I have got a new hard drive that I'd like to merge with the one I already had. And I need your help to do this. As you can see there is two physical hard drives, and I want to merge the partition of the new one to the old one, making it one big partition.
You can't do that without setting them up in a RAID array which requires a RAID controller. Your motherboard might have one otherwise you'll need a PCI one.
