Optical drive problems
NOTE: High-speed optical drive vibration is normal and may cause noise, which does not indicate a defect in the
drive, CD, or DVD.
NOTE: Because of different regions worldwide and different disc formats, not all DVD titles work in all DVD drives.
Problems writing to an optical drive
CLOSE OTHER PROGRAMS — The CD/DVD-RW drive must receive a steady stream of data when writing. If the
stream is interrupted, an error occurs. Try closing all programs before you write to the CD/DVD-RW.

URN OFF STANDBY MODE IN WINDOWS BEFORE WRITING TO A CD/DVD-RW DISK — See "Standby and Sleep
Mode" on page 31 or search for the keyword standby in the Windows Help and Support Center for information on
power management modes.

HANGE THE WRITE SPEED TO A SLOWER RATE — See the help files for your CD or DVD creation software.
If you cannot eject the optical drive tray

Straighten a paper clip and insert one end into the eject hole at the front of the drive; push firmly until
the tray is partially ejected.

Gently pull out the tray until it stops.
If you hear an unfamiliar scraping or grinding sound
