I just ran across this in my RSS Reader today  I ve got a cleaner solution for you  This example is in Delphi  but can very easily be converted to C C    It s all Win32    Query all value names from the following registry location   HKLM SYSTEM MountedDevices  One by one  pass them into the following function and you will be returned the device name  Pretty clean and simple  I found this code on a blog here   function VolumeNameToDeviceName const VolName  String   String  var   s  String    TargetPath  Array 0  MAX PATH  of WideChar    bSucceeded  Boolean  begin   Result              VolumeName has a format like this      Volume c4ee0265-bada-11dd-9cd5-806e6f6e6963        We need to strip this to Volume c4ee0265-bada-11dd-9cd5-806e6f6e6963    s     Copy VolName  5  Length VolName  - 5      bSucceeded    QueryDosDeviceW PWideChar WideString s    TargetPath  MAX PATH   lt  gt  0    if bSucceeded then   begin     Result    TargetPath    end   else begin        raise exception   end   end

GetLogicalDrives   enumerates all mounted disk partitions  not physical drives   You can enumerate the drive letters with  or without  GetLogicalDrives  then call QueryDosDevice   to find out which physical drive the letter is mapped to   Alternatively  you can decode the information in the registry at HKEY LOCAL MACHINE SYSTEM MountedDevices   The binary data encodings there are not obvious  however   If you have a copy of Russinovich and Solomon s book Microsoft Windows Internals  this registry hive is discussed in Chapter 10

One way to do it    Enumerate logical drives using GetLogicalDrives For each logical drive  open a file named      X    without the quotes  where X is the logical drive letter  Call DeviceIoControl passing the handle to the file opened in the previous step  and the dwIoControlCode parameter set to IOCTL VOLUME GET VOLUME DISK EXTENTS   HANDLE hHandle  VOLUME DISK EXTENTS diskExtents  DWORD dwSize         iRes   DeviceIoControl      hHandle      IOCTL VOLUME GET VOLUME DISK EXTENTS      NULL      0       LPVOID   amp diskExtents       DWORD  sizeof diskExtents        LPDWORD   amp dwSize      NULL      This returns information of the physical location of a logical volume  as a VOLUME DISK EXTENTS structure   In the simple case where the volume resides on a single physical drive  the physical drive number is available in diskExtents Extents 0  DiskNumber

Might want to include the old A  and B  drives as you never know who might be using them  I got tired of USB drives bumping my two SDHC drives that are just for Readyboost  I had been assigning them to High letters Z  Y  with a utility that will assign drive letters to devices as you wish   I wondered      Can I make a Readyboost drive letter A    YES  Can I put my second SDHC drive letter as B    YES   I ve used Floppy Drives back in the day  never thought that A  or B  would come in handy for Readyboost     My point is  don t assume A   amp  B  will not be used by anyone for anything You might even find the old SUBST command being used

I ve modified an open-source program called  dskwipe  in order to pull this disk information out of it  Dskwipe is written in C  and you can pull this function out of it  The binary and source are available here  dskwipe 0 3 has been released  The returned information will look something like this   Device Name                         Size Type      Partition Type ------------------------------ --------- --------- --------------------     PhysicalDrive0               40 0 GB Fixed     PhysicalDrive1               80 0 GB Fixed  Device Harddisk0 Partition0     40 0 GB Fixed  Device Harddisk0 Partition1     40 0 GB Fixed     NTFS  Device Harddisk1 Partition0     80 0 GB Fixed  Device Harddisk1 Partition1     80 0 GB Fixed     NTFS     C                            80 0 GB Fixed     NTFS     D                             2 1 GB Fixed     FAT32     E                            40 0 GB Fixed     NTFS

Make a list of all letters in the US English Alphabet  skipping a  amp  b   CDEFGHIJKLMNOPQRSTUVWXYZ   Open each of those drives with CreateFile e g  CreateFile      C     If it does not return INVALID HANDLE VALUE then you got a  good  drive  Next take that handle and run it through DeviceIoControl to get the Disk    See my related answer for more details

The answer is far simpler than all the above answers  The physical drive list is actually stored in a Registry key which also gives the device mapping   HKEY LOCAL MACHINE SYSTEM CurrentControlSet Services disk Enum  Count is the number of PhysicalDrive  and each numbered Registry Value is the corresponding physical drive   For example  Registry Value  0  is PhysicalDrive0  The value is the actual device PhysicalDrive0 is mapped to  The value contained here can be passed into CM Locate DevNode within parameter pDeviceID to use the plug and play services  This will allow you to gather a wealth of information on the device  Such as the properties from Device Manager like  Friendly Display Name  if you need a name for the drive  serial numbers and more   There is no need for WMI services which may not be running on the system or other hackery and this functionality has been present in Windows since at least 2000 and continues to be the case in Windows 10

The only sure shot way to do this is to call CreateFile   on all     Physicaldiskx where x is from 0 to 15  16 is maximum number of disks allowed   Check the returned handle value  If invalid check GetLastError   for ERROR FILE NOT FOUND  If it returns anything else then the disk exists but you cannot access it for some reason

This might be 5 years too late     But as I see no answer for this yet  adding this   We can use Setup APIs to get the list of disks ie   devices in the system implementing GUID DEVINTERFACE DISK    Once we have their device paths  we can issue IOCTL STORAGE GET DEVICE NUMBER to construct      PHYSICALDRIVE d  with STORAGE DEVICE NUMBER DeviceNumber  See also SetupDiGetClassDevs function   include  lt Windows h gt   include  lt Setupapi h gt   include  lt Ntddstor h gt    pragma comment  lib   setupapi lib      include  lt iostream gt   include  lt string gt  using namespace std    define START ERROR CHK                   DWORD error   ERROR SUCCESS           DWORD failedLine                      string failedApi    define CHK  expr  api                    if      expr                              error   GetLastError                  failedLine     LINE                   failedApi     api                     goto Error Exit                       define END ERROR CHK                     error   ERROR SUCCESS                 Error Exit                            if   ERROR SUCCESS    error               cout  lt  lt  failedApi  lt  lt    failed at    lt  lt  failedLine  lt  lt      Error Code -

I just ran across this in my RSS Reader today  I ve got a cleaner solution for you  This example is in Delphi  but can very easily be converted to C C    It s all Win32    Query all value names from the following registry location   HKLM SYSTEM MountedDevices  One by one  pass them into the following function and you will be returned the device name  Pretty clean and simple  I found this code on a blog here   function VolumeNameToDeviceName const VolName  String   String  var   s  String    TargetPath  Array 0  MAX PATH  of WideChar    bSucceeded  Boolean  begin   Result              VolumeName has a format like this      Volume c4ee0265-bada-11dd-9cd5-806e6f6e6963        We need to strip this to Volume c4ee0265-bada-11dd-9cd5-806e6f6e6963    s     Copy VolName  5  Length VolName  - 5      bSucceeded    QueryDosDeviceW PWideChar WideString s    TargetPath  MAX PATH   lt  gt  0    if bSucceeded then   begin     Result    TargetPath    end   else begin        raise exception   end   end

WMIC  wmic is a very complete tool  wmic diskdrive list   provide a  too much  detailed list  for instance  for less info   wmic diskdrive list brief    C  Sebastian Godelet mentions in the comments      In C    system  wmic diskdrive list      As commented  you can also call the WinAPI  but    as shown in  How to obtain data from WMI using a C Application    this is quite complex  and generally done with C    not C    PowerShell  Or with PowerShell   Get-WmiObject Win32 DiskDrive

Make a list of all letters in the US English Alphabet  skipping a  amp  b   CDEFGHIJKLMNOPQRSTUVWXYZ   Open each of those drives with CreateFile e g  CreateFile      C     If it does not return INVALID HANDLE VALUE then you got a  good  drive  Next take that handle and run it through DeviceIoControl to get the Disk    See my related answer for more details

One way to do it    Enumerate logical drives using GetLogicalDrives For each logical drive  open a file named      X    without the quotes  where X is the logical drive letter  Call DeviceIoControl passing the handle to the file opened in the previous step  and the dwIoControlCode parameter set to IOCTL VOLUME GET VOLUME DISK EXTENTS   HANDLE hHandle  VOLUME DISK EXTENTS diskExtents  DWORD dwSize         iRes   DeviceIoControl      hHandle      IOCTL VOLUME GET VOLUME DISK EXTENTS      NULL      0       LPVOID   amp diskExtents       DWORD  sizeof diskExtents        LPDWORD   amp dwSize      NULL      This returns information of the physical location of a logical volume  as a VOLUME DISK EXTENTS structure   In the simple case where the volume resides on a single physical drive  the physical drive number is available in diskExtents Extents 0  DiskNumber
