❖Back up your files to storage media on a regular basis.
Label the backup copies clearly and store them in a safe
place.
If your hard disk suddenly fails, you may lose all the data
on it unless you have a separate backup copy.
❖Use Error-Checking and Disk Defragmenter regularly to
conserve disk space and help your computer perform at
its optimal level. Consult your Windows® XP operating
system documentation for more information on these and
other utilities.
❖Scan all new files for viruses.
This precaution is especially important for files you receive
via diskette, email, or download from the Internet. Take
frequent breaks to avoid repetitive-motion injuries and
eyestrain.
❖Do not turn off the computer if a drive indicator light
indicates a drive is active.
Turning off the computer while it is reading from or writing to
a disk may damage the disk, the drive, or both.
❖Before turning off the computer, use the Turn off
computer command or Standby command. See
“Powering down the computer” on page 101 to learn
more about Standby.
The operating system records information, such as your
desktop setup, during its shut down procedure. If you do not
let the operating system shut down normally, details such as
new icon positions may be lost.
