At a Glance
Passmark's DiskCheckup provides a great way to view S.M.A.R.T. info. It's free, and you run it only when you need it--there's no background service sucking up CPU cycles. If you don't run your PC 24/7, this is an excellent approach.
Note: This file is free for personal use only. Business users must pay $15.
