Chapter 4. Troubleshooting - Lenovo USB Portable DVD Burner User Manual

Chapter 4. Troubleshooting

Computer problems can be caused by hardware, software, or user errors. The information in this chapter
will help you solve problems or gather helpful information you can pass on to a service technician. You
might also need to refer to your computer or operating-system publications.
Review this list for any problem descriptions that might fit your situation:
The Lenovo USB Portable DVD Burner is not recognized by the operating system.
Ensure that the USB Y cable (including two USB A connectors) goes from the computer to the USB 2.0
Mini B receptacle connector of the drive. See "Connecting the drive" on page 5.
You cannot create a multi-session medium.
Be sure that there is enough space left on the medium for another session. Writing a session requires
lead-in and lead-out space (about 15 MB) in addition to the data that is recorded.
You cannot successfully write to a DVD-R, DVD+R, DVD+RW, or DVD-RW medium.
To solve the problem, do the following:
1. Make sure that the USB Y cable is correctly connected to the drive.
2. Verify that the process is not being interrupted by a screen saver, an antivirus program, an Internet or
e-mail program, or other software. Disable the functions that might interrupt the write operation.
Note: Replace the medium if it is damaged or scratched.
3. Verify that the hard disk has been defragmented.
4. Consult the hard disk drive manufacturer or vendor if an older hard disk drive is conducting a
thermal recalibration during a write operation.
5. Disable the Windows Auto insert notification function for your optical CD/DVD drives.
6. Remove the UDF Reader if it is incorrectly installed on your computer.
You cannot eject a CD or DVD medium.
To solve the problem, ensure that the drive is not in the process of writing to a medium, and then do the
following:
1. Right-click on the drive in My Computer.
2. Select Eject to eject the medium.
3. Turn off the computer. Wait 45 seconds; then turn on the computer and press the Eject button again.
4. If the above actions do not work, use the emergency eject. See "Manually ejecting media" on page 6.
You cannot read from the CD or DVD medium after successfully writing to it.
To solve the problem, do the following:
1. If you can view the CD or DVD medium in another CD or DVD player or you can see previous
sessions, the directory information might be damaged on the volume, making it unreadable. To get
ideas for troubleshooting, check the documentation that comes with the software.
2. You might have a damaged CD-R, CD-RW, DVD+R, DVD-R, DVD-RAM, DVD+RW or DVD-RW
medium. Try a new medium or another brand of CD or DVD medium.
