    External HDD not mounting on boot (at times)

    Hello,
    I have a new problem since the upgrade to Bionic and it's that my external HDD doesn't seem to mount at boot as it should.
    For the last two or three times I started this box, I had to unplug-replug the power and/or the USB wire for Ubuntu to detect and mount the HDD unit.
    I've had the HDD for almost two years, and with older versions of Ubuntu had some mounting problems, but now they are increasing in frequency.
    The HDD needs external power and the USB plugs at both ends. I can't see a problem with loose connections.
    This is the lsusb output -now that it has mounted correctly.

    Does anybody know how to make the mounting of this HDD work by default at startup? Or does anybody know why is not mounting at times?
    Thanks.

    Re: External HDD not mounting on boot (at times)

    I have also seen what you are experiencing since kernel 4.15 and newer.
    It seems in my case if I opened "gnome-disk-utility" and clicked on the effected Disk or partition, and then below the window you will see a double cog, select that>>>choose "Edit Mount Option"
    Then deselected the "Default Session Default" >>>Then checked the box "Mount at system startup"
    And yes that Drive is also a USB external drive.
    Code:
    $ pinxi --usb
    USB:
      Hub: 1:1 usb: 2.0 type: Full speed (or root) hub 
      Device-1: Logitech Unifying Receiver bus ID: 1:2 type: Keyboard 
      Device-2: Realtek Mass Storage Device bus ID: 1:3 type: Mass Storage 
      Device-3: Intel bus ID: 1:4 type: Bluetooth 
      Device-4: Linksys WUSB100 v1 RangePlus Wireless Network Adapter [Ralink 
      RT2870] 
      bus ID: 1:5 type: Vendor Specific Protocol 
      Device-5: JMicron / JMicron USA ATA/ATAPI Bridge bus ID: 1:6 
      type: Mass Storage 
      Hub: 1:15 usb: 1.0 type: Genesys Logic USB 1.1 Hub 
      Device-6: Logitech Unifying Receiver bus ID: 1:16 type: Keyboard 
      Hub: 2:1 usb: 3.0 type: Full speed (or root) hub 
      Device-7: ASMedia ASM1051E SATA 6Gb/s bridge ASM1053E SATA 6Gb/s bridge 
      ASM1153 SATA 3Gb/s bridge 
      bus ID: 2:2 type: Mass Storage
    And my disk layout:
    Code:
    pinxi --D
    Drives:
      HDD Total Size: 4.55 TiB used: 373.06 GiB (8.0%)
