you don't say!
but the question was, does it find (fractions) of deleted files on that (full, non-empty) part of the disk or will it show all files or find nothing?

you are talking about (your space, my space, free and used space) on the file system level, which is irrelevant to photorec, which i know!

but i am talking about the reserved space by linux and the ssd controller that will be set aside for e.g. wear leveling purposes. this space is not available ...

ok, but what happens when you search the whole disk of a healthy disk with working metadata and file system? photorec should find nothing, right?

ok, so does this mean, on a linux system, photorec will recover files even from the reserved space and even if it is started by a user/non-root?

Does Photorec recover files from the (about 5%) reserved disk space on a ext4 file system which can be accessed only from the (root) system?

E.g. if you overwrite the free disk space with zeros on a SSD, will Photorec recover deleted files from the reserved space? I assume not.

Does anyone know if ...

What sense does it make that Photorec offers recovery from non-free disk space? These files don't have to be recovered because they are visible anyway!?
Can somebody explain that?
Thx
