PR7.0 keeps stucks always at the same region, no matter what

#1 Post by helt »

I tried almost every possibility of options. Paranoid yes/no, bruteforce yes/no. But the result is always the same:

photorec makes good progress until sector 529.something, then it appears to keep looping over and over again over the same sectors. As you can see, the current sector sometimes even decreases.

However, this is just 25% of the whole volume-set. And i am really passionate to somehow get the other 75% recovered, too. I am trying to recover the data for more than one month now, but never got past the 25%.

Any ideas anyone?

Please try PhotoRec 7.1-WIP. Copy the photorec.ses file from 7.0, start PhotoRec 7.1-WIP and choose to continue the previous session.

is there a static binary avaliable? I am running PR on a NAS and have not really a clue about compiling Linux source code.

Code: Select all

Linux DiskStation 3.10.35 #5644 SMP Fri Jan 22 13:38:47 CST 2016 x86_64 GNU/Linux synology_cedarview_412+

ok. the static from the 7.1-WIP does start. If it starts, the rest will work as expected, too, right?

ok. seems to work now.

Code: Select all

Pass 1 - Reading sector 5529628568/19515727872, 521217 files found
Elapsed time 0h39m12s - Estimated time to completion 1h39m08
jpg: 520640 recovered
Out of curiosity: Do you know whats the cause for this? Is it some border case problem, or is this "normal" for big volumes?

best, and many thanks,
Helt

The problem has probably been fixed by this commit https://git.cgsecurity.org/cgit/testdis ... a4a0e4fdfd
