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. 24 PC 300PL User Guide
