O.K. I'm having a similar problem to many other people here. My CD-ROM and CD-RW won't work about 95% of the time. They either both work, or both do not work(usually do not). They are recognized as working properly in the Device Manager every time though. Removing them will cause the computer to detect them at the next start-up, however they STILL do not work when I try to use them. I get the message E:/ drive is not accessible, the device not ready. Occasionally they do work, but it is very rare and completely random as far as I can tell. Also, I tried to set the read ahead option to off (no read ahead) but that didn't help me at all. I'm clueless and need help. Thanks.
