Sometimes I've seen when a hard drive gets old and the head movement 
mechanism is worn the drive can have problems properly locating the head 
over track 0. I've also noted that sometimes even when it can find track 0 
it couldn't read the mbr. If this happens because of a bad spot has 
developed in the magnetic media there's nothing at this point that can be 
done. If it's just worn head slop sometimes you can write out a fresh mbr 
and use it for a while longer, but the problem will return worse later.

Using smartmontools and smartctl test/diags to get a test dump from the 
drive can be useful at times to decide if replacement is warranted.
