Why use block writes of 1MB ? It may be wiser to leave this
to default 512 bytes to avoid any null padding errors. If the bs=bytes option is given, and no conversion other than
sync, noerror, or notrunc is specified, it writes the data read (which could be smaller than what was requested) in a separate output block. If this output block has precisely the same length as was read, fine, otherwise, the data is padded with NULs (see man dd for details).
If you do not specify one then no conversion will be done, no default padding null/spaces will be done, may I think you need little home work.
Just a point of view ...
very useful note, may be some one will benefit from this.
