LPTSTR lpVolumeNameBuffer[100]; LPDWORD lpVolumeSerialNumber; LPDWORD lpMaximumComponentLength; LPDWORD lpFileSystemFlags; LPTSTR lpFileSystemNameBuffer[100]; GetVolumeInformation("C:\\",lpVolumeNameBuffer,100,&lpVolumeSerialNumber, lpMaximumComponentLength,lpFileSystemFlags,lpFileSystemNameBuffer,100 ); use the above function it returns the Volume Serial Number of the physical C drive . Cheers :)

Hmmm. How about:
TCHAR caVolumeNameBuffer[ 100 ]; DWORD dwVolumeSerialNumber = 0; DWORD dwMaximumComponentLength = 0; DWORD dwFileSystemFlags = 0; TCHAR caFileSystemNameBuffer[ 100 ]; GetVolumeInformation( _T( "C:\\" ), caVolumeNameBuffer, 100, &dwVolumeSerialNumber, &dwMaximumComponentLength, &dwFileSystemFlags, caFileSystemNameBuffer, 100 );Your example was not passing in valid pointers, only uninitialized ones. Might want to ensure proper termination of theTCHARbuffers as well. However, I think the OP was asking about the physical device name for the drive, not its serial number; I think they were looking for information such as if a drive is\\.\PhysicalDrive0or\\.\PhysicalDrive1, etc. You need that information to open the device itself (the hard drive itself) to do things like send IOCTLs. I do not think that the function you specified will return that information. Peace! -=- James
If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

If you need that to do something like send IOCTLs (
DeviceIoControl), you can also open the device by using the following syntax:\\.\C:- Open physical device for drive "C"\\.\D:- Open physical device for drive "D"\\.\A:- Open physical device for drive "A" I do not know all of the cases where that format and the\\.\PhysicalDrive_**x**_format are interchangable, but I know you can use it when getting aHANDLEto use withDeviceIoControl. Also, not that you are likely to hit it, but there is a bug in older versions of theWin32_DiskDriveWMI class that limits the number of drives returned. The above method should also work on Windows NT 4.0 versions prior to SP4, but the WMI method will not. Peace! -=- James

DeleteFXPFiles & CheckFavorites (Please rate this post!)Thanks a lot! I just need to use \\.\PhysicalDrivex to open the disk contains the appointed logical volumn. I've lookup in MSDN and found the method. Use DeviceIoControl and send IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS. But MSDN says it can only use in win2000 and later version.
