Not really a raid type person
My solution - cracking a nut with a sledgehammer perhaps.
A desktop with two 2tb drives - one is a clone of the original drive before any corruption (I use a free acronis). However I also regularly save any important data to the cloned drive.
I also save all data to a third usb independent drive (amongst other drives - I'm scared to death about loosing my Wife's photos)
My first drive has become corrupted once and I recovered it by cloning it back to the original 'cloned disk', complete with all data. Then I just had to update the disk with windows update etc.
Not very clever perhaps but it seems to work for me.
