Hello, Before I fork out money on what seems like it could be a good product I wish to know if I can backup my entire c: drive - a 20 gig drive running Windows XP, and then restore this drive to a new hard drive that is not the same make OR size. The reason I ask this, is because Microsoft officially says that Windows XP will NOT install if it detects any changes in hardware. If I upgrade to an 80 gig drive but the image was made from my 20 gig, will the image work ? or will Windows XP hiss and spit at me and tell me that hardware has changed and then refuse to install ... ? I don't find the website very informative on this subject. My 20 gig drive is a Maxtor and I may buy a WD brand drive, - will just this alone make the image not work properly because XP decides my hardware is NOT the same and so refuses to run ? any help appreciated for a newbie.
