Drive Settings (DIP switches)
To set up an MO drive for use on your Amiga, you need to set the following
options using the MO drive's DIP switches:
- Set the SCSI ID to one which is not currently in use.
- You may need to set the device type to "direct access",
if your SCSI controller driver is old or badly written.
- Set "Macintosh mode" to off. I don't know what this setting means exactly,
but my drive works okay with this switch off. I have not tried it when the Mac
mode switch is on. According to Fujitsu: "Because of the differing ways that
both Apple Macintosh and PC hosts respond to the status of the drive, set this
switch accordingly. Mac mode ON will disable the 'UNIT ATTENTION' reporting on
power up and media change."
- If your drive supports SCAM (which I believe stands for SCSI Configured
AutoMatically), disable this feature.
- Set the termination depending on whether your MO drive is the last device in
the SCSI chain. If it is last in the chain, you may want to use an external
active SCSI terminator; this may be necessary if your SCSI chain is very long.
- You might need to disable the write-back cache. See
About the Write-Back Cache for more
information.
- Set the verify mode. When disabled, the speed of write operations is improved
by approximately 50%, however data integrity cannot be guaranteed. The
improvement when using LIMDOW media is about 100%. I recommend
that you always enable verify mode.
