Root sd-ext3 to sd-ext4 question...

Can I just into my recovery and drill down to the partitioning function and perform a "EXT3 to EXT4"?? Will I need to copy my sd card to my computer and replace files to sd card once the EXT4 has been created? My ROM does support EXT4...:)

I don't know about that, as I have myself gone into recovery, and upgraded from ext 3 to ext 4 twice with not so much as a hiccup?:confused:

Edit: but better safe than sorry to make a nand!!

Hey Mikey! Yeah, I did do a nand bu then I went ahead and copied my sdcard to laptop BUT as it turns out, I don't think I need to copy anything back! After the upgarde to EXT4, I toggled the USB-MS and all the sdcard was still there! I rebooted and did a terminal emulator a2sd check and it 'sees' the EXT4. So, I guess I'm good to go...:o

EDIT: so, I'm a bit confused with what ocnbrz posted about the sdcard being formatted??? Seems that IF that were the case, I wouldn't be seeing the 'Removable Disk' and all its contents?

See this
I knew I had this "issue" before...look at post 226:)
 
As you found out, upgrading from ext3 to ext4 does not format your sd card. It's a one way street though, so if you ever decided to go back to ext3, you would need to reformat your entire sd card. I don't see much reason to do so though...the new underworld v8 kernel supports ext4 with sense roms now, and with a havs and nohavs version, it should play pretty nicely with everybody's phones.
