Three of the four failing drives were official DEC

indicated by a sticker on the top. Interestingly, when Iooked at R7 on
the PCB, two of them had the resistor present but one end had been cut.
They've probably been cut in order to use the drives on a PC.
I soldered it back together but both drives still
fail. At least one of
the drives spins up but then back down again.
That can happen if the heads are stuck against the end stop inside the
drive. There's a rubber bumper that goes sticky. Alison posted more
information about that just a few days ago.
