I have a pair of drives that had died back in '93 - first one drive stopped working and then the other not long after and that was the last time my //e saw any use. I was at my parents' house this weekend and pulled the whole system out of the closet in hopes of trying to resurrect it. When I attach either drive and power on the system, the drive spins but the drive head does not move to the outside position (and does not make the familiar clacking noise). I can move the drive head when the drive doesn't have power. When the drive has power, I cannot move the drive head.
Any thoughts on where to start to try to fix this? I've done some Googling but am having a hard time finding someone with a similar issue.
