File (re-writing a portion) ????

I have a file "XXXXXXXXXXXXXXDDD" and I want to change the "DDD" to "SSS"... The file size will always be different. It is not text.

I've tried open ... binary and random.. etc etc.. Nothing works.Both "SSS" and "DDD" are the last 128 characters of the file. The files range in size from 3-6 megs so I don't want to re-write the entire file, but simply overwrite the small portion.
