First, create an image of your disk NOW if you need anything that is
still on your disk. Next time create an automatic backup, so you don't
depend on such tools.

badblocks can use a read-only mode and also a non-destructive write
mode. Be aware: Your disk can fail at any time, don't do more
experiments without a backup than needed.
