The drive on
http://www.zimmers.net/cbmpics/deieee3.html is what I'm looking
for.
I've had a chat to my dad who's said that the technician said it could be
one of 2 things.
1. The head moves & is attached to a wire. A connection in the wire could be
faulty.
He said that fixing the wire was niot an option for some reason or other but
I guess we could replace the head. Can I replace the head with one from a
different model? If so, which are compatible?
Err... This worries me. How can he not know if the head connections are
open-circuit (they are not hard to test!). Why can't the cable be
replaced (I've resoldered connections inside drive head assemblies many
times). It's a lot easier to replace the cable (if that's the problem)
than to replace the head, since if you do the latter you'll need the
right alignment disk to set it up.
2. There are 3 main chips on the mainboard which seemed to be running hot.
The guy replaced 2 but didn't have one to replace the 3rd.
They do. In fact my 8250LP has factory-fitted heatsinks on some of the ICs...
I hate to say this, but that 'technician' sounds to be terminally
clueless. I fail to see how he can't tell whether it's a fault on the
mainboard or an open-circuit head connection on one of the drives (First
question : does one drive work correctly and the other fail, or what?).
Has he done any meaningful tests at all?
