I assume that is the cause. On magnetic media, it probably isn't an issue. Whenever the cache can hold an appreciable percentage of the destination device, it might be.

This reply is to Clarence-Adams. (I know, I should have quoted.)

That's ... expected, if you think about it.

I just tried it as you are running it, with two different ttys. Ctrl-Alt-F2 is running dd and I logged in on Ctrl-Alt-F3 and issued the kill command. The output is on Ctrl-Alt-F2, where dd is running.

My example failed because I backgrounded dd and did it all from one terminal.

Thanks jamesf, I got it. I guess it's complete whenever it says (40.0 GB) copied. Thanks for your help everybody.
