I have a nice original NeXT machine, with an HP 660 97548sn HDD in it. This disk has some data that I wanted to rescue at some point, and between then and now, the disk had started acting up. The disk motor will spin, but once the NeXT boot process begins (or SCSI sense on a PC with a SCSI card), I hear a click, and the motor spins back down. My guess is that a head is stuck? If so... a) is there a way to resuscitate the disk, and b) is there someone that repairs older drives like this, and c) if not, can I do it myself. FWIW. The data on the disk is, I believe, one of a kind, rare, data, and the machine is overall in excellent condition.
