I am currently having a problem with my CDRW drive. It is a Philips CDD4801/81 CDRW. I am running Windows 2000 Professional. I started having this problem about a week ago, but I did not install any new hardware or software, and made no configuration changes. I started receiving error messages when trying to burn CD-R’s that stated that the CD-R disk had insufficient space. I tried about 4 different brands of CD-Rs and CD-RWs, each time receiving the same message. I then tried to read a CD-ROM disk and an audio disk in the drive, and received an error message stating “The disk in drive F: is not formatted. Do you wish to format?”. I figured it was a problem with the drivers, so I unistalled them and the drive, and then reinstalled them. That did not fix the problem, so I checked my IDE cables and power cables, and they are fine. I then bought a CD lens cleaner, and that did not fix the problem. I contacted the PC manufacturer, Gateway, and I received a new drive, but I am experiencingthe same problems. I checked the BIOS also, and everything looked fine. Please give me any ideas as to the cause of the problem and the resolution. I am at wits end because I have tried everything and to no avail. Thanks for your help and your time.
