On bus 1 the drives are identical! Here they are:
% </proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 01 Lun: 00

The Seagates are Cheetahs, 10000 rpm ultra-wide ones... There are two
of them on bus 1 and the first one on bus 0.
How can I check their configs? The manual doesn't say anything.
