Try, for example
$ dd_rescue /dev/sda1 - | gzip > image.gz
Where /dev/sda1 is your dying disk and image.gz is the compressed output.
Be aware that having stdout as the destination for dd_rescue means
it is unable to handle writing sparse files properly (if that is required).
from what I read, sparse files is the empty blocks/spaces. I only need the real data to be as it were. Thanks for the tip. I'll try this one out though I'm wondering if logging still works by doing it like this
$ dd_rescue -v /dev/sda1 -l sda.log - | gzip > image.gz
cheers,
Owen.
