First, i need to know for sure which type of hard drive that i have. will it be on top of the hard drive itself? (EIDI or SATA) Second, i want to take the existing info and copy to the new drive, once purchased. is that something that can be done? i dont want to go out and buy Microsoft XP when i already have it on my system. i want to put a larger internal harddrive in, and i need the info so i dont mess it up. i am a little litterate when it comes to computer stuff, but no a savvy tech like you folks n here. thanks for the help.
