I've got this WD 500 gb Firewire  external My Book drive I've been
using to store mostly video files for a big video project. It doesn't
have an on/off switch, it powers up when power is first applied, goes
dormant after a period of inactivity and restarts when you try to
access it. It's worked flawlessly until today.

Normally the blue light in front dances up and down during boot up as
well as whenever there's data transfer but now I notice the light
flashes briefly when power is first applied, the drive makes some
noise like it's starting to spool up but then shuts down. The couple
of h/d's I've had die in the past gave me some warning, made weird
clicking noises for a while before crapping out. This one was working
perfectly normally until now. I wouldn't think overheating would be an
issue with this drive, the case is extensively vented unlike most
external drives I've seen. It doesn't get used that much.

Anyone have experience with these drives? Any chance there's a power
supply inside the case that's causing the problem and can be swapped
with another from an identical drive? Would be a huge
Aaaaargggghhhhh!!!!!! to lose the hundreds of gigs of files. Any
chance WD would do such a repair?  I don't want another drive, I need
THIS drive to work.

Thanks for all assistance.
