In the most general case i would have a where-to-mount directory with
lots of directories for the various partitions (here 10 drives with
20 partitions each).
But thankfully I don't have to deal with the most general case as I am as compulsive about giving all partitions a reasonably unique label as Debian is about assigning UUIDs. 

I sketched a procedure in my response to rhkramer.
I have errands that must be run. When I return I will check to see if your scripts catches anything mine doesn't. 





For once:

   mkdir /media/all_sd_dir
   for i in a b c d e f g h i j
   do
     for j in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
     do
       mkdir /media/all_sd_dir/sd"$i""$j"
     done
   done

Then i'd use a variation of the proposed loop (in a script, of course):

   for i in /dev/sd[a-j][1-9] /dev/sd[a-j]1[0-9] /dev/sd[a-j]20
   do

     # Skip unresolved patterns which still contain brackets
     if echo "$i" | fgrep ']' >/dev/null
     then
   continue
     fi
# Skip already mounted partitions 
     if mount | grep '^'"$i"' ' >/dev/null
     then
   continue
     fi

     # Obtain the drive letter and partition number from /dev/sd path
     dp=$(echo "$i" | sed -e 's/\/dev\/sd//')

     # Now try mounting and report success if mount did not fail
     if mount "$i" /media/all_sd_dir/sd"$dp"
     then
       echo "======= mounted:  $i  /media/all_sd_dir/sd$dp"
     fi
   done

Next, one could try to identify the content by skilled guessing and
create symbolic links to the mounted directories. (The risk is high
to end up with an systemd+udev revenant.)


Have a nice day :)
