Interesting... according to all these responses, I should be able to use
this hardware.
For reference, I'm not using newer drives. This is all second-hand
equipment.
I've got a Mylex DAC960PD (Fast Wide controller) and some older-looking HP
SureStore 2000S (C2940) Ultra Wide drives. I've tried multiple cables and
multiple terminators, both active and passive.
Basically, tho, none of the drives work. The diagnostics for the DAC960PD
indicate a "cable error" that has to do with parity. This only occurs
with a device plugged in. No combinations of just cables and terminators
will cause this to happen.
Unfortunately, I don't have any known-good 68-pin SCSI-II drives to test
with. Does anyone have any ideas where would be a good place to go next?
