Chances are, actually, that it *is* broken. The OS is very fault tolerant of errors in the directory. You'll think it's working perfectly, and then POOF one day your computer won't boot at all. OK, so that's in the more extreme category of cases, but it happens regularly, due to crashes, bugs, power loss, bad RAM, etc. etc. etc. Even if it never gets that bad, you can get things like overlapped files, or files that don't behave properly. DiskWarrior is a good thing to run every few months, as neither the OS nor Disk Utility will catch many of these errors. In my job for an Apple Authorized Service Provider, I'd say I run DiskWarrior on somewhere around half of the computers that come through to try and get them working again, or to try to prevent future problems, or to correct problems caused by bad hardware once the hardware has been replaced. Norton, on the other hand, is worthless (unless you have the one time in a thousand where DiskWarrior can't fix a couple problems).
