![]() We usually clean discs by spraying them lightly with window cleaning solution and gently drying them with a soft cloth. If this happens, it is often because the disc itself is dirty or scratched, so clean the disc or try a different disc before assuming the drive is at fault. The first symptom of a dirty optical drive is that you get read errors on a data CD or DVD or degraded sound or video from an audio CD or DVD-Video disc. If the firmware update doesn't solve the problem, try a different brand of disc, preferably one that is recommended by the maker of your optical burner.If not, call their tech support number and ask. Check the manufacturer's support site to see whether a firmware update is available for download. If an optical writer fails while burning the first disc of a new type of disc or a new batch of your usual type of disc, update the drive firmware.If a DVD drive refuses to read CDs but will read DVDs, or vice versa, the mostly likely cause is that one of the two read lasers has failed.If read errors occur with different discs, use a cleaning disc to clean the drive. ![]() If you experience read errors, try a different disc, or clean the current disc.Windows 2000 and Linux distributions that use a kernel earlier than 2.6.11 are particularly subject to this problem. Older ATA drivers sometimes become confused if SATA and PATA devices are used together. If you install an SATA hard drive in a system that was previously all PATA and the optical drive "disappears," make sure that the operating system is fully updated.If you've recently worked inside the system, the most likely cause of a complete drive failure is that you left the power or data cable disconnected or that you damaged the data cable. Gross failures, such as the computer BIOS not detecting a drive that formerly worked normally, are usually caused by an outright failure of the drive itself.When an optical drive behaves strangely, the first step is to reboot the system.Use the following guidelines to troubleshoot optical drive problems: If the drive has no emergency eject hole, the best option is to disassemble the drive carefully to retrieve the disc. Insert a paper clip into the hole and press firmly to release the drive tray. ![]() If the disc being held hostage is valuable, look for a small emergency eject hole in the front panel of the drive. If that doesn't solve the problem, the drive itself is probably defective. If that happens, power down the system completely, allow it to remain off for a minute or so, and then power it back up. Optical drives sometimes refuse to eject a disc, using either software eject or the eject button on the drive itself. Even these utilities aren't foolproof, because some high-quality disc manufacturers have sold master stamping dies to other companies, whose discs are identified as coming from the company that produced the stamping die rather than the company that actually produced the discs. The best way to determine disc types is to use DVD Identifier ( ) or CD-R Identifier (no web site search Google). In general, the best discs are made in Japan or Singapore and the worst in Taiwan and Hong Kong. It's also common for spindles of different capacity 25, 50, or 100 all with the same brand name, to contain discs made by different companies. It's quite possible to buy two apparently identical spindles of discs, sometimes with the same SKU, and find that one was made in Japan and the other in Taiwan, by different companies. Some companies put their own brands on discs from different manufacturers. Some companies manufacture discs that are rebranded by several other companies, and may or may not also be sold under the manufacturer's brand name. There is little relationship between the brand name of a disc and the company that made it. Assuming the drive is installed and configured properly initially, it should be problem-free throughout its service life. ![]() Optical drives generally work or they don't.
