Write-protecting diskettes
It is possible to accidentally format a diskette or unintentionally write data
to it. Important information can be written over or lost. For this reason, it
is a good idea to write protect important diskettes. You can read data from
a write-protected diskette, but you cannot erase or change the data.
The write-protect switch is located on the back of a 3.5-inch diskette. The
write-protect switch can be used to prevent data from being written to or
erased from the diskette. If a 3.5-inch diskette does not have a write-protect
switch, it is permanently write-protected.
To allow writing to the diskette, slide the switch so the write-protect
window is covered.
To prevent writing to the diskette, slide the switch so the write-protect
window is open.
Using a CD-ROM drive
Some models have a preinstalled CD-ROM drive. CD-ROM drives can play
back or read from a CD but cannot write information to it. CD-ROM drives
use industry standard, 12 cm (4.75-inch) CDs.
Follow these guidelines when using a CD-ROM drive:
Do not place the drive where there is:
– High temperature
– High humidity
– Excessive dust
– Excessive vibration or sudden shock
– An inclined surface
– Direct sunlight
Do not insert any object other than a CD into the drive.
Before moving the computer, remove the CD from the drive.
