Unless you can isolate the problem to a cable or some other hardware
flaw that would be cheaper to fix, I'd recommend a new drive -
a.s.a.p.

Sometimes errors like that are bogus, but you can't count on it.  I
have a Seagate that was reporting 4294967295 bad sectors every 30
minutes until I retired it, but Seagate's stools showed that there
were in fact no errors on the drive, and that number just happens to
be 0xffffffff, so I didn't really believe it, but I also didn't trust
it - for two years.  AFAIK it's still working flawlessly....
