Opps, Forgot to mention this.....

Yuki, you say:

The odds of both the internal and external going
down at the same time have to be pretty small I would think.  Not
impossible, but pretty small.

And yes I agree. But this is not the point of backup.......
What if, You accidentaly erase some important file in your system.
And I mean realy erase - Empty trash - And have done alot of disk writing 
since.

You think - Oh no worries - And plug your USB drive in.
Ah there's the file - Hmm, But the directories have some wierd glyphics in 
it....
Oh well - You go ahead and Copy the file. Pop it in it's proper place....
Well I guess you know the rest of the story..... You'd wanna hope that 3rd
USB drive you bought has some current data on it. ;-)
