John - Since you have a Disto HD host computer adaptor, you are using either a
SASI or a SCSI interface to your MFM drive.  (MFM and RLL are analogous to
single and double density on a floppy drive, and can be used with SASI, SCSI,
506/412, and other interfaces, even though some mail-order ads imply otherwise.
SASI/SCSI define the electrical interface and commands used on that 50-pin bus
between the host computer adaptor and the drive controller.)

To check which version of the driver you are currently using, do an "ident -m
cchdisk", and note the CRC reported.  If it is $A1199D or $A50917, then you are
using one of the SASI drivers.  If it is $B7AA8D, then you are using the SCSI
driver.  If it is none of these, then there have probably already been some
patches applied, and you will have to give us a few more details about the
equipment in your HD setup.

Good luck... / Ken
