Disk drives are very reliable but they do occasionally fail.  That is
one of the reasons that important data should always be backed up.

If you have connected it to another machine and it is still not
accessible then it seems likely the drive is broken.  It may be that
your data is not recoverable.  I don't know whether there are any
commercial organisations that specialise in recovering data from
broken disks.

I don't think that is likely.  When your tv breaks you do not assume
that it has been hacked so why suspect that when the computer breaks?
To physically damage a drive by hacking into the server would be very
difficult if not impossible.
