Translate Hard drive letter into the corresponding Device ID (or viceversa)

I need to Identify the drive letter of a Manufacturer ID of a hard drive device (or maybe viceversa thing I could do it too).

The command to retrieve the manufacturer IDs:

WMIC.exe DiskDrive Get /Format:List

Example Output (splitted and with HTML entities formatted):

PNPDeviceID=DISK&VEN_WDC_WD10&PROD_02FAEX-00Z3A0

The command to retrieve the drive letters:

WMIC.exe Volume Get /Format:List

Example Output:

DriveLetter=C:

The problem is that I can't find any useful property that I could associate from both outputs to make a query, I mean I don't know what to do with the manufacturer IDs to search the drive letter of each ID, I can't see any way to identify the drive letter of the ID.

So at the moment that I get the DeviceID DISK&VEN_WDC_WD10&PROD_02FAEX-00Z3A0 I need to translate it to the equivalent driveLetter, which is C:, that's all.

I've tried using WMIC tool 'cause I don't know how to associate this info using native commandline tools provided in Windows, but really is not full necessary for me to accomplis this task accesing to WMI Classes, I could accept a solution using other presintalled tools in Windows (maybe BCDedit?), or a solution in VBScript language should be accepted too, but for environment circunstances I can't do this task in any other languages (included native PowerShell) and also not using 3rd party tools like Devcon utility provided by Microsoft.

The reason why I need that is to finish this Script which should retrieve and exclude the DeviceID of the DriveLetter C::

@Echo OFF & REM Mode con cols=150 lines=50

:: Exclude this drive during the process.
Set "ExcludedDrive=C:"

:: This variable should be set later,
:: Stores the device ID of the drive letter excluded above.
Set "ExcludedID="

Solution to get the Device ID of the Hard drive that stores the System (C:)

@Echo OFF & Setlocal EnableDelayedExpansion

(
 REM Diskpart Script to get details about the System's Hard Drive.
 Echo Select Disk=System
 Echo Detail Disk
) > "%TEMP%\Diskpart.tmp"

For /F "Tokens=*" %%# in (
    'Diskpart /S "%TEMP%\Diskpart.tmp" ^| Find /I "Disk Device"'
) Do (
    For /F "Tokens=1,2,* Delims=\ " %%a in (
        'WMIC.exe DiskDrive Where Model^="%%#" Get PNPDeviceID /Format:CSV ^| Find /I "&"'
    ) Do (
        Set "DeviceID=%%b"
        Set "DeviceID=!DeviceID:&=&!"
    )
)

Echo "!DeviceID!"
