Xbox 360 Disk Drive Failure

[Freeforall]

Hey, I have yet another problem. I dusted off my old 360, plugged it in and it works okay. But the disk drive will NOT open, and it doesn't hardly read disks at all. I have a perfectly new copy of PGR4 right here, right out of the box, and it simply won't read it. But now the disk tray simply won't open. I took off the front case and pushed the emergency eject button and it still won't work. Any ideas?
