Re: Doug's questions about the Supra controller for the A1000 and SCSI IDs ...

Sigh, this is getting tedious.  I'll repeat the instructions for the LAST
time.  I hope he READs these this time.

Set the SCSI ID jumpers on the drive to something OTHER than 0.  Do NOT set
the ID to 7, because the Supra 4x4 for the A1000 has 7 as its ID.  The reason
to set the drive's ID to other-than-zero is to NOT usurp the first 6 or 7
cylinders for an autoboot partition.

Run the Supra Formatter (and you better be running at least version 5.1; 5.3
is preferable), specify the ID to which the drive has been set, and let it do
its thing.  Specify FORMAT but do NOT specify the MAP option, let the drive do
its own verification ... embedded SCSI drives are supposed to present a
perfect media to the host, and the surface checking performed by the drive's
built-in controller will do a far better job of checking and bad-block sparing
than the present host software.  This process will take about 20 minutes for
the 3280 (280MB) and about 30 minutes for the 3380 (380MB).

Reboot.

Re-run the Supra Formatter, respecify the ID to which the drive has been set,
and THIS time only do the partition info ... takes but 1 second or so.

Reboot, and assuming the SupraMount program is executed in the startup-sequence,
then the drive is automatically mounted and ready for use.

These procedures are for the Maxtor XT3280 or XT3380 drives, and work fine on
ALL my systems and the systems I've built and/or put together for others.
