I just did and got it to work here.
dd if=/dev/hda1 bs=1024 count=1024 |bzip >windows.img
I noticed that dd of a 3.5 gig partition was gonna take a very long time.
The output of my little test confirmed equal in and out counts but there
was no output messages from bzip2; I suppose that's normal behavior for
that program. The bzip2 man page mentions a -c option for standard input
and output but not sure when that is actually needed. Perhaps so if a
filename is specified but you want the output to go to stdout. I did my
tests without the option.
