This problem has been fixed, thanks for suggestion from Tony of the UK.

Do you mean you get thje CASS? prompt when you turn the
machine on
without holding BREAK down?
If so, then the machine is not detecting the disk controller (that's why
it's not trying to read the disk). I'd check the tapewire that links the
CPU board to the disk controller board (I've had a lot of problems with
this cable!), then check the signals round the WD1793 chip.

Looking for diagnosis or URL with troubleshooting guide:
TRS 80 Model III with two mini drives.
Powers up, drives spin and do not stop.
Does not attempt read, no red drive light.
Cass? and Memory Size? Ok
