Because of possible incompatibilities, always indicate the
diskette type and density when you label your diskettes.
(Usually this information appears on the manufacturer’s label.)
Note
If you want to format a 720KB diskette in a 1.44MB drive or
format a 360KB diskette in a 1.2MB drive, make sure you
include the correct parameter in your format command.
See your operating system manuals for instructions.
If you have any combination of the above drives (1.44MB,
1.2MB, 720KB, or 360KB) and you are using MS-DOS, you can
copy files from one drive to another-using COPY or
XCOPY -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
MS-DOS DISKCOPY command to copy from one diskette drive
to another if the two drives are not the same type. For more
about copying files and diskettes, see your MS-DOS or other
operating system manuals.
