Yes, that's very good and has only got better since I last used it. It reads through the disk once, copying what read OK and making a note of the sectors that failed, then it goes back to tackle them with various strategies, e.g. approaching from one direction then the other. Needs a bit of study to understand the options. That's GNU's ddrescue(1) we're talking about; package gddrescue on Ubuntu. http://www.gnu.org/software/ddrescue/ The package ddrescue, no `g', is also on old Ubuntus, e.g. 12.04LTS, is a variant I've no experience of that contains the dd_rescue(1) command. It has been dropped in later Ubuntus.
