Title: It's not dead :-)
Post by: A4000_Mad on October 31, 2008, 12:14:20 PM

Hi Guys,

A computer friend who isn't into Amigas gave me an IBM Ultrastar 18.2GB 68p Ultra3 SCSI drive that he'd found amongst his stuff. It fitted straight onto my CSPPC and I thought I finally had a nice drive for running OS4 in my A4000.

However, when I switch on it doesn't spin up. Any chance a wrong jumper setting could stop it spinning up, or is most likely to be dead?

Model of drive is DDYS-T18350

thanks

Those Ultrastars have a spinup jumper indeed. It is on the jumper block underneath the drive PCB if I remember correctly.

EDIT: Read the manufacturer docs (http://www.hitachigst.com/tech/techlib.nsf/techdocs/85256AB8006A31E587256A78005A3610/$file/ddys_sp21.PDF) where to find it (but ususally that's easy, all the jumpers should be labeled).

you should also know that the CSPPC scsi controller is pretty anal about termination. You should have active terminators on the both ends of the chain.

Thank you very much guys :-)

I put a jumper on 'ENABLE AUTO SPIN' and I'm now booting into OS4 :banana:

:cheers:
