| ext3 is an extension of ext2. Basically, it is just ext2 with added journaling, therefore, if you have a utility that works for ext2 it will most likely work for ext3 as well. If you are concerned about doing that, ext3 is compatible with ext2 in both directions, so you could just do the following:
1) unmount ext3 partition
2) remount partition as ext2
3) do the undelete
4) umount ext2
5) remount as ext3
But in reality, you should just be able to run it even mounted as ext3. |
