[comp.sys.next] Drive won't allow insertion of optical disk

A friend of mine has an optical drive that will not accept any disk.
When the machine is powered on, it will ask for a disk, but it feels just
like it does before it asks for one; it physically resists insertion.
We tried booting his machine off mine over ethernet, and then choosing
mount from the 1.0a workspace manager menu, but this did not help.  I just
asked for the disk again, but the drive would not accept it.  I believe that
the last disk he had used in his machine before this happened was a double
sided Canon MO-502M, but we don't know if this had anything to do with it.

His machine is no longer under warranty, so we thought we'd ask if anyone
has had a similar problem and found a fix.  He said he remembered a posting
from a ways back describing a similar problem, but it was apparently not in the
comp.sys.next archives anymore.  Anyone know about the sensor that detects
insertion or anything?
