Could someone please tell me why fitting an ESDI Hitachi DK515-78 to the
spare disk line of an MD21 controller should result in that disk not being
visible to the system (ie. to format).

The disk is set to drive the next drive number after the existing
Micropolis 1558 and a new kernel has been built expecting two drives.

What are we doing wrong ? Is there a hidden jumper on the MD21 ?  Are some
ESDI drives so incompatible ?

Any help would be gratefully accepted since we need the disc space and our
funds don't stretch to a new SCSI box.  (We have the data for foramt.dat
once format sees the drive !)
