I have Win 7 installed on my current computer, but I also have my old Win XP install for the same computer on another HDD. I would like to hook up the Win XP drive as a secondary drive, to access the other data that's on it. My concern is that the two OSs will conflict with each other and possibly cause corruption. I would like it to just function as a data drive, but with the possibility of using the XP install again in the future. Is there any way I can temporarily "disable" the XP install? I hope that made sense. Thanks for any help.
