I agree with The Other One...you should prob get a new hard drive. As for transferring everything, You could either just leave it as a secondary, or you could use a program, or you could just do "copy" "paste." that's my method

. Make sure though, if you're getting a new hard drive, that it's good. Lol, that was pretty vague. If you're going to use it as your primary drive, i'd say get one that's 10k rpm, if you can afford it. you should also make sure you get one with 16mb cache and, and of course, if your mobo supports it, sata (pref. sata2).
