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 drive - the machine failed to reboot after the momentary power loss and the diskette was not damaged - the same diskette boots in the other TM-100 when it's strapped as :0/DS0. > 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, -ethan
