Ddrescue will exit when it is done doing what you told it to do,
considering all the options you provided it. The only thing the domain
file does is cause ddresuce to only make attempts at the areas
specified in the domain file (in this case the used portion of the
partition). So when it is done trying the area specified in the domain
file (again, considering all the other options provided to ddrescue),
it will exit on its own. So to clarify, when using a domain file and
ddrescue exits normally, ddrescue is done with its attempt at
recovering that area with the options you provided. If you stop
providing the domain file, then ddrescue will continue its attempts on
the entire disk (partition in your case). You can actually go back to
using a domain file at any time and ddresuce will again only make
attempts the area specified. I will let someone else discuss the
options you are using, and what would be next.
Thanks for the great explanation ;)
Now for my question: I am curious, were any/many errors reported when
you ran ddru_ntfsbitmap? If you did not delete it, then
"ntfsbitmap_rescue_report.log" would have this information. Not that
it matters that much, as any errors or unread parts of the extracted
bitmap file will be filled with FF to ensure there will not be any
missed areas.
Here's the ntfsbitmap_rescue_report.log - I guess everything is OK :
__bootsec.log

Keep an eye out for the next release of ddrutility, which hopefully
will be sometime this weekend. I am adding an option to
ddru_ntfsbitmap that will allow creation of a second domain file that
will be just for the MFT. This would allow someone to attempt recovery
of the MFT first, and also see the errors of just the MFT, which could
help with some decisions about how to proceed with the recovery.
Will do, that will be a great feature \o/
Greetings,
Andrej.
