This morning I ran the Repair Permissions command from inside the Disk Utility. Ever since then my MacBook wont move past the splash screen when booting.
I've revolted in verbose mode and I see that it is trying to repair the disk but then terminates with 'Unable to repair the volume'.
Since then I have tried running the Disk Repair from the Snow Leopard install DVD and it quits with the same error. Is there a way I can repair this thing without reformatting and installing over again?
How does something so simple as a permissions repair make the system unbootable like this?
