You cannot successfully write to a CD-R, CD-RW, DVD-R, DVD-RAM, or DVD-RW medium.

To solve the problem, do the following:

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

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 Notify function on your optical CD-ROM and CD-RW drives.

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.
