Does anyone know what "\?\Volume...." is or why it would be listed as a disk on the windows defragmenter?
It is not listed on other defragmenters like defraggler.
The E: and F: drives are mirrors.
Listing for HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\ . There were many other entries with similar naming but they were removed after using the application suggested by Psycogeek.
I removed the keys as Psycogeek suggested but they repopulated as a different alphanumeric string labelled as "Never run"
