If you are copying from one floppy to another and they are both the
same type (double density, high density, etc.), the DOS command
DISKCOMP x: y: will compare the contents of two floppies, where you
would substitute the actual drive letters for x and y.  You could
compare the original floppy to the copy and verify the copy that way.
