Because of these incompatibilities, always indicate the diskette
type and density when you label your diskettes. (Usually this
information appears on the manufacturer’s label.)
If you have any combination of the above drives (1.2MB,
360KB, 1.44MB, or 720KB), you can copy files from one drive
to another-using the COPY or XCOPY command-as long as
the
correct diskette type is in each drive. You can also use these
commands to copy files between a hard disk and any type of
diskette. However, you cannot use the DISKCOPY command to
copy from one diskette drive to another if the two drives are not
the same type. For more about MS-DOS commands, see your
MS-DOS Reference Manual.
