Windows 7: webdav drive assignment got taken up by phantom CD drive

webdav drive assignment got taken up by phantom CD drive

Windows 7 Home Premium 64 Bit
Dell Inspiron 3487

Note: I generally use the freeware Alex Nolan DriveMan to see the current assignments.
My normal CD/DVD drive, the only one on the puter, runs fine on the F:, and shows up as about 3.4 GB.

I used the WebDav facility in DriveHQ to create an H: drive for the DriveHQ interface.

While DriveHQ has a very nice file manager, by using the WebDav assignment I could have Syncovery or any backup program work directly. That worked fine.

On reboot, I am shown the H: as now being a visible CD/DVD drive with no information and 0 bytes. Thus the WebDav attempt on initiating gets "The local device name is already in use".

Is there a reason why this CD/DVD phantom drive shows up? Is there a WebDav communicating with OS problem?

Afaik (checking visually, Driveman originally, Belarc, etc.) there really is only one CD/DVD.

Any help appreciated as to why this drive appeared, and my best plan of action. (Theoretically I could just change the WebDav assignment and see what happen. Or perhaps delete the CD assignment? However, I would like to get to the root of the issue.)

Just go to disk manager and change the drive letter to what you want it normally only changes if something new is added or removed

The phantomish drive H:/ does not show up in Disk Management. It does show up (but can not be accessed) as a CD Drive in Windows Explorer and Total Commander as well as the Alex Nolan utility. In Windows Explorer it is a second entry under "Devices With Removable Storage".

I wonder if somehow the WebDav info was misdigested. I will call DriveHQ support when they open this AM.
