IOCTL_DISK_DELETE_DRIVE_LAYOUT IOCTL

-description

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.

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

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

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