Get corresponding physical disk drives of mountpoints with WMI queries?

Question

Is there a way to retrieve a connection between a mountpoint (a volume which is mounted into the file system instead of mounted to a drive letter) and its belonging physical

Answer 1

The only way I know of is using the Win32 API to help.

You open a handle to the volume using Win32_Volume.DeviceID, modified slightly. You can open a handle to the volume using the format:

\\.\Volume{[GUID]}

You then need to issue IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS on the open handle to retrieve a VOLUME_DISK_EXTENTS structure. This structure will contain a list of physical disk ids for the volume.

Using these disk ids you can query WMI on Win32_DiskDrive.Index to get the matching disk.
