DD is not working

[Scott Ehrlich]

Also check /var/log/messages and see if it gives any indication of what 
might be going on.

If the drive is mounted, and you do a df, the left column shows the /dev 
device the system is using.   Verify that, then as root umount the volume 
(far right column), then, either as root or yourself, dd 
if=/dev/whatever_it_said of=blah

This is provided you have proper disk space and proper permissions to 
write to the volume you want to save the data to.
