External Drives Randomly Unmounting

I'm having an issue where my external drives in Unraid are randomly being unmounted. As a workaround to this, I have to go into the terminal, unmount them with the umount command, and then mount them again via the web interface. It occurs about every few minutes. I've checked connections and tried different ports without success.

    Try a different USB port or a different USB bridge, this is unfortunately typical with some USB devices.

    Thanks for the suggestion. I tried different ports with no luck. It seems that my motherboard might be faulty as I recently upgraded it.

    USB drives and Unraid are a hit and miss combo.  Cautious to write the MB off as bad in your scenario.
