Sounds like it's reading from the cache and not the disk.
This happens if the software (DOS?) thinks that the floppy disk is
really a fixed disk and can't be changed. In DOS there is a command
FASTOPEN that means _never_ look at the physical media - maybe you
have something like this in an AUTOEXEC.BAT file?

Unix-like operating systems are even hairier, you have to explicitly
remount when you change the floppy.
