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.
Yes, I saw those messages. At this point I'm not up for opening up
the drive to attempt a fix though. I guess if one of my good ones
stops working I may change my mind. Instead, I'm starting to look
into what is necessary for a minimal RT-11 bootable RX50 diskette.
Unfortunately, that's the only medium I have for moving things to the
hard drive on the PDP-11.
