I just installed a 5.0 ROM from having been on 5.1.1 stock and discovered the ext4 formatted sdcard is not being mounted. It seems ext4 may not be natively supported in 5.0.
Is there an app I can install that can fix this? I found various "sd card fixer" apps but none of them worked. I also found a script on here but it seems it may not be fully functional (pls correct me if I am wrong).
Any help would be greatly appreciated, thanks.

Hi, is there a way to format the Internal SD of a Vibrant as ext4?
I'm running Team Whiskey's Bionix-V 1.3.1. The Internal SD mounts as vfat.
The main reason for asking is because BeyondPod stops working every day or two because of a read issue on a podcast file. The recommendation is to do a reformat on the SD.
(can't post a link because I'm a new user)
My thinking is that if I have to reformat Internal SD anyway, I might as well make it ext4.
Thanks.
Doesn't work well
I tried doing this over the weekend. This worked poorly, I think because vold on Froyo can't see ext4.
I was able to mount the internal SD over USB to my Linux box. After copying the files off the vfat partition, I reformatted it as ext4 (using tools on the Linux box).
vold.conf and vold.fstab were modified not to try to mount /mnt/sdcard, as it wasn't able to see ext4 anyway. I put in a file in /etc/init.d to run the "mount" command for /dev/block/mmcblck0p1 to /mnt/sdcard so as to do the manual mount.
Permissions were an issue; the vfat mount was effectively mode 777, and I tried doing a chmod on the ext4 filesystem to the same effect.
Some apps started to work better, but, the original purpose of the exercise -- to get BeyondPod to work on ext4 -- did not work out. The operating system didn't seem to know that the SD was mounted; in Settings, the OS kept thinking that the SD wasn't mounted at all (it probably knows through vold) and apps such as BeyondPod probably takes its cue from that, rather than looking to see if its files are present at the expected mount point. I'm sure other applications will have similar issues.
After I realized that Froyo was not going to recognize ext4 through vold, I rolled back to vfat. I guess I just have to wait for a Gingerbread on the Vibrant (e.g., CM7 finalizes for the Vibrant, or the recent 2.3.3 for the international Galaxy gets into Team Whiskey's hands).
Hey there,
I'm using a ext4 formatted External SDcard on CM10 (4.1), by using the modified sdcard binary that can be found in this forum.
However, in CM10.1 the binary no longer works.
I need the ext4 format for supporting >4GB files.
Any tips?
Thanks

Hi,
Thanks for your kind help.
I was flashing my wife phone (a Samsung S3 i9300) with slim bean 4.3, i installed CWM, root it, do a titatium backup, everything great, i install from the sd card Slim Bean, everything just great, until i see that the android was not mounting the sd card, i went back to cwm and i can see the sd card with all it content when i choose install zip from sd card, but i can't mounting in android.
So using the adb througt linux, i could upload the cyanogem mod last rom and the gapps file i went back, i install it throught cwm and everything just great but i still can't see the sd card in android, i'm not sure if i do something wrong in cwm when i was trying to mount the sd card to upload the flash files from the computer to the phone.
I never see an error like it.
BTW my wife gonna kill me please help
I just put show log and i have the follow errors:
Can't Partition non-vfat: datamedia
Can't Partition non vfat: ext4
Can't format unknown volume: /emmc

I know whats happening, i don't know why the sdcard move to /sdcard/0 so all my files and folders was on /sdcard/, of course i cannot see my files, and i thoungt the sd card was no mounting my fault.

I am using a stock ROM for the Azpen A727 and have been trying to install Link2SD on it. It is rooted using King root and that seems to be working OK. I partitioned a 15Gb sdcard as 7Gb ext4 and 8Gb fat32. When I open Link2SD I see the prompt for picking the file system so I select ext4 and it says the script was created so I reboot and the same thing happens again. I tried ext3/ext2 but when I try that Link2sD says "script failed to mount. Invalid argument". I have setup Link2sd on many other android devices without any problems but this Azpen stumped me. How can I get Link2SD to work?

I have a 128GB microSD installed in this phone formatted for exFAT. I would like to format it for ext4. First, will the OS (Pixel Experience) recognize and mount it, and second, besides eliminating permissions issues, what other advantages (or disadvantages) would this give me? I only use Linux OS on my computers so reading the microSD as ext4 on my PC is not a problem.
For that matter, is there something better than ext4 I should consider?
Best to format as fat32 (default) for overall usability. You will find that almost no roms support ext4 file system on sdcards. I know Havoc OS does because I have a small 32gig ext4 partition on my sdcard. While most roms dont support ext4 on sdcard the bigger problem is that recoveries (twrp) don't support them. So no backups, no flashing roms, absolutely no access to your sdcard.
Really there is no reason to change the format of your sdcard. If you really want something besides fat32 then exfat is the only real option but again there can be issues where some roms and recoveries still wont support it.
