I call it drive letter or mount point. I've shown the
relation between a drive letter and storage volumes
in a sample (user mode):

Match the DeviceNumber you get for the drive letters with
the DeviceNumbers you get in the SetupDi enumerations
of GUID_DEVINTERFACE_DISK, GUID_DEVINTERFACE_CDROM or
GUID_DEVINTERFACE_FLOPPY.
It's all shown in the sample.
