    mine doesn’t spin up at all. if I move the head it will park itself but the
    platter never spins

    H**l my friend, where can I obtain an SCSI hard drive reader like yours?

    i had a similar problem,it was a stopper where the head parks.
    i found this out by taking the drive apart after i replaced it.
    the rubber had virtually melted to a sticky goo.

    Wow, that’s really interesting! I have one of these drives, a 120 MB
    ProDrive ELS IDE unit from school. I never knew hard drive death-by-opening
    was caused from enamel wearing from the heads. I always figured it was from
    foreign material settling on the platters. Is this enamel wear due to the
    unestablished air bearing between the head and the platters when the drive
    is open? Would drives with GMR heads withstand this better? Great video!

    Those old Quantum drives were some real workhorses. There’s a plastic
    tongue on some of these that serves to lock the headstack in place.
    Sometimes it gets sticky and won’t release reliably. I was able to
    carefully defeat one of those. Stiction is definitely another big problem
    with the later Fireball series and the SCSI variants (not sure if they’re
    called Fireball or something else). I usually give them a sharp “kink” at
    power on and then I get all the data off to another drive!

    @uxwbill I have an old 1997 intel server, that had Quantum Vikings in
    there. 4.5GB SCSI drives, all 10 of them. 7 of them failed from stiction. I
    was able to take all of them apart and free the platters on all the drives
    from stiction, and there was goo left behind on the platter. almost like
    they overheated. Then i found a failed backplane fan. So there you go. I
    took a microfiber and cleaned all the goo from all platters. The drives
    fired up and worked reliably for years, still do.

    I finally found a permanent solution. I rebuilt a 40mb and an 80mb drive
    and they work perfectly fine. Had to remove the platter from the 80MB drive
    to do it. Multi platter drives need a special removal tool and I dont have
    that. So no go on that part. I got one more 80MB left I need to repair so
    ill do a video on that.

    My Macintosh Performa 410 had the same problem

    There is no permanent solution, Actually its the rubber crash/park stop for
    the head actuator that actually starts to degrade and gets sticky. When
    this happens the head cannot move from park.

    Thank you for the awesome video techknight! This trick worked perfectly for
    me to get the hard drive in my old LC 475 to work. It was a great feeling
    as soon as I heard the drive make its signature clicking noises after I
    unparked the head 🙂

    @themaritimeman It depends. not sure on the GMR head. Haven’t done enough
    research. Yes its caused by the much lower air bearing.
