There are a couple of reasons why this may occur.


1. Low power from USB ports:


     - If using a workstation, try using the ports at the back of the system

     - Connect to a USB 3.0 port if possible

     - Use a powered hub to connect to the USB port

     - Try plugging the drive into a computer using a Y-Cable

     - Try using a micro-USB (type B) to test for bent pins that aren't allowing for power to be received 


2. Security software is interfering with drive communication (This occurs often with McAfee anti-virus software):


     - Allow list the drive (exclude the drive in the security software console). For a comprehensive guide to allowing DataLocker devices in your environment, please see here.
