I will check for that, but it was working minutes before I bumped the
power strip and it stopped working immediately after (it was the boot

other TM-100 when it's strapped as :0/DS0.
So that's where I'm at - the drive was
working before the power was
jiggled and now it's not and it doesn't appear to be the
electronics.
Make sure that the head is making good physical contact with the medium.
Sometimes the head suspension can get damaged and lose contact. Use an ohmmeter to check for continuity in the head
windings.
Yes. That was my plan. I have a dead 1541 because the read head is
open, so I've seen it before.
I accidentally ran a drive test with the head unplugged - same results
as when plugged in, so I'm really leaning towards a toasted head,
sadly.
Checking current auction prices on TM-100-2 drives... wow... they sure
got pricey. They are a long way from "how many do you want? Take
two, they're small" days. I think I have a bare drive on the
bookshelf out at my farm. Have to go look for that now.
Thanks,
