No, I was wrong. According to the manual, the
'ready' signal depends on a
clock signal that comes from a special track on one of the platters,
picked up by a fixed head. The basic procedure if the drive won't go
ready is to look at the output of this head's amplifier, if that's
missing/incorrect to troubleshoot or replace the read/write PCB (and if
that doesn't get it back, then the fault is inside the HDA and is not
field repairable). If the output of the clock head amplifier is OK, then
therer's a fault on the control PCB.
Thanks, it's enough to get me started. I'll let you know if I'm
unsuccessful.
