[. . . ] The following steps will assist you to get your drive to work as a CD-ROM: If you cannot find CD-ReWriter in Explorer, restart your computer, or shut it down and then turn it on again. To check if the CD-ReWriter receives power properly, you can check the power indicator or test it by pressing eject button to see if the tray opens and closes. You can easily see which icon is CD-ReWriter by double-clicking "My Computer" icon, then right-click CD drive's icon, and selecting Eject. There are several ways to solve this problem as follows: The CD disc in the tray may be loaded upside-down, or a little off-center. After loading a CD disc, it will take a moment to let the CD-ReWriter read the disc information. When the indicator on the front panel stops flashing and stays green, it is ready for access.

If the disc you just loaded is a blank CD disc, try it later after copying some information to the CD. Q: What are possible causes of buffer underrun Hard Disk Extremely fragmented hard drive. We do not recommend writing from a compressed hard disk or disk partition. "Dumb" thermal re-calibration (only on very old hard drives). User's Manual E-10 Other Hardware Spin-down of CD-ROM drives you're copying data or audio from. Setting hard drive's read ahead optimization to "none" may cure buffer underruns in some cases. (Go to the Start menu | Settings | Control Panel | System | Performance | Advanced Settings/File System | Hard Disk and set "Read-ahead optimization" to "None. ") Networks Recording across the network (a network may be too slow to maintain adequate throughput speed). You can try the following procedures to prevent buffer underrun: Use a faster hard drive and defragment your hard drive at least once a week. If your source hard disk is more than five years old, make sure it does smart thermal re-calibration. It may be necessary to write audio at slower speeds than those you can achieve for data, since writing CD-DA audio requires streaming more bits per second to the recorder. Record in lower speed ­ it takes linger time to empty the buffer when recording at lower speed. Keep the CDs, the recorder, and your source CD-ROM drive free of dust. PC power management makes PC slower and thus it may result in buffer underrun. [. . . ] Please have the following information ready before you call or email us.
