By default in Windows 10, USB devices are put into a selective suspend mode to help save power. When the DataLocker device detects this cut in power, the drive instantly times out and locks the drive to prevent tampering. This usually happens anywhere from 2-10 minutes of inactivity on the device, and it also bypasses any inactivity lock set directly in the device's menu. This guide will show how you to disable the power save feature within Windows 10.


Note: this only impacts devices that do not have a software client that needs to run on the host computer to unlock the device.
