S.M.A.R.T. Software, HD Tune or other?

[bigdavethehorn]

I RMA'd my 3 month old Seagate 7200.10 320GB drive and received the replacement a couple of days ago.

I'm about to be a first time S.M.A.R.T. user so that I have a little advance warning of early HDD death and I'm looking for freeware application suggestions.

So far I've found HD Tune and HD Health, any others?

What do you folk use?

I believe Seagate has it's own tool. WD Diagnostic Tools too. Speedfan does. I'm not sure if Everest does or not.
