Unfortunately...

Ok, Than i might misunderstood you.
There is nothing that i could do to get more reliable results when restoring a trim enabled ssd?

I could mount the ssd back into my old computer and try to disable trim in osx recovery mode via the Terminal and than try the scan again.
I wonder if i could adress the very ssd from my other computer via terminal and change the trim settings or is necessary to put the ssd back into my old computer?

That won't help. TRIM enabled on that computer has already affected file recovery chances.

I currently have the ssd (that I want to recover from) connected via an sata adapter to an other mac.
but iam not sure how to address that drive and disable the trim settings via the terminal.

The problem is not with TRIM in your current computer. The problem is that the computer where the SSD was originally installed almost surely had TRIM enabled.

good to know.

Deep black means the existing partition.

Thanks for pointing out.

For now i tried scanning with a) all filesystems selected and b) only with apfs selected - as far as i can see with the same outcome. In both cases i get missing/invisible files and aliases instead of wav files. After i recovered a bunch of folders that include subfolders i realized that some subfolders where missing too. So it seems not to be (wav) file but also folder related.
Hmm…
Anything else i could try?

And apfs filesystem btw.

This article explains what is a possible cause of this problem: File Recovery Specifics for SSD and Other Devices Supporting the TRIM/UNMAP command.

Yes it is.
