Best software to test my hard drive for problems?

[NKDietrich]

One of my WD 250GBs recently started clicking and performing terribly, so I stopped using it and replaced it with a Seagate 7200.10 250GB. Now, the WD drive looked fine in some SMART data reader I was using, but I didn't want to risk using it and losing data.

Now I've got the clicking again. I don't know if its the other WD or the Seagate but I'd like to test each of them to make sure they are okay.

SpinRite (free d/l i think) will diagnosis. HDDtach will tell you its performance.

SpinRite is payware and HDTach does not work in Vista.
