[comp.sys.ibm.pc.misc] Using 2 hard drives in an XT

mikec@mullauna.cs.mu.OZ.AU (Michael CIAVARELLA) (03/26/91)

Could someone please give me some advice on getting two hard drives to work
off a single controller in an XT clone?  my hardware configuration is:
		640K 2xFDD, serisal paralletl etc.
		2 * Miniscribe 3650 drives (40mb formatted)
		1 * Hard drive controller
		Phoenix BIOS

I've tried just about everything I could thing of - changing drive seect
jumpers, using a twisted daisy chain instead of a flat cable (I have both)
and basically every possible combination of these.  

Both drives start up OK, but then one sounds like its trying to seek past
the last track, and then I get all sorts of problems - but it always ends
up with Disk Boot Failure.

Both drives work fine when they are the only drive on the controller - and
I have tried this with another controller, so it doesn't appear to be a problem
with the drives or controller themselves - just the configuration of these.

For what its worth, the controller I am using is a Data Technology 5150X
which is an ST-506 controller.

If anyone knows how to run both drives off the one controller, I would greatly
appreciate knowing too.

Replies by e-mail, and I will summarise to the net if anything interesting comes
up.  


Thanks,  Mike
