Invalid B-Node Tree

A hard-disk failure strikes again, on another La-Cie disk, which is the main disk for a hip-hop documentary I'm editing. S! H! I! T!

The drive powers on, and it is recognized by Disk Utility but fails to repair it because of "invalid B-node tree error." It's a hardware failure, which puts the data within the disk at the precarious state. Since the disk didn't TOTALLY fail on me, I decided to get Disk Warrior 4 for $99.95, + $8 for shipping and handling.

After downloading the program and running it, it managed to salvaged the directory and the data, perhaps, by putting it on 'Preview Directory.' Since I don't have extra 500G around after dumped with a couple of hours of DVCPRO HD footage recently, I'll have to ask my director/producer to get another external hard disk and backup immediately.

Technical failures like this drive me to get big-ass Raid hard disk with redundancy, mirrored, disks for editing workhorse disk. (That's after I get a big-ass project with a big-ass check, I suppose.)

Cross your fingers, pray hard, and hopefully I'll get back with the good news of how I managed to recover 500 Gig of footage that my producer/director shot over a year. Sigh.
