[dd] show progress?

[Brett Alton]

I would like to discuss the addition of some sort of progress bar in dd.

When I'm low-level formatting hard drives with:

dd if=/dev/urandom of=/dev/sda bs=10M conv=notrunc

It'd be nice to know the progress of the operation. The same goes for
cloning hard drives.

Is it possible for dd to know the size of the hard drive and calculate
its progress?
