My computer's DVD burner drives have a weird problem. When i put in a disc, it doesn't recognize the disc is actually there. If you go into the drive, the files are all there, it's just the computer has no idea that the disc is in the drive (until you turn it off). This has caused every installation over 1 DVD/CD in size to fail because of it not recognizing the next disc required for the installation:(. I have scoured helpsites across the internet to no avail. Please help!
