most 5.25 & i believe all 3.5" drives of late (say 1988 or later) have a 
disk-change signal, though it is somewhat awkward. When a disk is changed, 
the next operation (read or write) will return an Error 06: diskette
removed or changed. most disk i/o routines are programmed to simply repeat
the command but a floppy write-delay cache could use to inform the user
that the cache must be flushed or something
