OT: Hard drive warning at boot time

One of the lines you listed was the "reallocated sector count".
Basically, when you buy a 500G drive, it really has more space than
that.  Some of the sectors are reserved and not reported to the system.
When the drive detects a bad sector, it relocates it to one of the
reserved sectors.  Once it has relocated a certain number, it reports
the drive as failing (possibly because it is out of reserved sectors to
use).

Given there were a bunch of reallocated sectors, I'd replace it as soon
as possible and then destroy it.
