Thread: External HDD only detected on 1 of usb ports

  1. #1

    Default External HDD only detected on 1 of usb ports

    It used to work in summer (approx. in July), and it worked in another linux distro I've been using for a while, however now only 1 usb port out of 3 works for my external harddrive.

    Logs for 'good' usb port:

    Google suggests that it might do with usb power saving (not enough power to spin up disk), so I've tried to disabling the feature overall (using /etc/default/tlp) for debug purposes, didn't change anything.


    Any suggested course of action? Its not really comfortable to exclusively use this exact port every time I need to connect my HDD.

    Hi
    Either use a powered hub, usb y-cable or a disk caddy you can hook a power pack to... sure it use to work, it's probably been detrimental to the hardware over time and components may not be able to provide enough power now... what are the WD drive specs? At best one port 500mA that's why consider at least a y-cable.

    Thanks for the answer! That sounds unfortunate.
