Hi there,

I recently found a DDYS-T18350 18.2 GB hardisk made by IBM. This
harddisk uses a SCA plug to connect to the SCSI controller, but the
build-in controller of my Mac 7300 has a 50-pin connector. Can I use an
adapter (SCA to 50-pins) to run this harddisk in my Mac? Do I have to
install the HardDiskToolkit as well? I am unsure if this harddisk is
supported and I could not find any information about this.

Thanks in advance. Greetings to from Germany.

Ok, now I finally bought an SCA/50-pin adapter and plugged it together with my hard disk into the SCSI chain. When I boot the computer I can hear the drive spinning up, but I can not hear any movements of the heads like other hard disks produce them. Is it broken or is it jumpered wrong?

There are jumpers for the id on the adapter. So which jumpers should I use? The jumpers on the hard disk or the ones on the adapter? I realized that the jumpers seem to combine: When I jumper the adapter to id 2 and the hard disk to id 4, the "System Profiler" prompts that the connected hard disk has id 6.

But the "System Profiler" says also that the drive is not ready. Harddisk Toolkit prompts the same and I also tried one original and one hacked DriveSetup, but it can not see the hard disk. I tried several positions and ids within the chain.

Could it be a termination problem? I have two working hard disks already connected to the controller and the last hard disk seems to terminate the whole thing. Between the first and the second disk is a small black box attached to the cable. Is this a terminator? I moved this black box to the end of the whole chain, but then the computer won't boot.

So i thought it would be the best solution to plug the new disk between the two existing disks. But it changes nothing. The SCA-drive seems not to be ready.

Oli.
