I suppose there are only a limited number of places inside the drive
that it could have come from...

Do you know if it's an 200E-series drive or a plain old 200 series?
Capacity seems to be dictated by number of heads (which you can count
with the lid off!), but the E series drives were capable of more
cylinders than the others...

Hmmm... not sure, but I presume the software expects the bridge board to
be present as it'll likely look for the drive geometry stored on the
first sector of the disk, then issue a vendor-specific command to the
bridge board to tell it the capacity of the drive that's connected to
it. That's not going to work in SCSI-land...
