that makes sense, these power supplies are WAY small.

I tend to not trust stuff that comes from Symantec with something so 
critical. In the old days they put out good product (mostly), now I think 
they are too big and commercial and have taken the Microsoft route "release 
it, the customers will find the bugs". I use their products, and they are 
mostly good and reliable, but with something like my RAQ hard drive, I 
won't trust it. Maybe I'm just being silly.

From Gerald's post:

Does this take care of all mkfs issues, or do I have to "make" a drive 
first? Is dd like a "real" mirroring system where it will take a drive out 
of the box and just do it?

Thanks. This is easier than taking out the drive, making the mirror, and 
putting it back.
On the subject of the small power supply, on a RAQ3i, would it be prudent 
to leave this spare drive unplugged unless it is necessary? Can the power 
supply handle 2 drives to even do the setup?

Again, thanks,
