Hi Emmanuel,

I think the Live CD is a great suggestion. I was just thinking though. do you 
know of a Live CD that has XFS utilities on it? From what I've seen, I've had 
to install XFS utilities after installing the OS, which I don't think one can 
do with a live CD. I can look, but if you know of one, that would probably save 
some digging.

thanks,

Eli
