Optical drive problems
NOTE: High-speed optical drive vibration is normal and may cause noise, which
does not indicate a defect in the drive or the media.
NOTE: Because of different regions worldwide and different disc formats, not all
DVD titles work in all DVD drives.
Problems writing to a CD-RW or DVD+/-RW drive
CLOSE OTHER PROGRAMS — CD-RW and DVD+/-RW drives 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 drive.
TURN OFF SLEEP STATE IN WINDOWS BEFORE WRITING TO A CD/DVD — See
"Using the Sleep Power State" on page 53 for information on Sleep state.
CHANGE THE WRITE SPEED TO A SLOWER RATE — See the help files for your CD
or DVD creation software.
The drive makes an unfamiliar scraping or grinding sound
• Ensure that the sound is not caused by the program that is running.
• Ensure that the disc is inserted properly.
Hard drive problems
ALLOW THE COMPUTER TO COOL BEFORE TURNING IT ON — A hot hard drive may
