Lenovo GP20N manual Troubleshooting

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.

2.You might have a damaged CD-R, CD-RW, DVD-R, DVD-RAM, or DVD-RW medium. Try a new medium or another brand of CD or DVD medium.

3.If you can read from a CD-RW, DVD-RAM, or DVD-RW medium in the writing drive, but not in another Multi-Read drive, make sure that a correct CD/DVD reader program is installed in the computer.

4.Avoid writing at the slower 1X speed unless required by your computer.

5.Make sure both the USB data cable and the USB power cable are connected.
