Prodatron released a new utility for his Amstrad CPC operating system SymbOS. With this utility, which can be used in the SymShell, you can easily remove or add the 128 byte AMSDOS header from / to a file. This tool also supports wildcards, so you can add a header to e.g. all files in a directory. For more information on how to use it and to download it go to the CPC Wiki forums.
