I have an external 1Tb hard drive that is 94% full. I took it off and put it and a 2tb on my computer and copied the partitions to the 2tb. It works but the 3 partitions came out the same size. In other words I have a 1tb copy. I can not find any partition program to expand the 900gb unused partition on the 2tb drive. So I have a 2 tb drive with a 900gb program partition. Does anyone know how to expand that partition into the unused partition or re copy the old drive and have it expanded as I copy it?
