Here is my sample code:

PATA_PASS_THROUGH_DIRECT pATAPTD = NULL;
DWORD dataSize = sizeof(ATA_PASS_THROUGH_DIRECT) + 512;
pATAPTD = (PATA_PASS_THROUGH_DIRECT) VirtualAlloc(NULL, dataSize, MEM_COMMIT, PAGE_READWRITE);
ZeroMemory(pATAPTD, dataSize); 
pATAPTD->Length = sizeof(ATA_PASS_THROUGH_DIRECT); 
pATAPTD->DataBuffer = (PVOID)((char*)pATAPTD + sizeof(ATA_PASS_THROUGH_DIRECT));
pATAPTD->DataTransferLength = 512; 
pATAPTD->TimeOutValue =  25;
pATAPTD->AtaFlags = 25;

unsigned short* pPassWrdBuffer = NULL;
pPassWrdBuffer = new unsigned short[256];
memset(pPassWrdBuffer,0,512);
pPassWrdBuffer[1]= Password;

char *pDataPtr = (char *)((char *)pATAPTD + sizeof(ATA_PASS_THROUGH_DIRECT));

memcpy_s((void *)( pDataPtr ), 512,
pPassWrdBuffer, 512);

pATAPTD->CurrentTaskFile[1] = 0x01;
pATAPTD->CurrentTaskFile[6] = 0xF1;

bResult = DeviceIoControl(m_hDisk, 
            IOCTL_ATA_PASS_THROUGH_DIRECT, 
            pATAPTD, 
            dataSize,/* input buffer and size */ 
            pATAPTD,
            dataSize,/* output buffer and size */ 
            &BytesCopied,/* bytes copied to output buffer*/ 
            NULL/* no overlapping */  
            );

This call fails only on windows 8 and windows server 2012 throwing message "The parameter is incorrect" (@err = 87). It works fine on windows 7. Can anyone provide some solution to this issue?

    Are you using two differently configured machines to test this, or are you carefully ensuring that the operating system is the *only* variable that is changing? Take note of the restrictions listed at the top of [the documentation](http://msdn.microsoft.com/en-us/library/windows/hardware/ff559315.aspx). – Cody Gray - on strike Mar 12 '13 at 11:12
  • Operating system is the only thing changing here. Hardware remains the same. – Manvendra Kumar Mar 13 '13 at 04:29
