I have generic computer with a 20GB hard drive. I want to install a new, bigger hard drive but want to keep all of the information on the old hard drive. How do I do this? The computer is a CTX with an AMD Athalon processor and runs Windows 98. Need detailed instructions. Where to put new hard drive, what cables to connect? What do I do when the computer is started back up etc. There is a big enough space above the present hard drive to set the new in there. Be detailed with step by step instructions. I don't know much but I can follow directions. Thanks guys!!
