Yes, in order to ensure that ext3 can safely resume an unlink after a
crash, it actually zeros out the block pointers in the inode, whereas
ext2 just marks these blocks as unused in the block bitmaps and marks
the inode as "deleted" and leaves the block pointers alone.
Your only hope is to "grep" for parts of your files that have been deleted
and hope for the best.
Cheers, Andreas
