After some more looking I found that dd_rescue is not the same as
ddrecscue! dd_rescue and rhelp and the older brother of the new
ddrescure (all new code).
So what I am now doing from the live cd.
sudo aptitude install sshfs
sudo adduser ubuntu fuse
sudo mkdir mnt/remote
sudo sshfs -o idmap=user douglas4 at 192.168.2.100/:download /mnt/remote
#you get the address with ficonfig!
sudo ddrescue /dev/sda /mnt/remote/HDfile /mnt/remote/HDlog
And now it is happily working away. I wonder how long this 40gb drive will take?
After that I will make a duplicate backup on the remote computer and
work on the backup to see what I can extract, likely with that
photoextract program. ?
Thanks all and hope this little log helps someone. Finding all the
answers in one place was not possible. Will post more as it goes. Hope
to hear from anyone with more ideas or help!
