First of all, what does
# fdisk da0
say? Has there already been a try to run fsck for this disk?
Which layout (slices, partitions) should the disk contain?
In case you lost "just" a partition table, install the program
"testdisk" from ports or packages.
If you don't have a backup of the data on the disk, keep in mind
that everything you do is basically able to do more damage. If
you have enough hard disk space, make a dd copy of the whole disk
first and continue working with this 1:1 copy.
Before you start using forensic tools, you should try to get
the disk back into action. If this fails, we'll talk about how
to recover files. :-)
