❑ Make sure an adhesive label was not attached to the CD or DVD. Adhesive labels can come off while the disc is in the optical
disc drive and damage the drive or cause it to malfunction.
❑ If a region code warning appears, the disc may be incompatible with the optical disc drive. Check the DVD package to make
sure the region code is compatible with the optical disc drive.
❑ If you notice condensation on the computer, do not use the computer for at least one hour. Condensation can cause the
computer to malfunction.
❑ Make sure your computer is running on AC power supply and try the disc again.
What should I do if I cannot write to CD?
❑ Do not launch any software application or allow any to launch automatically, not even a screen saver.
❑ Do not use the keyboard.

❑ Are you using the correct DVD recordable media?
❑ Check which DVD recordable format is compatible with your computer's built-in DVD recorder (DVD-R / DVD-RW / DVD+R /
DVD+RW). Note the possibility that some brands of DVD recordable media do not work.
❑ The preinstalled software on your computer does not support copying DVD movies. Macrovision or a similar video protection
technology prevents users from copying DVD movies. Copying a DVD movie would be a copyright infringement and therefore
illegal.
