surge usually occurs when there is no power supply with the USB Hub. If this is the case, there isn't enough power to run the HDD's data I/O. It's all in the voltage. All my hubs (8 at last count) have their own PSUs. The voltage from the motherboard may also be a factor.

Like many others I do receive the same error of a power surge and I do have SP2. The question I have is this. I can have my printer and wireless keyboard plugged in and they work, still get the error, but they work. When I remove one or both ports and plug in my external hard drive it freezed my computer. Why?
