Help Please. This request will indicate my knowledge is strictly limited. I have an ACER 5500Z that works just fine. The original config showed (and still does) two HDD's (C and D). My belief is that this is more a compartment config rather than two separate physical drive units. My C drive is almost full, my D drive is almost empty. How does one normally 'manage' this situation and gain more optimum use of the D drive ? Any help greatly appreciated. Many thanks in advance.
