I have a customer who called me today and said she has a PowerBook G4 and she had an incident today, which has happened several times before, where she boots the machine, and it gets to the grey screen with the spinning circle, and never gets past that. She said one time she let it stay like that for over an hour. She also said that she started hitting keys and the something about the F12 key made it boot. I'm sure it was just a coincidence that she hit F12 right when it was going to boot, but does anyone have any ideas what causes OS X to hang like that before it even gets to the blue screen? As far as I know the grey circle kept spinning, so it wasn't a true freeze. I plan on running my HD utils and seeing if anything it up but I was wondering what people thought about it.

I had a similar problem with my other HD (60g IBM). I ran Diskwarrior (OSX) -and it has fixed the hang on start-up. I can't be more specific than that. It was also intermitten Good luck.

A friend just had that problem with his iBook. Unfortunately, DW didn't end up fixing it, just delaying the inevitable. He's had to send it back to Apple, but the genius at the local Apple Store didn't really know what was wrong with it...but he suspected the logic board was going bad.

I think that happens when it's checking the root volume during startup, before it's been mounted.
It would happen if the filesystem was not clean, usually because the system was not shut down in an orderly way (i.e. crash, or press/hold the power button, etc).
How long this takes will depend on the size of the filesystem, how many files/directories there are, etc. I think you can enable verbose booting to see the fsck going on.
If it wasn't because of an unorderly shutdown, the filesystem may have other kinds of errors that fsck can't fix?
Panther should address this with it's Journaled Filesystems.
