I need to move a factory installed 20 GB hard drive from a 400Mhz Power Mac G4(AGP graphics) to a Dual 1 Ghz G4 becuase evidently the motherboard is bad in the old comp. I've never installed another hard drive before so I was wondering what problems I'm likely to run into? Both of the hard drives are startup disks so will that cause a conflict? Any easy instructions for doing this on the internet that I could print out? I really need to install it to retrieve data but after I get that would it be worth it to keep it around in my comp or is the hard drive to old to be worth it? Sorry for the newbie questions but I don't want to hurt my comp cause its my baby! Thanks for to anybody that reads this and replies.
