Notes on use
The floppy disk is an important data storage media with delicate structure and requires care. Keep the following notes in
mind to use it:
Insert the floppy disk into the floppy disk drive gently as far as it goes.
Attach the label to the correct position.
Do not write anything directly onto the disk surface with a pencil or ball-point pen.
Do not open the shutter.
Do not use the floppy disk in a dusty place.
Do not place anything on the floppy disk.
Do not leave the floppy disk in a high-temperature place (e.g., place exposed to direct sunlight or close to a
heater).
Do not leave the floppy disk with foods and drinks, or in a place exposed to cigarette smoke.
Do not leave the floppy disk near any form of liquid or a chemical or in a place where a chemical may be
accidentally sprayed over them.
Do not place any magnetic objects (e.g., magnet) near the floppy disk.
Do not clip the floppy disk or drop it.
Keep the floppy disk in a floppy disk case that protects it from magnetism and dust.
Write-protection
A floppy disk has a write-protect switch that prevents the stored data from accidental erasure.
You can read data from a write-protected floppy disk, but you cannot save data into the floppy disk or format
it. We recommend that you should write-protect any floppy disk containing valuable data unless you are about
to save data.
To write-protect a 3.5-inch floppy disk, use the write-protect switch provided on its back.
Disk format
To write data into a floppy disk, the floppy disk must be "formatted." "Formatting" is to initialise the floppy
disk and make it available for the system environment (operating system).
IMPORTANT:
Formatting a used floppy disk clears all the data contained in it, if any.
Formatting a floppy disk from the DOS command line is not available with the server.
Use a formatted floppy disk to work with it on the DOS command line.
The format method depends on your operating system. Refer to the manual that comes with your operating
system for details.
