Disk Utility error: false alarm, or bad omen?

In OS X on my iMac, Disk Utility asserts that my main, internal hard drive is "about to fail" and has been asserting this for several months. But my computer is running just fine... should I worry?

The S.M.A.R.T status is failed, and the various helpful sounding options, like First Aid or Verify, are all unclickably greyed out. Using Boot Camp and HD Tune under windows, I can see the "bad" attribute is:
ID (01) Raw Read Error Rate
A different utility just names the fields slightly differently...
1, Raw Read Error Rate
Raw value: 59699
All the ther attributes (things like "seek error rate" and "spin up time" and stuff) are normal.
But my computer is running just fine. I can't work out if this is just some freaky one-time error that happened to the hard drive once which it won't forget about, reflects an existing (if seemingly benign) state of affairs, or is a sign of impending doom. This error has been present for several months now, perhaps even from The Beginning - the iMac is only 6 - 8 months old. The Man From Apple suggested I format my entire drive but that sounds pretty tedious if I don't really need to do anything / insufficient if my hard drive is actually about to die from mechanical failure.
Obviously I'd love for you all to tell me how I can safely ignore this, and even how I might be able to disabuse Disk Utility of the notion that things are messed up. On the other hand, if you think there might be trouble ahead, then do snap me out of my complacency and I'll promise not to shoot the messenger.
