I have a PC with a 2 disk raid array setup (Vista OS). It came pre-installed this way. One of the hard disks, the first disk in the array has failed and i am getting a replacement. The second disk works so I can access everything as usual, but my question is, when the replacement disk comes, how to I configure it back into the raid array. I dont want to wipe the good drive by mistake!
Thanks for any help you can give me.

Which version of Vista are you using?

It should be simple, as I assume it's a software array, using Mirroring (from the sound of it).
Unless, you have a hardware raid controller, then it is normally set up in the Bios, or an onboard utiltiy.

What is your computer?
