Summary: Looks like I was wrong


     It seems I was wrong about the disk level CRC.  Someone on
the net has wrote to me and confirmed that floppies do have CRC
built in on the controller level.  All I can say is, I've had
corrupted files load and execute under Radio Shack DOS and not
on OS-9.  The program in question was VIP Writer.  Keep in mind
that over the period of a year I booted VIP Writer often during
a day's work (maybe about 5-10 times per day), and it only happened
a couple of times.  That's not a bad average, but it did happen.
The program loaded and executed, shot garbage all over the screen
and went dead.

                                       Cheers! -- Jim O.
