9. TROUBLE SHOOTING
(11) An Optical disc cannot be recognized or cannot be read.
<Possible cause>
An unsupported or bad Optical disc is used.
<Action>
1. See "5.1 Equipment Specification" and make sure that the Optical disc you want to use is
supported.
2. Check that there are no scratches or dirt on the Optical disc. If the disc is dirty, clean the
disc.
3. Select Start > Computer and check if the DVD drive is recognized.
-> If the DVD drive is not recognized, restart the equipment.
4. Use another Optical disc.
< NOTE >
If you use a USB DVD drive, depending on the DVD drive, it may take around 10
minutes to read an Optical disc at the startup of the equipment. If this situation
occurs, you may be able to resolve this problem by selecting Disabled for Legacy
USB Support on the Advanced tab in the BIOS settings.
(12) Writing to an Optical disc fails.
<Possible cause>
Possible causes are insufficient HDD capacity, an unsupported Optical disc, or a
compatibility issue. Writing to an optical disc is not supported because there might be a
compatibility issue between the DVD drive and the optical disc. Before using the writing
function, verify the Optical disc to be used.
<Action>
1. Check that the Optical disc is writable.
2. If enough free space is not available for the work area on an HDD, clean up files and
increase free space on the HDD.
3. Check that there are no scratches or dirt on the Optical disc. If the disc is dirty, clean the
disc.
4. Check whether another Optical disc is writable.
5. Replace the Optical disc with an Optical disc from another manufacturer.
6. When writing to an Optical disc, select "With a CD/DVD player" in the "Burn a disc" dialog
box on the OS, and then change the speed to a lower speed when writing.
