Hello, I'm seriously thinking about cleaning my computer: installing XP again, installing all the software needed, setting it up, and making an image of the disk so i can return to this state. I'll be using an external Hard Drive. As i'm not very knowledgeable, i have some doubts that can look silly , but i have to ask, to understand the concepts: 1- Reformatting the disk clears everything? Even malware? (not concerned with the latter, but i have to understand the process) 2- With Acronis True Image 10, for instance, i create an image of the HD. So if i clean everything, i can still use the image? Or are there things that can't be erased, i would have to use the XP CD/ recovery CD? (is everything in the image) 3- As i don't need to do anything else other than image the whole HD (to back up files, I can copy them to the external HD), what are my best options? Aditional features are OK, and i can change my mind. Best free and paid. I’m very interested in Acronis’s products, but confused with the differences. Is TI the best for me, or Migrate Easy? 4- What’s the difference between cloning and imaging? Cloning transfers the image from 1 HD to another and erasing the original? I know there must be other threads that approach this. Just try to explain these concepts, and give me links if you must. Thank you! PS. I haven’t bought the HD yet, any suggestions? Money is not much of a problem, as it is a good investment. But it must be a good HD in terms of quality/price ratio.
