OK, so I went to put a regular DVD into my PB's SuperDrive, and it was met with resistance. I know for a fact that nothing is in there, as A) nothing is recognized and B) the regular keyboard eject button and various other eject commands yield zilch. I've restarted numerous times (wishful thinking, but you never know), and again, no dice. The only conclusion I can reach at this very early stage is that the SuperDrive has somehow been knocked out of alignment, though I have no idea how it could've happened. Thoughts? Things for me to try? I'm really stumped here.
