Chapter 4. Troubleshooting
This chapter provides troubleshooting hints and tips to assist you when you experience problems with your
drive. You might also need to refer to the publications that come with your computer.
If you encounter any of the following problems when using the drive, refer to the corresponding answers.
You cannot create a multi-session disc.
Make sure that there is enough space left on the disc for another session. Writing a session requires lead-in
and lead-out space (about 15 MB) in addition to the space to accommodate the data that is recorded.
You cannot read from the CD or DVD disc after successfully writing to it.
Do the following:
1. Try the CD or DVD disc with another CD or DVD player. If you can read the CD or DVD disc in another
CD or DVD player or you can see previous sessions, this indicates that the directory information might
be damaged. Check the documentation that comes with the CD or DVD player.
2. You might have a damaged CD-R, CD-RW, DVD-R, DVD-RAM, or DVD-RW disc. Try a new disc
or another brand of CD or DVD disc.
3. Avoid writing at a speed slower than 1x unless required by your computer.
The DVD playback cannot resume after your computer resumes from suspend mode.
This is normal with some device drivers. The DVD playback will continue after you exit and restart the
PowerDVD program.
DVD movies do not start automatically when you insert the disc into the drive.
You might have chosen to always start data discs in file only mode. Refer to the Microsoft
®
Windows
®
Help
and Support program.
A message is displayed, indicating that there is a copy protection error, and playback stops when
using the PowerDVD program.
Do one of the following:
• If an external monitor is connected, ensure that the external monitor is connected to a digital video output
connector on your computer, such as a High Definition Multimedia Interface (HDMI), DisplayPort, or
Digital Visual Interface (DVI) connector.
• Ensure that your graphics card and the Protected Media Path are working correctly when you are using
the drive on Windows operating systems.
