Raid 1 increase capacity with new drive

[MN Scout]

I had a raid 1 set with two 250Gb drives. One of the drives died and I purchased two new 500Gb drives and would like to increase the capacity from 250Gb to 500Gb. I am using NVRAID on my A8N-SLI Premium motherboard.

When I just put the 500Gb drive in there nvraid rebuilt it, and then when I took the 250Gb drive and swapped in the second 500Gb it then rebuilt it a second time but the capacity stayed at 250Gb. It did the rebuilding automatically in Windows.

What is the proper way to do this? Do I need to take one of the drives out of the array, format it, and clone the Windows installation onto the larger drive, and then re-setup the array?

I think that would work. You could also use a tool like PartedMagic to resize the partition, but the array is probably not accessible from the Linux environment.

Windows only sees that the raid is 250Gb; it doesn't see that there is another 250Gb free there so I'm thinking something like Partition Magic isn't going to work.

Right now I moved one of the 500Gb drives off of the Nvidia controller and onto a Silicon magic controller. I'm reformatting it, and I'm going to try one of the cloning tools.

This is taking a lot of time.
