Use ext2/3/4 on SD card as data partition FS

[Guest David Horvath]

Hey,

I was just thinking if i can use ext filesystem as the data partition. I Use Ubuntu, i trust ext, but not fat. Its ancient.

Thanks,

David

You can most likely create a symbolic link from the /data to the /sdcard or the folder that represents your ext partition but I think when you unmount it then it will cause a problem and will end up crashing the phone

And I agree with your about fat, I hate ntfs more, its a pain in the backside and I always need to boot into windows just to defrag it (which has turned to impossible as ive got rid of windows lol I never win, I did try a vm but it seems too underpowered)

WOOO HIT 300 POSTS!!!!

EXT2 is older than FAT32 but you have a point re EXT3/4 as they are journalling file systems and therefore more robust. However whether they are suitable for SD cards is a matter for debate - journalling introduces extra write cycles which will reduce the life of your card.

Personally I have never had an issue with a FAT32 partition on any memory stick so more than happy to use it on my Pulse.

I assume you mean /sdcard, not /data (the 'data partition' which is yaffs not fat). I'm fairly sure the old (eclair) version of vold supported ext2/3, but the froyo version is totally different and does not, so you would either need to mount it manually and set the environment variables that tell it the card is mounted or add ext2/3 support to vold. There would be features of android that would not work.
