Yesterday I woke to a completely dead Mac Pro 
Stuck on Grey screen, with Apple and spinning timer...
I tried everything, but eventually found in Verbose startup mode that files were missing on my startup disk. I am running the startup in Raid0, so I called up AppleCare. They were very helpful and tried to restore the individual files by going into root startup mode, but all to no avail.
Hence I eventually recreated the Raid0, and restored from Time Capsule -always have a backup
Now all is up and running again, actually the reformatting (w. zeroes) of the two 750GB HDs took longer than the restore, and it looks OK. The only thing I have lost (and my backup onto my NAS is a few weeks old) is my MS Main Identity, which I have excluded in the TC settings.
A few other things are a bit funny though:
1) When restoring, I did not get a destination disk immediately. After having recreated the Raid0, and having set it up for installation, I had to reboot to have the TC restore program acknowledge it as a viable destination drive.
2) All caches and indexes have to be recreated; Spotlight, Mails, etc.
3) My Downloads folder was gone - don't know why, so I recreated it manually.
4) And this is the worst one of these smaller issues; I use Entourage, and the first time I ran MobileMe Sync, it gives me a "MobileMe Sync Alert", and to "Merge all data". This only pertains to Calendar, which is bad because I have hundreds of items which is now out-of-sync!
Finally, and I do not know if this is a TC Restore issue; I have found that there are three named users of my main HD (the one restored) - "system", "wheel", and "everyone". This is not what I have on my other HDs. Who is "wheel"???
