2-4 Maintenance
Maintenance
The CD-Writer Plus drive requires no maintenance or cleaning. If you
simply keep your CDs clean, you will prevent most problems.
CAUTION: Do NOT use the CD-ROM cleaning discs that rely on a small brush
to sweep dirt off the laser. Do NOT use high-pressure air to clean the inside of
the drive. These cleaning techniques will damage the CD-Writer Plus drive.
Identifying CD-Writer Plus’s Drive Letter
Not sure which drive letter was assigned to the CD-Writer Plus
drive?
The CD-Writer Plus drive will have a drive icon just like a CD-ROM drive
icon. You can determine which icon is your CD-ROM drive and which
icon is your CD-Writer Plus drive by double-clicking on the My
Computer icon, right-clicking on the CD drive icon, and selecting Eject.
The tray of the selected drive will open.
