Hi, I was given a newer computer recently. My old one was full. I wiped it and started over, but it is an older unit and the new one is, well, newer. The hard drive on the old computer is a substantial size. What I would like to do is format the old drive, removing everything on it, including if possible the OS, and somehow use it as an external or secondary drive. I would run my recording software on the new computer and use the old drive to store all of my project files. I googled it, and all I get is "turn your old computer's hard drive into a portable drive", which is done by purchasing a particular case. I would rather just hook one computer to the next. Can I do this? How hard is this to do? And assuming I can do this without the OS installed on the old PC(old PC is XP, new one is Windows 7), this is the way I would like to go. Anyone know what I need to do? Thanks in advance.
