Ok no problem, not a big loss, by the way last time I tried to put a new hard drive I was following the wiki and I didn't do this step
9.Put a check in the Yes, I'm sure checkbox (next to the information indicating the drive will be rebuilt), and click the Start button
I didn't see any chechbox with this option, only one saying to format the drive(I didn't clicked it), I missed something? Next week I'll try to add again my bigger drive and I want to be sure I do everything correctly
