The file backup.img is created on someremotehost, but it has zero length. The
drive hda does not spin up on the laptop when I issue this command.

dd if=/dev/hda | ssh mark@192.168.25.125 ">/home/mark/backup.img"

I get the message after I enter my password - "Warning: no xauth data; using
fake authentication data for X11 forwarding."

However, if I do cfdisk /dev/hda from the same knoppix terminal window, the
drive hda does spin up and cfdisk reports the correct partitions.

What am I missing to get the drive copied?

Thanks!
