FCC Statement:
Warning! Modifications not authorized by the manufacturer may void the user's authority to operate this device.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause harmful interference with radio commu-
nications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will
be required to correct the interference at his own expense.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference with radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
Health And Safety Precautions:
• Use proper anti-static precautions while performing the installation of your hard drives into this drive enclosure. Failure to
do so can cause damage to your drive mechanisms, and / or the hard drive enclosure.
• Read this User's Guide carefully, and follow the correct procedure when setting up the device.
• Do not open your hard drive or attempt to disassemble or modify it. Never insert any metallic object into the drive to avoid
any risk of electrical shock, fire, short-circuiting or dangerous emissions. Your hard drive contains no user-serviceable parts.
If it appears to be malfunctioning, have it inspected by a qualified Other World Computing Technical Support representa-
tive.
• 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:
• Do not expose the enclosure to temperatures outside the range of 5° C to 40° C (41° F to 104° F). Doing so may damage
the drive or disfigure its casing. Avoid placing your drive near a source of heat or exposing it to sunlight (even through a
window). Conversely, placing your drive in an environment that is too cold or humid may damage the unit.
• Always unplug the hard drive from the electrical outlet if there is a risk of lightning or if it will be unused for an extended
period of time. Otherwise, there is an increased risk of electrical shock, short-circuiting or fire.
• Use only the power supply shipped with the device.
• Do not use the hard drive 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 drive near sources of magnetic interference, such as computer displays, televisions or speakers. Magnetic
interference can affect the operation and stability of your hard drive.
• Do not place heavy objects on top of the drive.
• If you detect a problem, consult the Troubleshooting section in this manual.
• Protect your hard drive from excessive exposure to dust during use or storage. Dust can build up inside the device, increas-
ing the risk of damage or malfunction.
• Other World Computing recommends the use of normal glass cleaning products to keep the high lustre finish at its finest
with this product. Be sure not to get any moisture inside the holes and if you do, allow time to air dry before use.
• Do not block the ventilation outlets on the front of the drive. These help to keep your drive cool during operation. Block-
ing the ventilation outlets may cause damage to your drive and cause an increased risk of short-circuiting or fire.

I have pulled out my OWC Mercury Elite-AL Pro from storage and when I try to connect it to my new M4 Macbook Pro via USB it is not recognized at all.

If your OWC Mercury Elite Pro is not recognized by your M4 MacBook Pro when connected via USB, consider the following troubleshooting steps:

1. Check Cables and Ports – Ensure all cables are securely connected. Try using a different USB cable or port to rule out connection issues.
2. USB Compatibility – The OWC Mercury Elite Pro Quad supports USB-C and includes a USB-C to USB-A cable for compatibility with older machines. Verify that your MacBook Pro supports the connection type being used.
3. Disk Utility Check – Open macOS Disk Utility to see if the drive is detected. If it appears but is not accessible, try using Repair Disk and Repair Permissions in Disk First Aid.
4. Formatting Issues – The drive may be formatted using a partition scheme incompatible with your Mac. If necessary, reformat it using Mac OS Extended (Journaled) or APFS in Disk Utility.
5. Power and LED Indicators – Check if the drive's LED indicator lights up when connected, which confirms power and activity.
6. Try Another Computer – Connect the drive to another Mac or Windows PC to determine if the issue is specific to your MacBook.
7. Software Conflicts – If using RAID configurations, ensure that required drivers or software (such as SoftRAID) are installed and compatible with macOS.
8. Firmware or macOS Updates – Ensure your MacBook Pro is running the latest macOS version, as updates may improve hardware compatibility.

If the drive is still not recognized after these steps, contact OWC Technical Support for further assistance.
