Well, my SCSI PlexWriter 12/10/32 (firmware 1.05) has never given me
THAT problem.  There is one funny thing that is DOES do, though.  On a
small number of my audio discs (mostly burned ones but a few commercial)
it will spend about 10 seconds trying to read the TOC (I guess that's
what's going on anyway), then it will spin down and a light will blink.
At this point all attempts to access the media result in a "no disc in
drive" type error.  This is with discs that are unscratched and read
fine on other drives.

Other than that it never gives me any problems. <shrug>
