Do you have any idea why your system crashed?
To just reinstall the OS because of a crash without trying to find the reason for the crash is counterproductive. Generally crashes indicate hardware problems and reinstalling the OS does absolutely nothing to fix any hardware problems.

I believe it is to do with a dodgy Seagate FW drive that has been messing with the SMC and causing general instability since I upgraded to Snow Leopard a while back. The Seagate drive (freeagent something or other) has firmware issues with how it spins down and is generally a bit cranky when other firewire devices are plugged in. It regularly unmounted itself and other drives and caused me to reset the firewire bus , PRAM and SMC on a few occasions. Last night, the Mac wouldn't boot past the blue screen and I was forced to do a re-install of Snow. This was the final straw and the Seagate drive has been kicked around the room a few times on it's way to the bin.
Anyway, after eventually getting the hardware to reset and thoroughly checking my boot volume, all seemed OK after the reinstall. With the exception of the strange ignore ownership box refusing to stay ticked...
I've since managed to fix it by doing: sudo rm /var/db/volinfo.database thanks to some more Googling.
I can only presume that what ever the Seagate did corrupted the volumeinfo file for all volumes (including the boot volume) and this is why I couldn't boot last night.
So, long story short - it seems fixed for the moment, but I'm furiously duplicating and triplicating all of my backups as I am only 90% sure that the problem is solved....
Thanks
