So DDrescue is done. Here is what is shows :

Code:
xyz@xyz:~$ sudo ddrescue -f -r3 /dev/sdh /dev/sda mapfile
GNU ddrescue 1.23
Press Ctrl-C to interrupt
     ipos:    1264 GB, non-trimmed:        0 B,  current rate:       0 B/s
     opos:    1264 GB, non-scraped:        0 B,  average rate:   7822 kB/s
non-tried:        0 B,  bad-sector:    2821 MB,    error rate:  19091 kB/s
  rescued:    1997 GB,   bad areas:      794,        run time:  2d 22h 56m
pct rescued:   99.85%, read errors: 22087375,  remaining time:         n/a
                              time since last successful read:      5m  1s
Finished               


What is the next step ? Must Itry to recover somehow the ~3GB missing or is it useless ? Must I now focus on the copy of my HDD ?

Thank you again for your help !

Now you can try to recover data from the captured image and see if you are satisfied with the result.
If the gaps lie in the most important data, it may try to complete the reading using the log made in DD.

I am using testdisk to try to recover a partition on the clone I made.

I am a bit lost on what to do. Here is what I did so far :
- select the drive with the clone (ok)
- select the partition table type (Intel) (ok)
- analyse -> tells me "Bad relative sector"
- Quick search

Testdisk find a NTFS partition :

Code:
Disk /dev/sda - 8001 GB / 7452 GiB - CHS 972801 255 63
     Partition               Start        End    Size in sectors
>* HPFS - NTFS              0  32 33 243201  45 44 3907024896


If I ask to list the fils (p), testdisk tells me "Can't open filesystem. Filesystem seems damaged".

What seems weird is that the partition that existed on the drive was not bootable. Should I change it to primary ?

What should I do now ?

Sorry for my lack of knowledge here. And thank you so much for your help.

Try DMDE.
In demo you can recovery to 4000 files from one directory without size limit.
DMDE also show if any problem with partition and file system.

DMDE finds many files indeed, but with no original names or path whatsoever. I feel almost all my data are untouched, but only the partition table is broken and make the disk unreadable (it is but a guess and it may be silly :? )

Is there no way to try to recover the partition and the whole hierarchy ?

Sorry if it is a dumb question :roll:

Can you show the main partitioning window after selecting the disk?

DMDE found partitions and managed to show me some hierarchy.

However, if I want to restore my files, I can't do it 4000 at a time :shock:

Do you have any suggestion to it more efficiently ?

Thanks again !

R-Studio finds more files than DMDE, but again, it's highly limited for restoration in its free version :(

You have a budget problem not a data recovery one. DMDE is 20 USD for a 30 day license. There's no such thing as a free lunch, you either pay with your wallet or you pay with your time.
