Topic: Format Partition to NTFS c++
I am an undergrad student developing a senior design project which encompasses the need to partition and format a hard disk drive. I am developing this in the c++ language and I have been stumped on formatting the partition. Maybe my source code to partition is done so incorrectly? I come to the GParted forums in hopes of assistance from experienced individuals.
The following is the source code that has been developed to partition an external HDD:
//-------------------INITIALIZE AND PARTITION HDD-------------------------------//
#include "stdafx.h" //
#include <Windows.h> //
#include <stdio.h> //
#include <iostream> //
#include <tchar.h> //
#include <winioctl.h> //
#include <shellapi.h> //
//-------------------------------------Main-------------------------------------//
int main() //
{ //
//char *dsk = "\\\\.\\PhysicalDrive1"; //
HANDLE hDisk; //
DWORD junk = 0; //
BOOL bResult = false; //
//
hDisk = CreateFile(TEXT("\\\\.\\PhysicalDrive1"), //
GENERIC_READ | GENERIC_WRITE, //
FILE_SHARE_READ | FILE_SHARE_WRITE, //
NULL, //
OPEN_EXISTING, //
0, //
NULL); //
//
//error handler for driver //
if (hDisk == INVALID_HANDLE_VALUE) //
{ //
CloseHandle(hDisk); //
return 1; //
} //
//
//
CREATE_DISK dsk; //
dsk.PartitionStyle = PARTITION_STYLE_MBR; //
dsk.Mbr.Signature = 9999; //
//
//-------------------------------Initialize Disk--------------------------------//
bResult = DeviceIoControl(hDisk, //initialize raw disk //
IOCTL_DISK_CREATE_DISK, //
&dsk, sizeof(dsk), //
NULL, 0, //
&junk, //
NULL); //
//
if (!bResult) //
{ //
return GetLastError(); //
} //
//
bResult = DeviceIoControl(hDisk, //to flush changes //
IOCTL_DISK_UPDATE_PROPERTIES, //
NULL, 0, NULL, 0, &junk, NULL); //
//
if (!bResult) //
{ //
return GetLastError(); //
} //
//
//
//----------------------------Partition Disk--------------------------------//
LARGE_INTEGER lgPartSize; //
//
lgPartSize.QuadPart = (1024 * 1024 * 1024); //
//
DWORD dwDriverLayoutInfoExLen = sizeof(DRIVE_LAYOUT_INFORMATION_EX) + 3 * //
sizeof(PARTITION_INFORMATION_EX); //
//
DRIVE_LAYOUT_INFORMATION_EX *pdg = (DRIVE_LAYOUT_INFORMATION_EX *)new //
BYTE[dwDriverLayoutInfoExLen]; //
//
if (pdg == NULL) //
{ //
return -1; //
} //
//
SecureZeroMemory(pdg, dwDriverLayoutInfoExLen); //
//
pdg->PartitionStyle = PARTITION_STYLE_MBR; //
pdg->PartitionCount = 1; //
pdg->Mbr.Signature = 99999; //
//
pdg->PartitionEntry[0].PartitionStyle = PARTITION_STYLE_MBR; //
pdg->PartitionEntry[0].StartingOffset.QuadPart = 3225 //
pdg->PartitionEntry[0].PartitionLength.QuadPart = lgPartSize.QuadPart * 40; // <-- partition size in GB
pdg->PartitionEntry[0].PartitionNumber = 1; //
pdg->PartitionEntry[0].RewritePartition = TRUE; //
pdg->PartitionEntry[0].Mbr.PartitionType = PARTITION_NTFT; //
pdg->PartitionEntry[0].Mbr.BootIndicator = TRUE; //
pdg->PartitionEntry[0].Mbr.RecognizedPartition = 1; //
pdg->PartitionEntry[0].Mbr.HiddenSectors = 32256 / 512; //
//
bResult = DeviceIoControl(hDisk, //device to be queried //
IOCTL_DISK_SET_DRIVE_LAYOUT_EX, //operation to perform //
pdg, sizeof DRIVE_LAYOUT_INFORMATION_EX,//sizeof(pdg), //
NULL, 0, // output buffer //
&junk, //# bytes returned //
NULL); //
//
if (!bResult) //
{ //
return GetLastError(); //
} //
//
//
CloseHandle(hDisk);
return 0; //
} //
//--------------------------------------------------------------------------//After executing the code the partition of size 40GB is examined using Windows Disk Management:
I figured I would be directed to Windows API:
uint32 Format(
[in] string FileSystem = "NTFS",
[in] boolean QuickFormat,
[in] uint32 ClusterSize = 4096,
[in] string Label = "",
[in] boolean EnableCompression = false
);
and
DWORD SHFormatDrive(
_In_ HWND hwnd,
UINT drive,
UINT fmtID,
UINT options
);
but I am not sure how to implement these functions to my existing code. I appreciate any feedback in advanced. Thank you for your time.
