    Click Save when done.

Step 3: Check discs
Common causes for CD/DVD failures are damaged or poorly manufactured discs. Plastic discs can be easily scratched and data on the disc can be destroyed if left in the sun. Discs damaged by sun must be replaced. If a disc is scratched, try to clean or repair the disc. Most home electronic stores offer disc repair kits at minimal cost.
CAUTION: When using disc repair kits, allow extra drying time above that required by the manufacturer. If the liquid from the repair kit has not dried thoroughly, the liquid may come off of the disc when the disc spins up. This can damage the optics inside the drive and make matters much worse.
Use the following steps to help determine if discs or the drive need further attention:

Samsung using cheap plastic says Gionee!!
