Invalid B-Tree Node Size

in Genius Bar edited January 2014
Just got the dreaded B-Tree Node size error

My question is what do you recommend to fix it? is it fixable?

I've heard DiskWarrior has had some success..

Is it worth the 100 bucks?

    Dunno, how much is your data worth to you?

    For me, DiskWarrior is a freakin' *bargain*, and I always have a backup CD in my satchel. (The original stays at home, protected.) It's saved my butt more than once.

    Ditto Kickaha, Disk Warrior is worth every penny. An invalid B-tree node is probably repairable, and DW can probably fix it. However, nothing can protect from a head crash or the controller card writing garbage, or the motor burning out, etc. You gotta have a backup!
