But that many bad blocks?  On three out of four disks?  This is very
unlikely.  To recap:

I have one Seagate Barracuda that reads and writes at about 9 MB/s.  I
have another Seagate Barracuda, and two IBM drives, that read at
9 MB/s but write at 1.2 MB/s.

This is not mission-critical stuff, really.  It's just a very
interesting problem.
