Completely dismantled the platters from the spindle, put it back together, and got several more months of service out of it, until it wouldn't spin up on its own (had to kick-start it). >> Kyle, that's really neat. Would you tell more about how you got the platters out? Were you able to lift the heads off the platters before retracting them, or were you simply able to slide the heads across the platters, and off the platters? Thank you, John S.
