[TIP] the JB leak comes with proper exfat support.

[shadowofdarkness]

After finding exfat files in the filesystem I formatted my external sd as exfat and the phone recognized and used it with no problems.

I am currently backing up my internal sd card to do the same


Note doing a format from storage settings still uses fat32 so format the card in a computer or unmount the card in the phone and use a adb shell to run

mkfs.exfat /dev/block/mmcblk1p1

after backing it up since you are formatting.

Will backup my sd and try it, have you experienced any problems?

no problems with external but don't do the internal it didn't work for me it's still hard coded for fat32

I don't know if you looked in the vold.fstab file but I noticed this code in there while I was looking at how to swap internal SD cards: -

# internal sdcard
{
ums_sys_path = /sys/class/android_usb/f_mass_storage/lun0/file
secure_format = enable
discard = enable
supported_exfat = disable

The last line there sort of indicates that support is there but someone needs to try adjusting it I guess to test

It may be possible but I am not going to worry to much especially since I need to leave one as fat32 or else lose most CWM functionality since it doesn't support exfat.

if you format the card to exfat, does it work properly if you connect the phone in mass storage?

I had no problem using mass storage with the exfat formatted card. That is on my laptop that is running Linux with the exfat fuse modules.

but on windows that would not work, it does not support exfat, right?

of course it would, Microsoft created exfat.

I'd love to switch to exFAT for its advantages, but I just know if I switched to it, I would have to go back to FAT32 when I use CyanogenMod, namely due to the fact that you have to get patent licenses and crap from Microsoft to be able to implement exFAT, which I assume Samsung must hold so they can use it on their phones and TVs.

What we really want is MTP fully working on Linux and for the internal and external SD cards to be in EXT2/4 or something like that, and then it would keep both Windows and Linux users happy and we would have better file size support and performance.

That's my 2 cents.

I know that would be great if it happened. I know before I realized exfat worked I had mine ext4 and used a app to mount it but it had little drawbacks that this native support fixes.

Plus now I can connect my digital camera to my phone via OTG since it has a 64GB sdxc card that uses exfat which is another major plus. I always hated being out and not able to get my photos off it and passed out to other people until I got home and to a computer.
