31/2-inch drive/diskette compatibility
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 (1.44 MB,
1.2MB, 720KB, or 360KB), 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 Reference Manual.
Caring for Diskettes and Diskette Drives
Follow these basic precautions to protect your diskettes and
avoid losing data:
If you have a diskette that contains data you don’t want to
accidentally write over or erase, be sure you write-protect it.
This is especially important for your operating system and
application program diskettes. See “Write-protecting
Diskettes,” below, for more details.
Do not remove a diskette from the diskette drive or reset 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.
