     601 ~means "I don't see it at all." It is reported when there is
no response from the drive. I would reseat the power plug and jumpers
(there should be no terminating resistor in B:). The signal/data card
edge connector is probably OK since A: works (it is after B: on the
cable) but clean the contacts and reseat anyway. You could also check
for continuity across the cable.
