Lo mejor, o incluso lo único que he encontrado hasta el momento es
ext3grep[1], pero del tuto[2] que seguí para recuperar unos datos
perdidos y que tuve un 60% exito, te dejo este texto:

"The most frequently quoted passage comes from the ext3 FAQ itself:

Q: How can I recover (undelete) deleted files from my ext3 partition?

Actually, you can't! This is what one of the developers, Andreas
Dilger, said about it:

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.

However, this is not necessarily true. All information might still be
there, also the block pointers. It is just less likely that those are
still there (than on ext2), since they have to be recovered from the
journal. On top of that, the meta data is less coherently related to
the real data so that heuristic algorithms are needed to find things
back. Every time a file is accessed, it's Access Time is changed, and
it's inode is written to disk, along with 31 other inodes that reside
in the same block. When that happens, a copy of that block is written
to the journal. Therefore, if your partition isn't too large compared
to your journal, and if you at least recently accessed the files you
want to recover, you might be able to recover the block pointers from
the journal."
