There are so so many bugs in OS X and it's up to the users to ferret them out. Many years ago when I upgraded from 10.4 to 10.5, my external Firewire drive suddenly wouldn't even appear as a device, Apple was of no help. Turned out that the Oxford Firewire chip inside of the drive (OX911, an ominous chip name) needed an update and thankfully there was a Java based updater that did the trick. I never would have found that out without the Apple Support Community.

Hope somebody clones the site but I see it's protected by anti-crawler software now, thanks scrapers.
