Need some help repairing a friend's Macbook

Hey everyone,

I haven't really got much experience with Macs (yet, I'll be receiving my MBA next monday), but my friend asked me to try and repair his black Macbook. So I guess I need some of your help

Originally, it would freeze during boot up, during the spinning wheel screen. I turned on verbose and the last message was something about AppleYukon. I then booted up using single user mode, ran the file system check which found some problems and repaired them.

Next time I booted up, it went all the way to the blue screen with the mouse, and then it froze. I had to power off using the button, which must've screwed up the file system again, because it would stop at the AppleYukon message again.

I've burned the SL image to a 16GB USB stick, and booted into the installation manager. I ran Disk Utility's Verify Disc which gave me "Error: This disk needs to be repaired. Click Repair Disk.", which I did. Then it gave me "Error: Disk Utility can't repair this disk. Back up.... and restore your backed-up files."

I then ran Verify Disk again, and it finished fine with the message "The volume Mac HD appears to be OK." The Verify Disk Permissions and Repair Disk Permissions options are grayed out, though. The next time I restarted, I got stuck in the blue screen again...

If I have no further options, I'll just back up the disk's contents and reinstall SL, but I'd like to know if there's anything else I can do...

And when it comes to backing up the disk, is doing it through the terminal my only option?


Cheers

EDIT: I've now enabled journaling on the partition, so that power-off do not disturb the filesystem. I've stopped stalling at the ApplYukon message ever since. Still stuck at the blue screen, though...

 

Ok, so I backed everything up, reinstalled SL and applied all the updates. It's running pretty much flawlessly, so I don't think there's anything wrong with the hardware...

 

I'll run those tools to confirm, but since the HDD is only 3 years old (he replaced it, I don't know why), I have a hard time believing it's failing so soon. Anyway, I've installed SL on another HDD so that if the other one fails, he can have a running system just by swapping them. Everything's backed-up.
