2.2 Usage Notes

3.1 Troubleshooting

Begin your troubleshooting by verifying that the power cable is connected to the Mercury Pro and to a power source. If the power cable is connected to a power strip, make sure that the power switch on the strip is turned on. Next, verify that both ends of your data cable are securely plugged into the computer and the Mercury Pro.

If the Mercury Pro is still not working properly, try using a different USB cable. You can also connect the Mercury Pro to a different computer to eliminate the possibility that the problem is with the computer and not the drive or the cable. If problems persist, please contact OWC Support.

3.2 Ejecting Discs

OS X / macOS

  • Drag the desktop icon of the disc to the trash.
  • Open a Finder window, then click the eject button next to the disc icon (located under ‘Devices’ in the sidebar).


  • Press the ‘Eject’ button on the front of the unit.

Health And Safety Precautions

  • Read this guide carefully and follow the correct procedures when setting up the device.
  • Use proper anti-static precautions while performing the installation of your drives into this drive enclosure. Failure to do so can cause damage to your drive mechanisms and/or the drive enclosure.
  • Do not attempt to disassemble or modify the device. To avoid any risk of electrical shock, fire, short circuiting or dangerous emissions, never insert any metallic object into the device. If it appears to be malfunctioning, please contact OWC Support.
  • Never expose your device to rain, or use it near water or in damp or wet conditions. Never place objects containing liquids on the drive, as they may spill into its openings. Doing so increases the risk of electrical shock, short-circuiting, fire or personal injury.

General Use Precautions

To avoid damage, do not expose the device to temperatures outside the range of 5° C to 40° C (41° F to 104° F). Always unplug the device from the electrical outlet if there is a risk of lightning or if it will be unused for an extended period of time.

  • Do not use the device near other electrical appliances such as televisions, radios or speakers. Doing so may cause interference which will adversely affect the operation of the other products.
  • Do not place the device near sources of magnetic interference, such as computer displays, televisions or speakers. Magnetic interference can affect the operation and stability of drives.
  • Do not place objects on top of the device.
  • Protect your device from excessive exposure to dust during use or storage. Dust can build up inside the device, increasing the risk of damage or malfunction.
