I tried dd on files to replace the first 512 bytes of a file , but

When the target is a file, you need to include "conv=notrunc" so
that the file will not be truncated to zero length when it is
opened. That is not an issue when the target is a block device,
but there is no harm in using "conv=notrunc" there, too.
