Exetools - A drive letter is related to which physical disk?!

you dont need r0 to get all these information

simply start wmic in cmd.exe

and get all the information you need

Code:

wmic:root\cli>path Win32_DiskPartition get Deviceid

DeviceID

Disk #0, Partition #0

Disk #0, Partition #1

Disk #0, Partition #2

Disk #2, Partition #0



wmic:root\cli>path Win32_logicaldisk get Deviceid

DeviceID

A:

C:

D:

E:

G:



wmic:root\cli>path Win32_diskdrive get Deviceid

DeviceID

\\.\PHYSICALDRIVE0

\\.\PHYSICALDRIVE2



wmic:root\cli>

try this command for an amazing amount of information about your diskdrives inside wmic

Code:

path Win32_DiskPartition assoc

or you can code a few lines in the latest leet language c#

or script oldstyle

Code:

ComputerName = "."

Set wmiServices  = GetObject ( _

    "winmgmts:{impersonationLevel=Impersonate}!//" _

    & ComputerName)

' Get physical disk drive

Set wmiDiskDrives =  wmiServices.ExecQuery ( _

    "SELECT Caption, DeviceID FROM Win32_DiskDrive")



For Each wmiDiskDrive In wmiDiskDrives

    WScript.Echo "Disk drive Caption: " _

        & wmiDiskDrive.Caption _ 

        & VbNewLine & "DeviceID: " _

        & " (" & wmiDiskDrive.DeviceID & ")"



    'Use the disk drive device id to

    ' find associated partition

    query = "ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" _

        & wmiDiskDrive.DeviceID & "'} WHERE AssocClass = Win32_DiskDriveToDiskPartition"    

    Set wmiDiskPartitions = wmiServices.ExecQuery(query)



    For Each wmiDiskPartition In wmiDiskPartitions

        'Use partition device id to find logical disk

        Set wmiLogicalDisks = wmiServices.ExecQuery _

            ("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" _

             & wmiDiskPartition.DeviceID & "'} WHERE AssocClass = Win32_LogicalDiskToPartition") 



        For Each wmiLogicalDisk In wmiLogicalDisks

            WScript.Echo "Drive letter associated" _

                & " with disk drive = " _ 

                & wmiDiskDrive.Caption _

                & wmiDiskDrive.DeviceID _

                & VbNewLine & " Partition = " _

                & wmiDiskPartition.DeviceID _

                & VbNewLine & " is " _

                & wmiLogicalDisk.DeviceID

        Next      

    Next

Next

...detect which drive letter is associated with a logical disk partition? Start with the Win32_DiskDrive class and query for instances of Win32_DiskPartition using the DeviceID property and the Win32_DiskDriveToDiskPartition association class. Now you have a collection of the partitions on the physical drive.
Query for the Win32_LogicalDisk that represents the partition using the Win32_DiskPartition.DeviceID property and Win32_LogicalDiskToPartition association class.
Get the drive letter from the Win32_LogicalDisk.DeviceID.
