NeXT-FAQ.internal: Questions about NeXT internal hardware

*** Subject: I3. Why OD continually spins up and spins
down?

A big problem with the Cannon optical drives is that air
flows through the drive to cool it.  Dust accumulates
inside the drive causing it to fail with the continuous
spin-up spin-down syndrome.  NeXT as part of it's 040
upgrades provides a dust filter to prevent this.  If your
drive has this problem it usually can be fixed simply by
cleaning out dust from the drive.  NeXT sells a cleaning
kit for both the drives and the optical disks.
