If you are lucky, you could possibly clone the bad drive and copy the data over to the good drive. However, with it clicking, it will most likely fail sometime during creating the drive image. Also, I don't know if cloning works with a drive that was striped. But I don't see any reason for it not to.

A program I like to use for cloning/imaging drives is Acronis True Image. It's probably the simplest to use that I've had experience with. What you would do is install the good SATA drive into your computer, then run Acronis (or some other cloning tool) and clone the bad drive to the good drive. Then when it's done, just take out the bad drive and the new drive should have exactly the same data as the old one.

But again, with it clicking, I would bet it would fail during the clone...if it even recognizes the device anymore.

You may just have to format, take out the bad drive, install the good drive, and start over from scratch.

Hope that helps
