hmm. I bet the drive labels are screwed up. For fun, stop the array,
load up fdisk on one of the disks and type 'o' - that should make new
dos disk labels.

it's something I ran into, but this was a long time ago, so the above
info might be out of date./

so make new drive labels, repartition and recreate the array.

see if that doesn't fix it.
