    [verbage about DIR not sensing change of floppy disks]



    Yes, your symptom is familiar.  Someone [has|is] [used|using] an altered
[disk|os] on your AT, and your system now thinks that drive A: is a harddisk.
Watch out, this has cause data loss at a local college due to the directory
of the first disk being overwritten on the second.

    This symtom was first though to be a virus, but it was later detected
to be a students attempt to speed up floppy access by making the AT think 
it was reading a harddisk (the directories of a hardisk are cached to 
increase system response (that hard disk ain't going anywhere)).
