I get this at boot and when restarting the Microsoft Exchange Diagnostics service ever since I updated to CU7.  Anyone know anything about this?

Same here.

One clean install of CU6, two clean installs of CU7.

This seems to be resolved my issue:

I am getting the same issue with CU8 as well so not fixed in CU8 too. Please update if someone is able to fix it.

Hey all,

I know this is not a "fix" but it will stop the events from appearing.

In the Microsoft.Exchange.Diagnostics.Service.exe.config file, usually located under: C:\Program Files\Microsoft\Exchange Server\V15\Bin\, change the DriveLockCheckEnabled to false.

<add key="DriveLockCheckEnabled" value="false" />

Restart the Microsoft Exchange Diagnostics service.

Hope this helps :)
