How to partition physical disk?

[bluestar]

Dear Sir:

I use below steps to create new logical disk, but something
wrong.

(1)use DeviceIoControl:IOCTL_DISK_GET_DRIVE_GEOMETRY to
get physical disk size and Bytes per Sector in disk.

(2)use DeviceIoControl:IOCTL_DISK_CREATE_DISK、
DeviceIoControl:IOCTL_DISK_UPDATE_PROPERTIES、
DeviceIoControl:IOCTL_DISK_SET_DRIVE_LAYOUT_EX to
partition disk.( below code )

(3) after partitioning, use "format.com" in WinXP to
format disk.

But I found the step for partition can fail. I can't
use NTFS format to parition and if I use FAT32 format
to do, it would happen wrong partition disk to reboot
pc. For example, in one physical disk:30G, after
partitioning, it will shows 3 parts(27.5G,2G,27.G)
and no logical drivers created.

Could anyone tell me what's wrong with my code and
how to modify it? And How to improve the speed of
format?

:
You cuold use DISKPART utility (at least, on Win2003 - not sure about XP) -
to create partitions, for example.

Dear Boris:

I can't use other tools to create partition and format.
I need to both procedures in my code.

I also try to use below code to format, and it failed when
running command FormatEx.

What's wrong with this code?

//---------------------------------------------------------------------------------------//

TCHAR strWinSysDir[MAX_PATH],szDest[MAX_PATH];
HMODULE hK32lib;
PWCHAR Label = L"";
PWCHAR Format = L"FAT32";
BOOL bResult = TRUE;

GetSystemDirectory(strWinSysDir,MAX_PATH);//get c:\Windows\System32

_tcscpy_s (szDest,MAX_PATH,strWinSysDir);
_tcscat_s(szDest, MAX_PATH, _T("\\fmifs.dll"));

hK32lib = LoadLibrary( szDest );

if( !(FormatEx = (PFORMATEX)
GetProcAddress( GetModuleHandle( "fmifs.dll"),"FormatEx" )) ) {
return FALSE;
}

FormatEx((PWCHAR)cDrive, FMIFS_HARDDISK, Format, Label, TRUE,
512, FormatExCallback);

FreeLibrary(hK32lib);

BOOLEAN __stdcall FormatExCallback( CALLBACKCOMMAND Command, DWORD
Modifier, PVOID Argument )
{
PDWORD percent;
PTEXTOUTPUT output;
PBOOLEAN status;

switch( Command ) {

case PROGRESS:
percent = (PDWORD) Argument;
//_tprintf(L"%d percent completed.\r", *percent);
break;

case OUTPUT:
output = (PTEXTOUTPUT) Argument;
//fprintf(stdout, "%s", output->Output);
break;

case DONE:
status = (PBOOLEAN) Argument;
if( *status == FALSE ) {
//_tprintf(L"FormatEx was unable to complete successfully.\n\n");
}
break;
}
return TRUE;
}

//---------------------------------------------------------------------------------------//

I found the failed probability of partition and format is 5%
When failed to partition, the PC would crash and reboot.
The minidump file records the ftdisk.sys happens error.

I tried to modify code to do(below code),
but I don't know where is wrong.

Does anyone help me????
