My Sony computer that I have had since 2000 or so is store bought and came with windows xp. I believed it had two hard drives in it until earlier this year when I found out it came with one partioned hard drive. I now have two physical HDD and three that appear on my computer. I need to restore my computer and would like to make my partioned drive appear as one. I will have all my backup files on my second physical HDD. If it makes things easier at all I do not have a windows install disc only system restore discs that came with my computer. If this isn't clear enough please ask me to try and clear it up.
