Initializes the specified disk and disk partition table using the information in the CREATE_DISK structure.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl( (HANDLE) hDevice,              // handle to device
                      IOCTL_DISK_CREATE_DISK,        // dwIoControlCode(LPVOID) lpInBuffer,           // input buffer
                      (DWORD) nInBufferSize,         // size of input buffer
                      (LPVOID) NULL,                 // lpOutBuffer(DWORD) 0,                     // nOutBufferSize(LPDWORD) lpBytesReturned,     // number of bytes returned
                      (LPOVERLAPPED) lpOverlapped ); // OVERLAPPED structure

Status Block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.

Otherwise, Status to the appropriate error condition as a NTSTATUS code.

For more information, see NTSTATUS Values.


When specifying a GUID partition table (GPT) as the PARTITION_STYLE of the CREATE_DISK structure, an application should wait for the MSR partition arrival before sending the IOCTL_DISK_SET_DRIVE_LAYOUT_EX control code. For more information about device notification, see RegisterDeviceNotification.
