S.M.A.R.T. stands for Self-Monitoring Analysis and Reporting Technology. S.M.A.R.T. technology was developed by a number of major hard disk drive manufacturers in a concerted effort to increase the reliability of drives. It is a technology that enables the PC to predict the future failure of hard disk drives. S.M.A.R.T. technology has become an industry standard for hard drive manufacturers.
If you want more information about this, there is a good article that you can find here.
The BIOS should show the status of the SMART as good or bad. When my hdd's SMART system started indicating that is was bad it would stop in the POST to make me aware of it, and had to press an F key to continue. But I have also heard of hdds dying without ever showing the warning in the POST.
I have to agree with Enthusiast, it does sound like the hdd is dead.
