I have a Maxtor 5000Le 80GB external unit. I am running Windows XP Pro. I've had this unit for years and it has been great. About a month ago my computer locked when booting and after checking out all my external hardware, I found out that this unit had caused the problem. It seemed that the usb port or the cable was the problem. When I unplugged the usb, plugged it into another port, and even replugged it into the original port all of a sudden it started working again. It has been working fine since then until today. . . Now the problem is: . . . . Windows boots just fine. . it just doesn't recognize this external hard drive at all. The hard drive is not making any noise at all, the green light on the unit is turned on showing that the unit is powered up. . .just no noise. I tried it with a new usb cord and still nothing. It's like an internal switch is out or maybe the internal usb connector on the unit is damaged or something. Please help. This unit has years and years of information in it and I really need to be able to get to it.
