Disc dosent spin
I just solved this problem, very simple actually. Possibly can happen when the drive WILL close, but then loud noise as it tries to spin the disc up. Open the drive up (4 little screws on the bottom) and lift the lid up. If you look on the top white magnet spinner, the bottom side of the magnet system broke off of the disc motor. It will look like a little metal ring stuck to the white spinner thing whatever it's called. I popped that off and examined it, then used some krazy glue to stick it back on the motor spindle and it's away and going now. The reason the drive will not close, is because when the little magnet first breaks off it can get misaligned then when it tries to shut it gets in the way. The MAY be the cause to the problem. I fixed this issue today with mine, hitachi drive.
