windows 7 - DVD drive disappears if I insert a disc, but will read the same disc if it was there at boot

I have a very odd problem.

If I insert a disc in my dvd burner that is blank, I can burn it.

If I insert a disc that has info on it, while Windows 7 64 bit, ultimate is on, it will disconnect the drive.

If I leave the disc in, and reboot, it will be able to read that same disc until I eject and reinsert, at which point, it does back to issue 2.

What can I do to fix this?
