Hi Ken,
Thank you for the updates.
Since the issue persists, let’s try the following steps and check.
Method 1:
You may perform a clean boot and check if it helps.
A clean boot helps to verify if any third party application services or startup item is causing this issue.
How to perform a clean boot to troubleshoot a problem in Windows Vista, Windows 7, or Windows 8
**Note:**After you have finished the troubleshooting, refer to the section “How to reset the computer to start as usual after troubleshooting with clean boot” to boot the system in normal start up.
Method 2:
You may try performing a SFC scan on the computer which would scan for corrupt system files on the computer and replace them.
Method 3:
You may also check if you can perform the backup to a different location or on a different drive.
Also make sure the Kingston Micro stick works fine on a different computer.
