Thanks for looking anyway. You never know.
How is the Fujitsu drive connected to the Mac? Via the JackHammer card, via the Mac's external SCSi port or via another SCSI card?I figured I'd fiddle around with my Jackhammer. Tried out a 15k RPM SCSI drive. Was insanely fast. Funny watching it format and then create 16 2GB partitions.
Unfortunately, I discovered that so long as the Jackhammer card is installed, my Fujitsu drive won't mount any MO disks. I even tried erasing them with FWB HDT and using the FWB driver, but no go.
There is a list of specific MO drives in the manual that it says it's compatible with, but I was very disappointed to learn that it won't work with my MCR3230SS Fujitsu.
It is good to eliminate the obvious possible causes. Thanks for this. I have a couple of SCSI Fujitsu MO-drives (only up 640MB though). I must how they behave in my IIfx with the Jackhammer card.@ArmorAlley It's a 50-pin device installed in a Fujitsu external case connected via a 50-pin Centronics to 25-pin cable to my Mac's internal SCSI bus. It is terminated. I've tried to both with an active inline terminator, and by using just the built in self-termination on the Fujitsu drive itself (and then again both.) It is the last device on the SCSI chain at ID 6, per the drive manual's recommendation. It is the only device other than my internal HDD at ID 0, which is terminated.
I have also taken the drive out and connected it directly to the JackHammer's 50-pin connector, configuring the terminators for 1x internal, 0x external devices. Does not work.
The Fujitsu drive works perfectly fine until the JackHammer card is installed. It merely has to be present on my NuBus for the Fujitsu drive to stop working on my Mac's internal SCSI bus.
It works fine on other Macs. I've tested it on my IIfx and on a Centris.
