Hey guys, I'm aware this may very well be a very basic question, but i'm going to ask it anyway, before i go ahead and commit myself to it later this morning. I'm putting in my new WD 500GB SATAII (5000AAKS) hard-drive tomorrow in replacement for my old 80GB SATA Maxtor HD. I'm hoping to see a big performance increase! Anyway, i'm stuck on backing up all my old files from the Maxtor because; A) My DVD-R drive blows and won't work. and B) Network seems to not be responding, so can't copy across any files to my old mans PC. So i'm sitting there stuck, with at least 10GB's worth needing to be backed up. My old man comes in and suggests i unplug the old 80GB, plug in the new 500GB and set it to 1st Boot Device in Bios, setup windows and get it all up and running. Then, plug in the 80GB HD, set it to 2nd Boot Device in Bios, delete windows and then simply copy across the files from the 80GB to the 500GB, using the 80GB as just a dud hard-drive. I've never done this before, and while it may seem basic, i just want to know if this is possible - if so, is there anything i should know first and will it have any performance impact on my PC at all? Cheers all! Hux.
