Hi -

I'm searching for file system corruption tool, say it inject disk-errors
multiply owned blocks etc. Later an integrity scan process (like e2fsck)
verify on-disk layout and fix these errors.

I'd like to read/understand such tools before writing one for an proprietary
on-disk file system.

Do we have such tools for ext{2,3,4}fs ? Thanks for any help or pointers!
