Correcting my mistake:

The healthy image file does have the X F S B at 10000000  (octal) as
fdisk had reported:
Pt#          Device  Info     Start       End   Sectors  Id  System
 8: 2gb-ubuntu.img1            4096   3915599   3911504   a  SGI xfs

4096*512=2097152 (10000000 octal):
$ od -t c 2gb-ubuntu.img | grep 10000000
10000000   X   F   S   B  \0  \0 020  \0  \0  \0  \0  \0  \0  \a   u 350

I tried to see if I can find do the same thing for jaz7.img:
Pt#    Device  Info     Start       End   Sectors  Id  System
 8: jaz7.img1            3072   2091007   2087936   a  SGI xfs

$ od -t c jaz7.img | grep 6000000
6000000  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0

I guess all those zeros are not good signs.
