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.
Turn off Standby mode in Windows before writing to a CD/DVD-RW disc — See Standby Mode or search for the keyword standby in the Windows Help and
Support Center for information on power management modes.
Change the write speed to a slower rate — See the help files for your CD or DVD creation software.
If you cannot eject the CD, CD-RW, DVD, or DVD+RW drive tray
1. Ensure that the computer is turned off.
2. 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.
3. Gently pull out the tray until it stops.
If you hear an unfamiliar scraping or grinding sound
l Ensure that the sound is not caused by the program that is running.
l Ensure that the disk or disc is inserted properly.
