Drive Checker For OS X

[slughead]

I have reason to believe one of my hard drives is messed up. It's not clicking, but it's having problems transferring large files.

It's currently in an ATA -> FW800 enclosure, could that have anything to do with it?

Regardless, I need to stick this in a G4 and check out these things to make sure they're OK.

Disk Utility shows nothing wrong, now I need to find something that will give me some real information (sorry Apple, your first aid never was that good).

I need something that will get down and dirty--get to the farthest depths of this damn hard drive to see if there's anything going on.

It's a western digital 250GB Caviar drive, by the way.

Restart your computer and hold command-s to boot into single user mode.
When you get to the unix prompt, type "fsck -f"
Let it run. If any errors are found, run it again.
Keep running it over and over until no errors are found.
Finish booting up by typing "exit", or restart with "reboot".

I personally love DiskWarrior,
I would stay away from Norton. Norton has messed things up made on macs before. Its a pile of poo. I found disk warrior was able to fix drives that norton refused to even recognise. If you don't want to spend any money then i'm affraid your choices are limited. And i wouldn't dare try any freeware how good is it if its free?
