I have a major problem. My Dell dimesion 4300 series computer has two disk drives C and E. However when I go into the C drives property it says the device is working properly but the device usage bar is blanked out and I cant click on it to disable it if I needed to. The reason I ask this is because I cant access some of my file on that drive nor does my camera or printer work and they are both connected through the usb port with their programs in the C Drive. Does anyone have the time to help me with this?
