I'm having strange issues with my optical drives (two of them). When I first power up the computer they work like normal. I can read a cd or burn one, whatever. But after that first cd has been put in and I try to insert a another one (doesn't matter which drive) either of the drives wont open manually. Also, when I open the drive via paper clip hole and insert a different cd it still shows that the previous disc is still in there. Finally, after that lovely sturggle I reboot and it will read the new cd but only that cd and I'm back to square one...hope this makes sense.
