and they both seem to be

   dead, Ive
replaced the controllor card check the dips,
 checked power output, it seems here in Austrlaia these drives are almost
 impossable to get a hold of...... 
I have schematics for these drives (in the IBM O&A TechRef) and the Tandy
instructions for aligning the single-sided version. So I think we can get
them working.

You say they're 'dead'. How dead? Why you access them, does the motor
start. Does the spindle rotate? Does the head carriage move to track 0
when you first boot up the machine (turn off, move the head towards the
spindle, turn on). Does the LED come on?

Or do they seem to work, and go through all the motions, but give you
data errors?
