Your volume should go degraded (missing hard drive) and a rebuild to the spare drive should begin automatically. Remove the remaining 300GB hard drive.Once the rebuild is complete and the volume is normal again, attach the remaining 1TB hard drive and mark it as a spare.Attach one of the 1TB hard drives and mark it as a spare for the RAID 1 volume (open the console, right-click on the new hard drive and click Mark as Spare).If it doesn't include ICH10DO, you will need to create a second volume to use the additional capacity. Volume capacity expansion is supported on platforms with the Intel(R) ICH10DO controller hub, but I'm not having much luck finding a website that says what controller is in your system. Unless you can expand the volume capacity, the only way to use the additional space would be to create a second volume using that space.

There is no direct way to upgrade both your hard drives, but you should able to do it indirectly using the below steps.įirst - a caveat: the volume size will remain the same.
