I have the hdd part of a "fusion drive", where the ssd part died. When trying to inspect the APFS container on that hdd, I encounter several checksum validation errors, up to the part where there is no block in the entire checkpoint descriptor area, that can pass validation.
Now I'm wondering if I can simply try proceeding with a superblock, thats not been verifiable, after all I'm only trying to access the drive read-only, in order to recover data.

I have the hdd part of a "fusion drive", where the ssd part died. When trying to inspect the APFS container on that hdd, I encounter several checksum validation errors, up to the part where there is no block in the entire checkpoint descriptor area, that can pass validation.
Now I'm wondering if I can simply try proceeding with a superblock, thats not been verifiable, after all I'm only trying to access the drive read-only, in order to recover data.
