Would 'pv' help?
dd if=/dev/zero | pv | of=/dev/null
Apparently if you know the approximate 'size' it will give you will an
ETA.
dd if=/dev/sdb | pv -s 2G | dd of=DriveCopy1.dd bs=4096
It can also be used directly as in the man page example
pv file | nc -w 1 somewhere.com 3000
In this latter case it evaluates the file size directly.
