Device Management

3.1 Manually Unmounting Volumes

  • To ensure no data is lost during normal use, always eject or unmount the corresponding volume(s) from the operating system before powering off and disconnecting the device. Unmounting options are provided below.


  • Drag the icon for the device you wish to unmount to the trash can; OR
  • Right-click the device icon on the desktop, then click “Eject”; OR
  • Highlight the device on your Desktop and press Command-E.


  • Windows 10 build 1809 (October 2018) or later:
    • Eject the drive by clicking the ‘Show hidden items’ menu in the Taskbar, then clicking ‘Safely Remove Hardware and Eject Media’, and last select the ‘Eject’ option for this volume.
  • Windows 10 build 1803 and earlier:
    • Go to the System Tray (located in the lower right corner of your screen). Click on the “Eject” icon (a small green arrow over a hardware image).
    • A message will appear, detailing the devices that the “Eject” icon controls, i.e., “Safely remove...” Click on this prompt.
    • You will then see a message that says, “Safe to Remove Hardware.” It is now safe to disconnect the device from the computer.

3.2 Drive Removal and Powering Off Device

  • Power off a drive by pressing and holding the corresponding drive power button for three seconds. Release the power button after holding for three seconds.
  • Remove the powered off drive from the OWC Drive Dock after use. NOTE: If using a platter drive, ensure the drive has had a moment to rest after unmounting and power off. The platter may spin for a moment after use and removal of the drive while the platters are spinning may cause damage or data loss.
  • After drive usage is complete the OWC Drive Dock can be turned off by pressing the power switch to the off position. NOTE: When you use the power switch on the back of the Drive Dock to shut off power, the next time you switch the power on, neither drive bay will receive power. You will need to press the numbered power button(s) for the drive(s) you want to use during that session.

3.3 Usage Notes

  • RAID configurations are not recommended.
  • The OWC U2 Shuttle is not compatible with the OWC Drive Dock.

  • The two drives bays operate completely independent of one another. Users can unmount, power off, and remove one drive without affecting the other drive.

    • The LEDs will show blue when there is an active data connection, the Drive Dock is powered on, but no drive activity is detected.
    • The LEDs will blink blue and pink when there is an active data connection, the Drive Dock is powered on, and drive activity is present.

4.1 Troubleshooting

  • Begin your troubleshooting by verifying that the power cable is connected to the OWC Drive Dock and to a power source. If the power cable is connected to a power strip, make sure that the power strip is switched on. Next, verify that both ends of the data cable are properly plugged into the system and the OWC Drive Dock. If you are still having trouble, try connecting a different type of data cable and see if the Drive Dock works properly. You can also connect the device to a different system.
  • If issues continue to occur, please know that OWC support is here to help. Contacting support information can be found in section 4.4. Please have your serial number ready which is located on the bottom of the OWC Drive Dock and printed on the original packaging.
