If you have ever been worried about the possibility of hard drive failure, I have two pieces of advice for you. First of all you should always backup any important or irreplaceable stuff. Secondly, you could use a hard drive “health” monitoring program such as HDDlife.
It’s a real-time hard drive monitoring utility with alerts, malfunction protection and data loss prevention functions. HDDLife uses S.M.A.R.T. technology,(most modern drives support this) and works both for single PCs and large computer networks. S.M.A.R.T. technology was developed by hard drive manufacturers to accurately predict hard drive life span and prevent hard drive malfunctions.
HDDLife displays S.M.A.R.T. attributes in real-time and alerts you if particular hard-drive attributes exceed threshold values and are at risk. You can then backup data and/or replace endangered hard drives.It also tells you the temperature of your hard drive and you can even control the noise/performance aspects of it. It loads at Windows startup, compares new attribute values with the previous values and doesn’t use much memory. The program is extremely straightforward - so no technical knowledge of PC or hard drive technology is needed at all in order to use it. It comes in paid versions and a freeware version.
All in all, its a pretty impressive little program for anyone who wants that little bit of extra peace of mind about their stored data.
