Probably, your JAZ drive (/dev/sdc) was partitioned with another SCSI host
adapter (most probably an NCR53c7,8xx). The adaptec host adapter won't be able
to handle a SCSI mapping different from its own.
A adaptec mapping would be
255 heads, 63 sectors, xxx cylinders
like on /dev/sda and /dev/sdb
Remedy:
Repartition the JAZ drive with the adaptec adapter. THE NCR (and most other)
host adapter will be able to handle it.
