I really would like to know what is the different between "dd" and "cp" in the context of diskcopy, and specifically to making a boot disk. Any taker ? :-)
I think that `cp' decides its own buffering, while `dd' let you decides how buffering is exactly done. But since the system already guarantees that a diskette receives full sectors (`dd' is more meaningful for magnetic tapes), and moreover, seems to buffer the writes through memory anyway, deciding the size of the chunks sent to the system is pretty meaningless for non-tapes, so far that I understand things. Some people might argue that there is some speed consideration into writing one diskette cylinder per write, which would be true (even if not very significant) if the system was directly writing to the diskette, but the intent is rather defeated and even improved by the system buffering, anyway. But I'm no specialist.
