Hi all.
My powerbook is giving me nothing but a grey screen. I ran Disk Utility off of the OS X CD on the HD, and this is the message it gave me:

Checking HFS volume
Checking Extents Overflow file
Checking Catalog file
Invalid node structure.
Rebuilding Catalog B-Tree
The volume Macintosh HD could not be repaired.
ERROR: The underlying task reported failure on exit.
1 HFS volume checked--1 volume could not be repaired because of an error.
Repair attempted on 1 volume--1 volume could not be repaired.

I also tried whatever is on the AppleCare CD (can't remember), and it put a bunch of gobbledy gook on the screen, gave me a restart message, and at the very end said "panic: we are hanging here..." (insert twilight zone music here).

I'm guessing all this means my hd is kaput. Is there anything else I can try?

Also, I've looked into replacing the hd myself using instructions on ifixit. It doesn't look too difficult. Does anyone think this is an awful idea?

    This might be something that Disk Warrior can fix. However, if it is a mechanical problem, you should try to recover your files from your dying HD, using Data Rescue II and another external HD.

    A B-tree error is an error in the data structure of the hard drive. Usually, Disk Warrior or TechTool Pro can fix this sort of error (you can go to their web sites and search their support section to confirm). It is possible that the hard drive itself caused the error. In that case, if it passes the hardware test and has a good SMART status, doing a security erase where you write zero's on the hard drive will both ensure you have a clean drive to start with, and that function also updates the bad block table on the hard drive. If bucks are a consideration, a new hard drive, depending on size, can be less expensive than Disk Warrior or TechTool Pro, both which list for around $99.
