Will the adaptec allow you to put the drive on a target that does not
do bios translation?  You would have to boot from another drive or floppy
to get to it.  Did you use bios translation on the ncr?  I am pretty 
sure I was able to use the actual drive geometry with my "dedicated"
boot drive on the ncr.

Probably the best way to move the disk is by doing a tape backup and
restore of some kind.
