Hey everyone I am planning to build my own computer and plan to keep my original hard drive from my older computer because I still have an extra 60GB in it that are free and I wanted to know if I should back that up to be on the safe side. Also, since the operating system on there is home edition and it was an E Machine computer I would imagine that the OS won't work on this new computer that I am building, correct? What type of program would be good to use or what kind of cds should I back it up to? Is there anything else that I am forgetting or any other tips or hints to offer? Thanks so much for the help.
