 This means the CRC only checks the integrity upon loading?

 I suppose it could be just a glitch as you suggested. It's very rare that 
my OS=9 ever fails to work properly, unless it's a hardware problem. Then 
it's time to clean up connections and re-seat chips and the like. However, 
this time was different and I thought I would check in on it.
 It's fine now after the re-boot. Fortunately, not only do I backup the 
files with a .bu extension, but I regularly backup the floppy onto my other 
coco with a hard disk and also onto other floppies.
 You never can be too careful.

 If it were only so simple on the XP box.
