IOCTL_DISK_DELETE_DRIVE_LAYOUT IOCTL

Removes the boot signature from the master boot record, so that the disk will be formatted from sector zero to the end of the disk. Partition information is no longer stored in sector zero.

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

C++
BOOL DeviceIoControl(
  (HANDLE) hDevice,               // handle to device
  IOCTL_DISK_DELETE_DRIVE_LAYOUT, // dwIoControlCodeNULL,                           // lpInBuffer0,                              // nInBufferSizeNULL,                           // lpOutBuffer0,                              // nOutBufferSize(LPDWORD) lpBytesReturned,      // number of bytes returned
  (LPOVERLAPPED) lpOverlapped     // OVERLAPPED structure
);
