I seriously doubt this is a FreeBSD issue.

Here's the relevant messages:

First, 440BX chipset, pretty standard fare. I've run hundreds of these
boxes with IDE without problems.

Western Digital slaving a Western Digital. Plus a CDROM on the
other channel.

'hard error' is generally Bad(tm). 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.
