I am building a second desktop pc and I intend to have my current one run off a 320gb toshiba hdd that is currently formatted but unused (windows will be installed on that) and the new one run on an ssd of yet undetermined size. The idea is I will use my current hdd (930gb, also toshiba) (after I relocate the os) as my primary storage for both pcs. Basically when I need to use one I just plug in the hdd and use it and when I need to use the other I just swap it over. I wanted to confirm if this is actually possible before I commit to it and relocate and install stuff.
