Bob, There is a mechanism in your floppy drive which detects "change of media"; i.e., it signals when a floppy has been removed/inserted. DOS uses this info; it stores your floppy's "directory" info in memory and uses _that_ instead of reading your floppy each time. When the floppy is changed out for another, DOS detects it and then reads the disk itself and stores its info. Now, if the "change of media" signal from the drive is broke, it may think that there's "always" a floppy inserted and never changed out! This happened to me recently. You can either: 1) try to fix the drive; or 2) buy another drive for $70 or less. I did the latter, because I'm a klutz at repairs :-). > Thanks! Your welcome!
