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).
Just a point of view ...

These are programs executed with superuser permissions invoked
by call to function setuid() ... a potential security hazard.
To know which all programs on your system are set suid, do:
'find / -user root -mount -perm -4000 print'
