This folder is empty

Question

Hi guys,

We have a Windows 10 Pro computer that for some reason seems to lose it's files on any attached USB drives.

At the moment if I select properties of the USB drive I see that the USB drive has 92GB used, but opening the USB drive itself all the folders are there but the files are not. I know it has Veeam backup files on it.

After rebooting the computer the files come back, but sometime during the day they will disappear again. It's all very odd!

Device Manager says that the Intel(R) Trusted Execution Engine Interface has the error STATUS_DEVICE_POWER_FAILURE.

In Event Viewer the logs say (Error) "The driver detected a controller error on \Device\Harddisk1\DR1" but changing the USB drive with any other USB drive results in the same message, so I'm inclined to think that it's an OS issue?

In Event Viewer I'm also seeing (Warning) "The Intel(R) Trusted Execution Engine Interface is being disabled."

Any ideas how I can fix this situation?

Hi Alex,

Thank you for writing to Microsoft Community forum.

• What is the make and model of the machine?

The USB 3.0 ports are under control of a controller xHCI, which also supports USB2 operations, but with a new xHCI driver. If the software for the old proprietary USB 2.0 device is written without regard for system driver device application interface and somehow expects specific old controller (EHCI), issues like this could occur.

Systems/Motherboards with USB 3.0 have xHCI configuration. You may disable the xHCI from BIOS, so that the on-board USB 3.0 port function like a 2.0 port and check if it works. To disable xHCI, you may get in touch with your system manufacturer.

Note:

• Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.
• xHCI Mode Disabled - The on-board USB 3.0 port functions like a 2.0 port.

xHCI Mode Enabled - The on-board USB 3.0 port functions like a 3.0 port.

If the issue persists, you may uninstall and reinstall the USB root hub and check:

• Right click the Windows icon on the taskbar and choose ‘Device Manager’.
• Expand Universal Serial Bus controllers.
• Right-click the affected USB Root Hub, and then click Uninstall to remove it.
• Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB root hubs that you uninstalled.

You may also run the troubleshooter to Automatically diagnose and fix Windows USB problems.

To resolve STATUS_DEVICE_POWER_FAILURE of Intel® Trusted Execution Engine Interface, you may try the following steps:

• Right click the Windows icon on the taskbar and choose ‘Device Manager’.
• Right click the failing driver and choose ‘Update Driver’.
• Click on ‘Browse my computer for driver software’ and select ‘Let me pick from a list of device drivers on my computer’.
• In the list of available drivers, choose the previous version and allow it to install.
