This shouldn't have caused hard disk drive damage; modern hardware
should be smart enough to shut down safely on power failure.

I haven't used badblocks, but suspect that the hard disk drive
electronics is clever enough to hide damage and relocate bad sectors.
The S.M.A.R.T. electronics will still know they are there, though.

I have had some success recovering disk errors following the guidance here:
