Run "fsck -p /dev/rdisk2s2" or "fsck -y /dev/rdisk2s2". What are the results ?

bash-3.2# fsck -p /dev/rdisk2s2
/dev/rdisk2s2: No such file or directory
Can't stat /dev/rdisk2s2
Can't stat /dev/rdisk2s2: No such file or directory
/dev/rdisk2s2: CAN'T CHECK UFS FILE SYSTEM.
/dev/rdisk2s2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

bash-3.2# fsck -y /dev/rdisk2s2
/dev/rdisk2s2: No such file or directory
Can't stat /dev/rdisk2s2
Can't stat /dev/rdisk2s2: No such file or directory

Just an FYI here is the session I just killed to run "fsck"

looks like the dev is now rdisk1 so I ran as below

bash-3.2# fsck -y /dev/rdisk1s2
** /dev/rdisk1s2
BAD SUPER BLOCK: MAGIC NUMBER WRONG

LOOK FOR ALTERNATE SUPERBLOCKS? yes

SEARCH FOR ALTERNATE SUPER-BLOCK FAILED. YOU MUST USE THE
-b OPTION TO FSCK TO SPECIFY THE LOCATION OF AN ALTERNATE
SUPER-BLOCK TO SUPPLY NEEDED INFORMATION; SEE fsck(8).
bash-3.2# fsck -p /dev/rdisk1s2
/dev/rdisk1s2: BAD SUPER BLOCK: MAGIC NUMBER WRONG

/dev/rdisk1s2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
/dev/rdisk1s2: bash-3.2#

Looks like the remaining solution is to try PhotoRec to recover some data but original filenames won't be recovered or try some commercial data recovery tools, they may have better success in your case.
