Superdrive Persistent Eject Sound While Sleeping

    When sleeping, the Superdrive continously tries to eject a non-existent disc every few minutes. If there is a CD in the Superdrive, the computer stops trying to eject and works normally. As soon as I take the CD out and try to let the computer sleep, it keep waking up trying to eject the mystery CD.

    I have tried re-installing the OS. When I got the machine, I did import data and applications from another MacBook Pro. Could have this screwed up a setting?

    The drive actually works fine as I burnt a DVD the other day.

    Is this some sort of setting issue?

    Thank you for all your help.

    If you have an ExpressCard in the slot, try removing it. Also try unplugging every external device other than power. Also, try putting it to sleep with the lid open, to see if it wakes all the way back up, or is indeed just 'ejecting'.

    I had a similar odd symptom, 'ejecting' repeatedly while it was asleep, that I figured out the computer was waking all the way up, it was only if I had the lid closed, it would be waking up, going to sleep, waking up, going to sleep, over and over. The culprit was an ExpressCard memory card reader. As soon as I took the memory card reader out, it started going to sleep and staying asleep correctly.

    Also, applying the ExpressCard Update 1.0 patch fixed it; although obviously if you don't have an ExpressCard plugged in, that's probably not it for you.

    P.S. It worries me a little that Apple released an 'update' that is version 1.0... Does that mean that the MacBook Pros, as released, are using pre-1.0 software for their ExpressCard drivers?

    Are you sure it isn't just the normal noise of the drive checking itself (or whatever it's doing) whenever the thing wakes up? My MacBook's drive makes that odd little mechanical noise whenever the machine wakes up, so it could be something else causing the machine to wake up, and the drive noise is just how you know about it.

    Yes because it wakes up every few minutes from sleep even though I am not touching the machine and even though there is no vibration to make the laptop think it is being used.

    I was not using the ExpressCard slot but I installed the update anyway and I have not had the issue since! Thank you! I hope this was the issue.
