WHAT:
Change the ddrescue output format when using the fillmode-with-location
option, i.e.,
ddrescue --fill-mode=l- fillfile imagefile mapfile
from the multiline-per-sector:

Thanks. This sounds interesting. I'll see how it can be implemented.
Thanks Antonio for the feedback. This was my main observation on

Hello,
I use ddrescue exclusively from the System Rescue CD environment. The
latest System Rescue CD build of 2018-04-02 (see
http://www.system-rescue-cd.org/Download/) still uses ddrescue-1.21-r1
(see http://www.system-rescue-cd.org/Detailed-packages-list/), even

I have a ddrescue-generated "fulldrive.img" file of a complete 1 TB
drive comprising 4 partitions - C: (200 GB Win7 OS) G:(800 GB Data) (and
2 other recovery/OEM partitions that are not important for this discussion).
I have a current system with a new 2 TB drive installed with the same 4
suitable tool for the job might be something like partclone, or
clonezilla (which is built on top of partclone). Also, take a look at
combining partclone's --domain option with ddrescue's --domain-mapfile
option.

While I discovered ddrescue when I really needed to rescue a disk (for
which mapfile is of course critical), I now routinely use it to create
periodic full backups of my hard drive as (mountable) image files, as I
find it superior for that purpose than the various other disk cloning

would certainly have been educational, but was hoping not to
have to do. So I'll download the update and make a new CD from that.
Thanks again!

Thanks David, your response, as well as Timothy's response to my
question as to why use the NTFS tools for a partition-based copy, allude
to the difference between a partition-based clone (sector by sector

Hi António,
I guess that by "Linux" you mean "a given distribution".
Or I suppose I meant "a given repository," which then affects all
distributions that use that repository ... though as I mentioned I'm
still trying to figure out the correlation between those two. :-)

Didn't see a response to the list to your question from a couple of
weeks ago. Perhaps someone replied privately; if not, the ddrescue
manual includes this paragraph:

Perhaps related to Robert's comment, but the ddrescue man page says:
The format for running ddrescue is:

so your specifying --force at the end rather than at the beginning as
indicated (quite aside from the redundancy) may be throwing off the
