USB no 5V - hdd connection impossible

Tone

Hi,
Im having between 4,86 - 4,74 V (which is out of spec) on all my usb ports (no other peripherie are connected to the upboard).
However, this is too less voltage to any of my hdds, even these with external power.
How can I fix this?

Check whether your power adapter's output voltage is less than 5V.
