Is there any program which can test if a hard disk is going to die soon?

I have my WD 6.4GB HD keep running for almost 3 years (24/7). It showed some bad cluster half a year ago. After a zero-filling, all the bad clusters were gone and I couldn't find any error by scandisk and norton disk doctor. However, I'm still not very confident with it.

Use IBM Drive Fitness Test. I works on Non-IBM disks just fine. If there is impending failure, it will kick back a SMART error code.
