mapping win32_logicaldisk to win32_diskdrive?

i am building an Adobe Air App where i can only fetch the "drive letter" of the particular usb thumb drive i am plugging in.

This drive can be easily also fetched with wmic logicaldisk where 'DeviceId="D:"' if drive letter is D:

But what i really want is to get the PNPDeviceID of Win32_DiskDrive class for the drive mentioned before.

As far as i can think , linking win32_logicaldisk and win32_diskdrive with some class in between would do the trick , yet i can't figure the way for it.

So i kindly request to put your expertise forward on this thread to solve this problem.

cheers

Found the Answer from here http://forum.exetools.com/showthread.php?t=11226

WMIC PATH WIN32_DISKPARTITION ASSOC <-- this command links win32_logicaldisk with win32_diskdrive in a weird but manageable way.

thanks for your help guys !

I believe you need two different WMI classes to derive this. First, Win32_LogicalDiskToPartition, to (obviously enough) map the logical disk to a partition. Then you can use Win32_DiskDriveToDiskPartition to find the physical drive holding that partition.
