LOL! No, I'm running FreeBSD 8.1. I know that this all sounds too odd,
but I swear that I never messed with renaming the partitions with
labels. If you check back a few days you will see that I was having
trouble with an update, and that's where all of this happened.

To tell the truth, I'm content to leave things as they are, but
unfortunately one of the side effects of all this is that I can't figure
out how create and entry in the fstab which will again allow me to mount
my other hard drive. The former fstab entry for that was:
/dev/ad1s1 /c ntfs rw 1 0
But now with labels active I really don't know how to proceed.
