please post dmesg!

Be aware that some disk drives do the wrong thing.  Western Digital desktop
disks, for example, don't simply remap a sector when they find a bad one,
they sit there scrubbing forever trying to reread the data.  WD calls this
a "feature" and their server-quality WD disks that cost more don't do this.
It makes use of these disks impossible in a raid array.  Seagates and
Maxtor desktop drives to my knowledge don't do this.
