  • Hi,

    Before moving on troubleshooting, I suggest that you could check this issue in another working machine to determine whether this is an external hard drive related issue. If the this issue disappears, you could upgrade the USB controller on this machine. In case you use a NVIDIA USB EHCI chipset, you could try following hotfix:

    Otherwise, you could contact the manufacturer to check the hardware.
