Use rsync instead, if you can.  If sometime in the next
several hours you have a network failure, just issue the
rsync command again and it will pick up where it left off.

E.g...

  rsync -e 'ssh -C -c blowfish' -v user@remote:/dev/hddd hdd.img

or for newer versions, ssh is the default...

  rsync -vz user@remote:/dev/hddd hdd.img
