    External HDD turns off automatically


    Hello. I have windows 8.1 and I have noticed that my externall hdd turns off after a few mins of being idle (The led turns off as well.), but I can still see it on the windows explorer and it turns on again when I click on it.

    Is that normal ? It doesn't happen on Windows 7

    Thanks.

    I just did that and the external HDD still turns off after a few mins of being idle.

    What delay do you have the "Turn off Disk" set to for the power plan you are running? Is it set to "Never" (toggle down past zero to get to "Never")?

    The settings in Advanced Power will not actually shut off the power for the drive, it just sets it to an idle state. This is something else, the USB port - Turn off all USB selective Suspend Settings too:

    If yours is on, turn it off. it may be shutting off the USB port.
