So I'm hoping this will be very easy because my drive that failed is not part of my mirrored set. I had my OS drive go bad but my data drive ( my 2TB mirrored set ) is still ok. I just can't access it. I'm going to rebuild my OS ( switching from WinXP to Win7 ) for the rebuild. I just thought I should ask about any gotchas anyone might have run into because that mirrored set holds all my pictures and such so its very sensitive.
