Windows 10 External USB 3.0 Hard Drive Keeps Disconnecting and Reconnecting
Trying to store data or create an image backup and before you can start the external USB drive disconnects and File Explorer closes. Then a short time later the USB drive connects and File Explorer opens.
It’s an endless cycle of connect / disconnect and if your external USB drive has more than a single partition File Explorer will open multiple times, one for each partition.
My problem was an older 5400 RPM USB 3.0 drive and as I discovered specific to Windows 10 as I have Windows 7 and 8.1 image backups on separate partitions on the same USB drive.
To verify the problem was not specific to this Desktop computer, I removed the Windows 10 drive and installed a drive with Windows 7 installed (I have a front panel drive slot so no need to open the desktop case cover to change drives) and created a backup with no problems and since this is one of my oldest USB drives I sure there were no issues creating Windows XP backups or storing files.
Fortunately there is an easy solution: 1) In Windows 10 open the Control Panel: click on System and Security / Power Options / Change plan settings / Change advanced power settings / USB settings / USB selective suspend setting.
2) Click on the “Setting” drop down and change from “Enabled” to “Disabled”.
3) Click on the ‘Apply’ button and then the ‘OK’ button to make the change permanent.
4) Exit the Control Panel.
5) Now try creating an image backup. You can open File Explorer, navigate to the USB drive letter and open the USB partition and leave it idle (make no changes / save nothing). File Explorer should now remain open and the “Connect / Disconnect” issue should be resolved.
