The drive tray on my Laseractive is stuck and I'm kind of freaking out. Anyone have any advice on fixing it?

Background: I accidentally shut the power off to the LA while it was in the savegame management menu on the NEC PAC. When I restored power, it correctly closed the tray. However, it now makes a faint whirring sound when trying to access the disc and will not eject the tray anymore. There is a disc stuck in there and it doesn't seem to recognize it. I tried removing the NEC PAC and accessing the drive using the physical buttons from the PAC-less interface, with no luck.
