Jammed HD from Mac IIci
Posted by: Flamingtoasters on 2007-08-10 21:37:55
Hi

I recently pulled my Mac IIci from storage and tried to boot it up. The internal HD didn't start (it is a quantum). Is there any way I can fix the HD, or should I just pitch it?

try taking the drive out of the iici and shaking it, kinda hit it then try it again

The old 40MB drive in my IIcx occasionally does the same thing. I find that giving the side of the case a firm slap will normally get it going! However I've just replaced it with an 80MB Quantum drive from an LCII as the old one was causing a few problems.

I tried everything you said. Now the LED starts flashing every few seconds. I think this means it is dead. My next idea is to leave it on for around 20 minutes and then try it again.

If it is an original drive it may be suffering 'stiction': intermittent loss of rotation from failed/failing bearing lubrication. The next phase will be screaming (these swans do not sing sweetly before they cash in their chips, to mix metaphors a little), or chilling silence. Count on needing a replacement, soon. If you can induce it to spin continuously just once, get any data that you value off the drive, and then inter it.

Maybe stating the obvious a little, but have you checked that the drive power supply cable is connected properly?

1. The HD is plugged in properly and getting power.

2. How would i get it to become un-jammed so it can spin?

How to be a (rotational) jerk: Disconnect power and data cable then remove the disk assembly from the IIci. Remove the disk from the spring tray. The disk rotational axis is two inches back from the face of the SCSI connector edge, and centered with respect to the faces of the long edges, and the internal platters holding the data are about 3.75 inches in diameter. The idea is to hold the disk case by the long sides with fingers and thumb opposite, with center of your lower arm in line with the rotational axis of the disk inside so that when you torque the case by rotating your wrist, the case spins rapidly as possible, while the disk inside with its inertia tends to lag the case rotational snapping motion and hopefully breaks free. So place your thumb about 2 inches back from the SCSI end along a long edge, fingers on the long opposite side, arm down and disk parallel to the floor, twist as quickly and hard as you can (without spraining your wrist/elbow) both ways several times then see if it will spin up. For this little experiment it does not matter if the PC board faces up or down, just do not drop the drive. Probably a little elbow bend will be easier on your arm. Good luck being a jerk. [😀] ]'>
