Why a USB external drive will only work when connected to a usb certain prot on my pc?
I have a usb external hard drive. I have opened many USB 2.0. This unit will only work from certain ports. Any reason for this?
may depend on where the USB ports are sometimes.ie Sometimes the back behave unlike any in the front (as run from a USB head) for power supply in the front are low. Another possibility is defective USB ports …. No other items have the same problem? if so defective ports. Another issue is that power USB devices msot drain any power from the USB and has a cap so that each pair of ports usually given only if 500MA device and drains all the other issue to have problems. without knowing the motherboard I can not give any additional information.
