Hi all, I'll keep this brief and easy reading. I have a 2.2ghz santa rosa 15" MBP, and just decided to give it a quick spin with onyx (latest version i may add). After checking the startup disk it said there was an error that needed repairing. Surely enough after a disk check in disk utility, it said the same thing. So i dug out the Disks that came with my MBP and set about sorting the problem. First time i booted from the disk i pressed D accidently and so started up the hardware test. I thought why not now its booted up. Checked the extended test option and after an hour it said there was a problem with the hardware. all it gave me was this: 4SNS/1/40000000: Th1H Of course this worried me, not only are the problems stacking up, but i haven't a clue what the heck it is. So I restarted and pressed C this time on bootup, and used disk utility to repair the startup disk. Only this time it said that it was fine and didn't need repairing. odd i thought, So decided to do the extended hardware test again. And this time, it said that my mac was fine and in good shape! So now I'm back on the desktop, ran Onyx again and low and behold, its saying that everything is fine. What on earth is going on? If someone has any idea at what might be happening, then please comment. I really cannot afford for my only computer to suddenly break down.
