I thought this might help: (copied from jwalanta.blogspot.com)
If you have broken ext2/ext3 filesystem, these two commands can be
your lifesaver. Atleast it brought my friend Abish's HDD 'out of coma'
;)
He had his important files in an ext3 filesystem which wasnt being
mounted. It turned out that it had its journal broken. Did everything
from disabling the file system's journal to trying out alternate
superblocks. Even tried to convert it to ext2 format. fsck.ext3 didnt
seem to repair a thing and hacks using tune2fs also didnt turn out
good. We were on verge of finally letting go of data and formatting
the hdd.
Then i found debugfs. The man page reads,
debugfs - ext2/ext3 file system debugger. The debugfs program is
an interactive file system debugger. It can be used to examine and
change the state of an ext2 file system.
Surprisingly debugfs seemed to list the files and folders of the
filesystem. Cool enough, it also has a tool called rdump which
recursively dumps a folder to another mounted disk.
So after invoking
# debugfs /dev/sda1
debugfs: rdump /home/ /mnt/externalhdd
and all the files were dumped to the external hdd safely. Simple, yet awesome!
