PhotoRec going back to earlier sectors - is this a bug or intended behaviour?
Posted: 04 Jan 2020, 21:08
I have a question about how PhotoRec (7.2 WIP) works that seems to come up a lot in the forums but I still haven't managed to find a direct answer to. When I run PhotoRec on my 2TB disk, it sometimes seems as if the recovery is in a loop - it will suddenly reset and then go back to an earlier sector number. Analysing this behaviour with screen capture software shows that it will keep doing this, slowly increasing the highest sector that it gets to, before it eventually resets again.
I know how to solve the issue, by skipping the photorec.ses file, but the question that I am yet to find a definitive answer to is whether this behaviour of going back to an earlier sector is part of PhotoRec's intended behaviour. Is it going back to recover more data and/or finish off partially recovered files, or is it just a bug? Knowing the answer to this would help to make an informed decision on whether it's worth letting PhotoRec continue doing this to potentially recover more files or to just avoid wasting time and skip ahead a few sectors.
