Ok by now you all know about my sad old puter...but it's all we got so I make the best of it. In my junk excursion a week or so ago I salvaged a Western Digital HD 2.2Gb, the same brand in our puter now,8.?Gb. I was thinking with us starting this new business I could install the other Hrad Drive to save documents & such on. There is a seperate harnesss already in the tower but I need to know how to keep the 8.1 Primary, & hook up the second, plus will I need to do anything different with the CD since it reads as slave drive on start-up. Thanks!!
