Hello,
before my questions starts: Thanks a lot for this great tool! :-)
I have trouble to restore some files from a SSD. Maybe i can find here some help. This is some information I have about the state of the drive.
$ sudo diskutil verifyVolume "/Volumes/OWC Aura SSD"
...
Checking catalog file
Invalid node structure
The volume OWC Aura SSD could not be verified completely
File system check exit code is 8
Restoring the original state found as mounted
Problem -69842 occurred while restoring the original mount state
Error: -69845: File system verify or repair failed
Underlying error: 8: Exec format error
I try to get some files from the drive restored, but the MacOS tool, as well as some others failed up to now.
This looks good:
$ sudo ./hfsprescue_x64 -s1 /dev/sdb2 -b 512

Done.
and also sudo ./hfsprescue_x64 -s2
worked well
but when I check the file catalog, the entries look not so promising.
$ sudo ./hfsprescue_x64 --list | grep IMG

The entries have _F_INVALID_START_BLOCK_ and/or the file size is incorrect.
Consequently when I try to restore single files, I get an error message File xyz not restored.
or a file is created but the content is not correct.
What can I do at this point?
Best Regards and thanks again for this tool.
