What we should be looking at are the disklabels for those devices:

   disklabel /dev/da0s1

As the swap partition could be overlapping with your root partition. 
Then when your system crashed, the system wrote to the end of your
swap partition, which wrote over your root partition.

Actually, you want your swap partition as close to the center of the
hard drive as possible to minimize the movement of the drive heads,
thus increasing the speed.
