3.1 Troubleshooting

If your computer does not recognize the drive when it is connected, make sure the 

Thunderbolt 3 cable is attached securely. You can also try plugging the cable into a different 

Thunderbolt 3 port on your computer and/or trying a different Thunderbolt 3 cable. 

If you are still having trouble it is possible one or more installed drives were not seated 

properly. Please use the steps shown in Section 2.1 to check the drives and make sure 

they are seated properly. If you continue to have trouble please see Secton 3.3 below for 

assistance in contacting Technical Support.

3.2 About Data Backup

To ensure your files are protected and to prevent data loss, we strongly suggest that you 

keep two copies of your data: one copy on your OWC Express 4M2 and a second copy 

on either your internal drive or another storage medium, such as an optical backup, or on 

another external storage unit. Any data loss or corruption while using the Express 4M2 is the 

sole responsibility of the user, and under no circumstances may OWC, its parent, partners, 

affiliates, officers, employees, or agents be held liable for loss of the use of data including 

compensation of any kind or recovery of the data.
