I have an old 40GB 5400rpm hard drive. Id like to replace it with an 80gb 7200 8mb western digital HD. I dont want two hard drives, just the bigger faster one. My question is, is there a way i can copy everthing from my 40gb, (including the OS and all), to the 80gb one? this way i can trash the old one, or erase it and ebay the thing.
