What are you expecting the output to be ?

The dd is doing what you told it to.

A couple of things are at play in your case. 1) You did not specify a cbs (conversion buffer size) so the default size was used. This results in padding being added to the output. 2) cat is a lousy tool to use when non-ASCII data is being displayed.

Use od (or xd) to examine your output file.

e.g.

xd -Ad -v -txC myfile

which will display the hexadecimal equivalent for each byte.

Man dd and xd for details.
