I just installed an identical 500 MB WD hard drive that was designated E: on an XP SP3 machine. By the way, HD prices have tripled and a shortage is along the way. I want to clone my C: drive to this one for obvious reasons. I have some questions for those who have done this: 1. What is the easiest way of doing it? I have Acronis Home 2011 but I was never sure about its reliability. 2. If I clone to drive E:, I read some place that I have to remove it otherwise it will lose the data. Is this true? 3. Anything else I shoudl know? Thanks a lot guys. I appreciate your help.
