#dead floppy drive

Most likely cause, once you mentioned storm, is one or both of the CIA chips.
If swapping them makes the drive behave, then that is the trick. If they both
got fried, you may have to try one from another Amiga or buy one to test.
They're not very expensive and seem to act as surge suppressors whenever
electrical storms come around.

Problem is that the chips on the 1200 are all surface mount. Do you know what
the chip numbers are for the CIA's on the 1200? (ie. how do I tell which ones
they are on the motherboard without schematics.
thanx.
Walter.
The part number on the chip may show '8520', but I can check with tech support
if that doesn't find them.

Anotehr thought on the dead drive would be.. Whenthe disk is inserted check to
see if the motor on the drive spins.. If it does not spin for a second then it
could also be the Gary Chip..
I had/have this problem.. I replaced both GARY chips only to find that that
did not help.. After some work with a logic probe I found that my Gary Chip is
not working on a couple pins… I found a work around for it and have not had a
problem with it.. Although I need to replace the Gary Chip eventually..
