Thread: My CD drive won't open- Ubuntu

Yeah, so the other day I tried to burn a CD for a friend with Brasero, and it wouldn't play. (I think I made a thread about it)
Anyway, to day I download some updates, and one of them is for Brasero. The info says that it fixed a problem that didn't allow the CD's to play in a CD player.
At this point I'm thinking, Awesome!
Now I'm not. Awesome is the last thing I'm thinking.

I go to burn a CD, and Brasero seems to be stuck on the same step. It skipped straight to "burning tracks", whereas usually it says some other stuff first. So it's stuck on this step for about five minutes, so I cancel the process. Only it doesn't want to cancel. So I keep clicking cancel and it finally quits. Then an error pops up that says that Brasero stopped unexpectedly. Okay. Fine.

But now, my disc drive will not open. I hit the button on the tower and it just sits there. I try right clicking on the desktop icon telling me that I still have a disc in and click unmount, nothing happens. No error, it just sits there.

So I decide to try to use a different program to burn some music to it, and maybe it'll eject it.
Nope. Ubuntu tells me that the drive is busy. And it sounds like it's trying to read the disc.

What do I do?
