This can happen when the "Detect Disk Change" sensor is not working on the
floppy. The index of a floppy is read into cache memory when a disk is
first accessed and subsequent accesses to the floppy use the cached
index. However, the cache is refreshed when the sensor detects the disk
has been changed. It sounds like the sensor never sends the signal for the
cache refresh to occur. Most floppy drives use a light sensor to detect
the change. Try re-booting the machine and see if the first floppy
accessed has it's contents kept as the floppy index no matter what floppy
is in the drive. That would confirm a bad sensor.
