Hi all,
First of all, I want to thank Elmar for making hfsprescue open source.
For the sake of completeness, I will describe briefly my problem regarding the internal HDD corruption. I have a MacBook Pro (early 2011) which is unable to boot from the internal HDD called Macintosh HD. I believe that the internal HDD is not physically damaged. The problem started when I upgraded from last version of Sierra to High Sierra, which failed. And, since I'm totally idiot and I haven't backed up most of the files, I have lost 3 years of work. Now, when using First Aid on Macintosh HD through Disk Utility, an error regarding uncountably many missing thread records appears, so as I understand the problem is in the catalog file data (there's nothing pointing to the parent folder due to the incorrect number of thread records). I'm currently booting from an external HDD with Sierra installed on it. As expected, I can't mount Macintosh HD.
My volumes are the following:
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_CoreStorage Macintosh HD 499.2 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1 (internal, virtual):

Logical Volume on disk0s2

Unencrypted
/dev/disk2 (external, physical):

0: GUID_partition_scheme *999.5 GB disk2
1: EFI EFI 209.7 MB disk2s1
2: Apple_HFS Untitled 998.6 GB disk2s2
3: Apple_Boot Recovery HD 650.0 MB disk2s3
/dev/disk3 (external, physical):

Unfortunately, when applying sudo ./hfsprescue -s1 diskname for both the logical volume and the physical volume, I always get stuck at 0.17%. Interestingly, after one day running, some megabytes changed, but the percentage remained the same.
Here follows what I see on the shell:
sudo ./hfsprescue -s1 /dev/disk1

I tried disabling everything from sleeping as it was suggested in other threads, but the percentage still at 0.17%.
Thanks in advance.
P.S. : Interestingly, I can't kill hfsprescue process unless I use kill -9 PID. As I understand this information is probably not relevant, though.
