Solution: The disk had been formatted by a different operating system
(NeXTSTEP) for bock sizes of 1024 bytes. SunOS uses 512 byte blocks and cannot
recognise 1024. Re-formatting disk with another tool such as the "scsifmt.exe"
program which comes with Adaptec's EZ-SCSI suite for DOS will re-format the
disk with 512 byet sectors. The disk can then be attached to a SunOS machine
and partitioned, etc.
