 I had an identical problem, although it was a GVP controller and a Priam
drive. As it turns out this is an easy one, at least for GVP controllers.
Since SCSI deals with blocks only you can reduce the number of heads that
you tell the controller exists and increase the BlocksPerTrack. Somewhere
(AmigaDOS?) these numbers are multiplied out to give a SCSI block number.

For instance, say you have a drive with 15 heads and 7 BlocksPerTrack.
Just turn this around and tell the controller, presumably in the MountList,
that your drive has 7 heads and 15 blocks per track. Have fun.
