Yesterday I went to check the contents of an unmarked CD+RW and it went in fine, checked it and I ejected it. Shortly after I ejected it, the CD drive made a sound like it failed and is ejecting it again! So at that point I was like huh, weird. But it proceeded to keep humming, making some noises, etc... In a certain pattern repeatedly at 5-6 min. intervals. I thought maybe its just confused, so I tried to put the CD back in but its closed! The only time I managed to get it in was when it made noise and opened, when it did go in it took it and read it then spit it back out fine. But it still makes noises constantly. So I turned the computer off to get some sleep, and either Time Machine or by some work of magic it turned itself back on and woke me up with the CD drive noises. It sounds crazy, but is this any sort of a known issue, and is there a way to resolve it / disable to the CD drive (short of unplugging it)? Thanks!
