Is there a way to manually set sector size? I think recuperabit is assuming my 4096 sector size disk has 512 sector size.

Is there a way to manually set sector size? I've got an image of a harddrive where the sector size is 4096 (because on modern harddrives that is what it is) but a lot of linux cli functions default to 512 sector size (and usually include an option flag to select an alternate sector size.)

Maybe I'm just wrong about how many sectors I have, but Recuperabit did find file/index records once every 8 sectors, which would fit with my theory. This also means recuperabit is going 8 times slower than it needs to on most modern harddrives?

Currently there is no option for this, but it's a useful request.

I mean I might be wrong, if I'm wrong the feature is useless (recuperabit is already choosing the right sector size) but if I am right? reuperabit is almost always choosing the wrong sector size (at least on modern hdds). Of course the code for this idea is way over my head :)

To clarify, currently RecuperaBit is not "chosing" any size, it is set as a constant equal to 512. 😅

Hm. I found this ticket and started wondering if it affects me. For the record, sector size can be easily seen by running fdisk. In my case, the output is:

Sector size (logical/physical): 512 bytes / 4096 bytes

I guess logical sector size is what we're looking for, right? And if that number was different, then simply editing constants.py should be enough, correct?

[Lazza]

What we are concerned with is the sector size used by the file system, not by the physical disk. If the logical size is 512, you should be OK.
