I've got a pioneer DVD drive and a lite-on CDRW drive that have worked wonderfully for the past 2 years or so, until now. They have stopped recognizing CDs. If I put a CD into my DVD drive a window pops up saying it is not in a format windows can read if I click on the drive to view the contents; if it goes into the CDRW drive nothing happens at all when I click on it. Device Manager shows they are working properly with no conflicts, I have made no changes to the drivers or anything like that recently. The weirdest part is that if I leave a CD in one of the drives and restart the computer, it will show up as being in there and works perfectly when windows starts. But if I hit eject and put it back in it dissapears and has the problems as mentioned above. Please help, this is getting annoying.
