I have a MacBook (early 2009 model), and yesterday the SuperDrive stopped working.
On attempting to push a DVD into it, it is physically stiff and doesn't want to go in, with a lot of pushing it goes further, and the automatic mechanism tries to suck it in (or at least makes a noise), but nothing happens. On closer examination, it would appear that something is catching the disks around the middle of the entrance of the SuperDrive which is preventing them from simply gliding in as they used to. I'm unsure whether its something broken, or perhaps a locking mechanism that has somehow got stuck. I did think that something might be stuck in there, but I am not missing any DVDs and I have tried restarting holding down the mouse button to eject, and while it makes the eject noise (which sounds healthy), nothing comes out.
I have tried all the obvious things – resetting the PRAM and SMC, to no avail.
I don't imagine that anyone has a fix for this as its probably a physical problem, but I thought I'd try as I am not currently near an Apple shop and I don't particularly want to be without my computer for too long, so I'd rather attempt to find a fix myself before doing anything else.

I just had this problem with my 17" mbp early 2009. ODD was blocked like there was disc already in, but of course there wasn't. Tried many times SMC & PRAM reset and Force shutdown. Sometimes the drive clicked and I managed to insert one disc, which was read just fine. But after ejecting it, the block was again there.
Then googled some more and typed "drutil eject internal" few times in terminal and all was OK again.
