Because of these incompatibilities, you should indicate the
density and diskette type when you label your diskettes.
(Usually this information appears on the manufacturer’s label.)
If you have any combination of the above drives (360KB,
1.2MB, 720KB, or 1.44MB), 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 use these
commands to copy files between the hard disk and any type of
diskette. You cannot use the DISKCOPY to copy from one
drive to another if the two drives are not the same type.
Caring for Diskettes and Diskette Drives
Follow these basic precautions to protect your diskette and
avoid losing data:
Do not remove a diskette from the diskette drive or turn
off the computer while the drive light is on. This light
indicates that the computer is copying data to or from a
diskette. If you interrupt this process, you can destroy data.
Remove all diskettes before you turn off the computer.
Keep diskettes away from dust and dirt. Small particles of
dust or dirt can scratch the magnetic surface and destroy
data. Dust can also ruin the read/write heads in a diskette
drive.
Never wipe, brush, or try to clean diskettes in any way.
Keep diskettes in a moderate environment. They work best
at normal room temperature and in normal humidity. Do
not leave your diskettes sitting in the sun, or in extreme
cold or heat.
