I had a strange experience too, while installing a Seagate Hawk 4 drive,
but eventually got it working.
I installed it as ID 2 unterminated, just as you did. My IBM startup
drive (ID 0) was on the end of the chain. I used the SCSI jumpers on
the 68 to 50 pin adapter and did not use the ones on the front of the
drive (I don't know if the Medallist has a similar configuration). This
is what they recommend.
When I first tried to use the Apple tools, I got the usual 'this drive
not recognized, not supported' messages. I didn't have much luck with
Hard Drive Tools either.
Silver Lining Pro recognized the drive and appeared to install a driver,
but would not low level format the drive. The drive passed the basic
media and memory subsystem tests, but in the formatting, it would go
beyond the 'allotted' time it would normally take (after everything
appeared to format normally) and then report errors and refuse to
partition the drive. In fact Silver Lining Pro crashed when I tried to
move the pointer over the partition pie chart image.
But ... after messing with Silver Lining Pro and attempting to format
and install a driver, the Apple Drive Setup utility was then able to
recognize the drive. So, I did a low level format with Apple's Drive
Setup utility, followed by initialization. However, Drive Setup
wouldn't let me partition the drive into sections as I wanted. So ...
... back to Silver Lining Pro. It was now happy with the drive and
allowed me to partition it into three partitions (over-writing the
single partition, and the Apple driver with the Silver Lining driver in
the process) and it seems to work fine now.
My success may or may not have been dependant on the fact that I used SL
Pro. I don't know. It may just have been the back and forth nature of
the process, and so perhaps will work with other products. Very silly,
if you ask me, but the information here might help you and the many
others who are struggling to use 'unsupported' third party drives on
