To remove the write protection, move the switch up toward the
center of the diskette so the hole is covered.
Using the Hard Disk Drive
Unlike a diskette, a hard disk is rigid and fixed in place. It is sealed
in a protective environment free of dust and dirt, so you cannot see
it. A hard disk stores data the same way as a diskette, but it works
much faster and has a much larger storage capacity.
You can do almost all your work on the hard disk and copy your
files to diskettes whenever you need to make backups or transfer
data to another computer system. However, to ensure that you
always have plenty of space available, keep only files you use
regularly on the hard disk. Store your other files on diskettes.
Note
You must prepare a new hard disk before using it for the first
time. Make sure you have completed all the procedures in
Chapter 3 to prepare it.
Caring for the Hard Disk
To avoid damaging your hard disk, take these precautions:
Keep your computer away from magnetic fields, such as
electrical appliances, telephones, and loudspeakers.
Keep your computer in a moderate environment. Hard disks
work best at room temperature and in normal humidity.
Never turn off the computer’s power or the HDD POWER
switch when the HDD LED is on. This light indicates that the
computer is currently copying data to or from the hard disk. If
you interrupt this process, you may lose data.
Never attempt to open the hard disk unit. The disk itself is
enclosed in an airtight container to protect it from dust.
