The disk is an IBM 73 G. drive:

sd0 at scsibus0 target 5 lun 0: <IBM-ESXS, DTN073W3UWDY10FN, S27P> disk fixed
sd0: 70006 MB, 36703 cyl, 6 head, 651 sec, 512 bytes/sect x 143374000 sectors
sd0: sync (50.00ns offset 16), 16-bit (40.000MB/s) transfers, tagged queueing

Controller is a Symbios (Tekram):

esiop0 at pci0 dev 12 function 0: Symbios Logic 53c875 (ultra-wide scsi)
esiop0: using on-board RAM
esiop0: interrupting at irq 11
scsibus0 at esiop0: 16 targets, 8 luns per target

It's quite old.  The BIOS is from 1998.  One noteable thing I had to
do was configure the BIOS not to scan for the IBM disk.  Otheriwse,
the BIOS hung when it probed the disk's SCSI id.  Once I made this
change, the disk worked without any problems until the one which
started this thread.
