iTunes did this to me one night. That program has a mind of it's own I swear. I'm not playing the "PC Rulz, Mac Sux" card, but I must say that this program is ****e. One night I had it open but minimized and I was doing other things in Sound Forge. Suddenly my system would freeze up, and both my drives would eject at once. I press the eject button again, and they stay retracted for a minute, then spit back out again. I killed iTunes, and I closed the drives again. That time they stayed shut. So I go to open iTunes again, and the damn drives ejected again on program startup. I silently smacked my power button and waited patiently for the system to shut down... I only use it now to change the playlist on the shuffle, to hell with using it to convert to AAC.
