I have an older Pentium 4 computer with extremely valuable CAM software (worth about $20,000). The software has been installed on an IDE hard drive and I need to upgrade the OS to Win7 (or at least Vista) in order to have access to our new file server. Upgrading the mobo, cpu, ram, etc is simple, but how do I make a perfect copy of the old IDE hard drive on a newer SATA drive to help system performance? I'm new at this, so I will need step by step instructions please. Any help is greatly appreciated.
