I seriously doubt this is a FreeBSD issue.

If it's been a while since you've power cycled this drive, it looks like it just went south on you. I would suggest downloading the Diagnostic toolset from Western Digital's site and scanning the drive for problems, and fixing them if possible. In any case your 4.4 install is probably garbage.
