<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks for the note. I found the following online which shows how to run dd with time to get the time used when done and also shows how to check on the progress.<br>
<br>
time dd if=/dev/urandom of=/dev/sdb<br>
<br>
Checking on progress<br>
<br>
The dd command doesn’t give us any useful feedback whilst it’s running, but we can force it to cough up some useful data by prodding it with a USR1 signal. Assuming you only have one instance of dd running we can use:<br>
<br>
kill -USR1 `pidof dd`<br>
<br>
(Note, they are backticks around the pidof dd command.)<br>
