Subject: Upgrade ST-02 to 1542B => re-partition drive?

I used MS-DOS 3.3 fdisk and format to partition and format a Wren IV
with an ST-02 SCSI host adapter in a 12 MHz 286 machine. The partitions
were C (boot), D, E, and F. It worked fine.

After moving the disk drive to a 25 MHz 386 machine I tried booting with
an Adaptec 1542B adapter. The SCSI bios found the drive (id 0) but
could not find the system files. A boot from floppy in A: was ok and 
DIR C: found everything just fine. However DIR D: (also E: and F:)
reported partitions not found (or non-existent or whatever the word is).

1. Is a SCSI drive sensitive to the host adapter (or the computer)? If so, why?
   But the controller (where really low level stuff happens) is on the drive!
2. Do I really have to re-partition and re-format the drive?
3. Or is something else causing my problem?

Thanks for any help.
