With journal inside the file system:

wapbl version 0x1       location 2      flags 0x0
wapbl loc0 318565312    loc1 131072     loc1 512        loc2 3
flags   wapbl 

With journal behind the file system:

wapbl version 0x1       location 1      flags 0x0
wapbl loc0 636640256    loc1 131072     loc1 512        loc2 0
flags   wapbl 

        Kind regards
