I guess I forgot to suggest the obvious, which is how I back up entire Rio Central hard drives. And that is to use Ghost software to clone the existing Central drive onto a new drive. A 40GB drive will take about 30 minutes to clone on my PC...

I could do it for you if you don't have the capability on your PC to do it. I have a special "Test-bed" PC that has an OS disk with Ghost on it and two empty drive bays for source and destination hard drives to back up....

Thanks, Randy
