Can't mount my hammer filesystem

I was using dragonfly bsd 2.8 x64 with 2 hard drives. Each hard drives
were hammerfs powered and one hdd was a backup of the other with
pfs-master / pfs-slave. The system was on a usb flash disk and it was
just very slow and too little .
So I deciced to format the master drive to install the system on and
then get back my data from the slave. But, that's not cool, when I try
to mount I get this message "Not a valid HAMMER filesystem".
Did I destroyed the filesystem by installing the bootblock on both disks ?
Can I get my data back ? How ?
I tried some commands unsuccessfully :
# hammer -f /dev/serno/S1PZJ1DQ508109.s4 recover /media/dd2/
hammer: setup_volume: /dev/serno/S1PZJ1DQ508109.s4: Header does not
indicate that this is a hammer volume
# hammer -f /dev/da1s4 recover /media/dd2/
hammer: setup_volume: /dev/da1s4: Header does not indicate that this
is a hammer volume
# mount_hammer /dev/da1s4 /media/dd2/
/dev/da1s4: Not a valid HAMMER filesystem
mount_hammer: mount /dev/da1s4 on /media/dd2/: Inappropriate file type or format
# mount_hammer /dev/da1 /media/dd2/
/dev/da1: Not a valid HAMMER filesystem
mount_hammer: mount /dev/da1 on /media/dd2/: Inappropriate file type or format
I have been searching into the mailing list archives or the man and I
can't find something related to my problem
