debugfs -- something to know

as usual, i've deleted important files. i've deleted penguin photos.
searching up yahoo and google, i've tried some tools for ext2 files, and i've seen some comercial software.

finally, i see an article w/ 'debugfs' to debug the file system: debugfs -w , then lsdel to list deleted files, then use stat...

unfortunately i get error w/ opening the device, my usb storage key, but it's pretty neat thing, the debugfs. i didn't know it before. should get to know it well...
