    I'm pretty sure it means the system can not find the boot drive, but...

    My iMac stays on 100% of the time, but a few months ago I turned it off for about 18 hours during a storm. When I turned it back on, I got the flashing question mark. I turned it off & back on about 8-10 times, when it finally booted up just fine.

    It never does it at a reboot, only if off a while. For several months, it did this any time it was off a while.

    About 6 weeks ago, it stopped doing it! Now, I can't MAKE it happen!

    I should feel lucky, but I'm also nervous about an impending failure. When SL came out, I repartitioned the drive, first going to MBR, then back to GUID, just to re-write everything. That neither helped (the issue was already gone), nor hurt.

    It still won't ever do it. Fluke, or should I be planning for a drive failure?

    Could be a drive failure or a corrupted boot sector, this happened to mine and it was a corrupted boot sector, I had to reinstall the OS in order to fix it. It sounds to me that that's all it was for you too. I would say you are OK as long as you don't start hearing some strange noises coming from your hard drive.

    Make sure you keep recent backups just in case. The last thing you need is to lose everything.
