You may not know "for sure", but you can make a pretty well educated
guess. You are basically ignoring Roland's argument that disks are
well-structured.
Start by looking for the MBR partition map / disklabel / GPT. Those
are kept in well-known places, so you can greatly narrow your search
space. Use the info contained therein to find likely superblock
locations. Etc. You do not have to brute-force the entire disk. You
just have to be smart about how you search.
