I'll try to explain this best I can, here goes: My computer accesses my cd and my dvd drives normally....untill I pull the disc out and put in another one. At that point, it just reads unable to access "incorrect function". If I leave the cd in the drive, I can gaming for hours, or if I put in a dvd, I can watch a whole movie, pausing and even quitting and coming back, but if i pull the disc out, I am screwed until I reboot the pc, and then everything is normal again.....until I swap a disc out. I don't even have to put another disc in, the drive becomes inaccessable as soon I take out the disc. After searching the net and knowledge base forever, I have not come up with anything that works. Most things I found led to an issue with Roxio's software for easy cd creator, which I don't have installed at all. As long I reboot, it works fine, but only until I take the disc out. I am pulling my hair out trying to figure this one out, and hope someone out there can give a direction to in. Thanks if you are able to help.
