdcard is now ntfs and even the camera app can read and write to it... Just woow... Now Watching 1080p Avatar movie... show off time !!!
Kind Regards,

Other than the ability to use bigger size files, is there any advantage of using ntfs ?
THere are the new 64gb cards . was wondering if there would be any benefit in using them in ntfs

Dear drgopoos,
Main purpose is to be able to use larger files than 4 gb, other then i didnt realize any speed improvements regarding to my short time tests... Forum User " The_Steph " got a new 64 gb SDXC card and he is starting to test it with ntfs i guess... He will kindly report back soon...
Kind Regards,

My 64 card has been ordered at Amazon and it is planned to be delivered to my house the 4th of January.
As the SGN does have a big enough internal memory to store all daily files such as applications, pictures and data, my only aim using this modules is to be able to store HD movies on it (always bigger than 4GB) as I mainly use my SGN as an HD PMP during my daily commuting. I don't really care about the rest since as I said eearlier, it cans be hosted in the internal memory.
I am currently doing some tests with an old 16GB SD Card before my big jump to the 64GB world
I have now tests to do with AbyssNote 2.5 kernel then
An aditional question, is you fuse.ko removed from /lib/modules each time you restart your SGN?

Dear The_Steph,
No, It is always in /lib/modules... I have several times restarted my Gnote and never copied fuse.ko... Weird...
Kind Regards,

PROTOCHIP,
I think this then because of angelom that kindly added fuse.ko and ntfs.ko in the /lib/modules
Moved to angelom's AbyssNote 2.6 kernel and did your step by step procedure. Everything is now working perfectly
Next point is now how to automate it to automatically mount the card at Android startup and unmount it when shutting it down.

Dear The_Steph,
Yeah these files must be related with the kernel itself... By the way, is abyss v2.6 released? I cant find it...
Kind Regards,

PROTOCHIP,
Did not look for AbyssNote 2.6 yet as I was working on automation.
BTW, I succeded in automation of launching script with autostart https://market.android.com/details?id=nk.bla.android.autostart.
Last point to do is finding the settings > mount SD card script line to finalise a complete NTFS formatted card mount script at start
Once done, I will create a CWM flashable file to ease the process.

I have voted this thread 5-star that it deserves. CHEERS.

Here's my experience so far using stock KL7 deodexed ROM with Abyss kernel 2.5:
0. Firstly, I have a 32GB MicroSD card and I have successfully copied a 10gig 1080p MKV video file to it and played it without any issues on my Note thanks to this thread. THANK YOU heaps.
1. Using 'Script Manager' app, I can auto-run the script at bootup. But I still need to manually go to settings - storage and mount SD for it to be actually mounted. Is there a command to do this also at boot up via the same script? or is there no other way to mount it?
2. I noticed that all the video files in the \sdcard\external_sd are not seen by the media scanner. So the videos do not show up in Videos app and my favorite video player which is Act 1 Video player. (it just goes by the media scanner indexing and has no option to specify folders manually) Is there a way around this? or is this a limitation that is unavoidable?
3. I have no issues with connecting it as mass storage to my PC using USB cable and can copy files without any issues or speed loss to my MicroSD card. Awesome. (I get 11MB/sec consistent write to my Lexar 32GB class 10 card)
Anyways, overall, I'm super duper happy. =)
But yeah, solutions for #1 and #2 would make it perfect.

Dear jakiman,
Thanks for the feedback...
1- We are all looking for a solution to mount automatically... At least in new abyss kernel V2.6, fuse.ko will be automatically loaded during startup so there will be no need to use it in scripts i guess...
Use Autostart app or script manager to run script on boot...
Use elixir 2 widgets app to create a shortcut directly to settings-storage...
2- Stock apps has problems recognizing ntfs files... We have to use 3rd party alternatives...
For videos i use mxplayer and bsplayer.. Bsplayer is much more smooth that make me shocked...
For photos neither stock nor 3rd party apps i tried could read ntfs files... So viewing photos from ntfs is still problem... i select the file with es file explorer and then choose gallery to show photo file from ntfs.... I copied all photo files to internal memory for a temporary solution...
3- My card is 32 gb class4 and that may be the problem for copying small files... For big files like movies i get 7 mb/s transfer rate with usb mass storage mode on windows7...

EXT3/4 support

Hi! Neither with StickMount or Nexus Media Importer can I mount USB sticks formatted as EXT3/4. Is this a kernel issue? If so, are there kernel modules availible for N7 stock ROM/kernel that adds this support?

Ther kernel definitaly supports ext4 as all Android partitions themselfs (cache, system, userdata) are formatted ext4.
Must be something else.
Are you getting any error messages? If yes, what are they?

No errors. Mounted folder in ES is empty (using Stickmount), Nexus Media Importer says it can't read the USB device...

Is the USB stick partitioned and the tools (sorry, never used them, so going go guess into the blue here) try to mount sda but the stick is actually sda1 - or vice versa?

Even the FAT32 partition gets named sda1. "sda" is never a partition in itself as far as I know

-> sda is the name of the device, the full disk name under the system, sda1 is the name of an SDA's partition.
ie:
you have an USB key, the linux system will know it as SDA device (disk).
if you create a partition, it will assign a number, 1 then 2 etc....
You can format SDA1 in VFAT and SDA2 in ext4.
PS: creating partition is a bit more complex, because there is primary and extended one, some FS are limited in size, some system require primary partition etc...

Stickmount is very iffy in 4.2 (works fine in 4.1.2).
I've read that Nexus Media Importer works in 4.2 but it is read only and as the name implies works only with media files.

That's what I meant, Linux also allows you to format sda directely, without any partitioning and Windows always does it with removables that way (it never partitions flash drives).

[Q] Sprint Galaxy Tab won't take any OS I try to install on it

It's kind of a long story... I got this tablet yesterday and immediately tried to see if I could install cyanogenmod on it (the stock OS is quite horrible). With every step, I faced challenge after challenge - there's an in-depth guide using Heimdall on these forums that gave me a lot of issues. In particular, the most recurring problem I had was that my Galaxy tab was never able to mount its internal SD card, which meant that installing cyanogenmod was pretty hopeless (the installer's not compatible with my tab). As time went on (I spent a LOT of time on this) I figured out that I could access the root of my tab using the adb shell command. Here, using parted, I stupidly formatted my internal sd card to an ext4 filesystem thinking that would solve all of my problems. This is where my real problems started though, because now my tab will not boot up completely no matter if I give it the original stock rom or a rom with superuser and root access built in or anything.
Everything I try either causes it to immediately go to the recovery menu and display a bunch of errors very similar to this: forums.androidcentral.com/samsung-galaxy-tab/222766-galaxy-tab-might-bricked-help-needed or just enters a boot loop with the glowing Samsung logo. I've seen miracles performed here, so I thought maybe I could try all the suggestions I can get before I give up.
Here is what I can do:
- I can enter download mode and interact with Odin.
- I can use Odin to install ClockWorkRecovery and I can boot into cwr
- I can copy files to and from my tab using adb, and I can use adb shell
- I know how to manually mount my internal sd card so I can install zip files.
- I can format my sd card to anything BUT the rfs filesystem it desperately needs
I'm willing to try anything. Thank you for reading.

Buy a 2gb microsd, only a few dollars. But a USB card reader. Also a few dollars.
Or sprint tab has no microsd slot?
Anyway, I thought internal SD is vfat/fat32. Not RFS.

Ok, through some kind of magic I got the stock+rooted+CWM rom to install and now it works correctly! my partitions look like this:
Number Start End Size Type File system Flags
1 32.3kB 1201MB 1201MB primary fat32 lba
2 1201MB 1700MB 499MB primary ext2
3 1700MB 1900MB 200MB primary linux-swap(v1)
I made these partitions myself. My fstab looks like this:
/dev/block/mmcblk0p1 /cache rfs rw
/dev/block/mmcblk0p2 /data rfs rw
/dev/block/stl10 /datadata rfs rw
/dev/block/stl9 /system rfs rw
/dev/block/mmcblk1p1 /sdcard vfat rw
/dev/block/mmcblk1p2 /sd-ext rfs rw
I have no idea what I did to make this work, but I guess it just does now...
So now that I have CWM and a rooted stock 2.3.4, how do you think I should install cyanogenmod? Part of me wants to use ROM manager...

I don't know why your internal SD is only 1.2G+499MB+200MB
That is total less than 2GB.
What happened to the remaining?
Best is you repartition your SD again.

I don't know the exact amount of storage I have in MB, so I just guessed. You know how when you buy a computer with 500gb of storage on it there is really less than that. If I were to guess, I'd say the SD card is about 1940-1970MB, but without any way of knowing I didn't want to tell parted that there was more space there than there actually was. In parted, you have to specify the amount of space you allocate to each partition, and I don't know of a way to see the total amount available.
So that being said, how do you think I should go about installing cyanogenmod? Thank you for all of your help so far. It's nice to have this community

Recognizing and mounting ext3 and ext4 partition on sd card

I have successfully created the partitions as ext3 but no matter what I do I just cant get my tmobile Note 4 to recognize it or mountit. I have a fat32 partition that it reads just fine...Ive tried stickmount and other apps meant to mount these file systems but none have succeeded, Ive searched everywhere I can think of and cant'find anything especially specific to the Note 4 any help would be appreciated

Put your SD card inside of your phone and reformat it there.
Settings-> General -> Storage -> Scroll down and you'll see "reformat SD card."

He's not trying to format his card, he's trying to get it to recognize the extra partition on it, probably for apps.
@op
Try the app link2sd on playstore and see if that works, report back.

Link2sd may work in its own respects but i guess i could have been a little more thorough expkaining my situation...im trying to run linux in a chroot enviornment and i can get it working but with limited space for my linux image. I need the support for larger files that the ext filesystems are capable of. So although link2 sd may be able to link the partition im not sure its going to do mr anygood unless after i run link 2 sd it makes tge partion visible and useable outside of tbe app

Oic so why not just format it as exfat which has no file limitation and use a proper kernel which supports it. I myself use exfat on my 128gb SanDisk.
