Hard Drive going Kaput?

The hard drive machine that I am running FreeBSD on has been making some clicking sounds for quite some. The clicking is not nearly as loud (and has not become louder) as the Seagate drive that went belly-up on me last year but I still decided to back everything up and pull the drive. In the interim, I'll use the other machine, which is running Slackware, as my backup server. While I am a Linux enthusiast, I do prefer FreeBSD to Slackware. I think the clincher for me is the package manager and FreeBSD ports collection. Installing packages under FreeBSD is really straightforward and rivals, in my opinion, Arch Linux's pacman in ease of use and functionality.
