Possible disk failure?

Samsung SpinPoint F3 1TB SATA-II 32MB Cache - OEM (HD103SJ) [HD103SJ]

Bought Jan 11, very rarely used. I use it as a backup for my music and videos.

Trying to access it right now and it's just making my whole computer hang/stutter. Eventually I get in to see that everything is there, but opening folders and files takes forever and makes my computer lock up.

Am I right in thinking it's on its way out?

Yes

Alright for some reason the drive is working fine today... Are there any diagnostic programs I can run to check if something is messed up? :s Sorry I'm quite ignorant when it comes to hard drives, I've never had one fail before.
