did you recently add any disks to your system?
it's possible you are looking at the wrong disk and/or partition
xfs_repair should find any valid superblocks on the partition if there
is any.
try this quick test
dd if=/dev/hdd1 bs=512 count=1 |hexdump
you should seem output similar to this:

The 4658 4253 is XFSB and the magic number for an xfs file system.
