I'm using BGInfo to dump the values of several parameters on the desktop background. One of the parameters I use is <Free Space>. I've noticed on a couple of machines (Windows 10) that my report produces the line "V:\(unrecognized). There is
no V: drive to be seen in the Disk Management app. However, if I try to change the drive letter of an existing drive to V I notice that "V" is not available for selection in the drop-down menu. What is the source of this anomaly and how do I get
rid of it?
