This technology reports on a variety of hard drive attributes. You need a compliant BIOS and SCSI and/or IDE controller, a hard drive that supports SMART, and some sort of software package that reports on these conditions. Once you have that, you should be able to receive system warnings about your hard drive. Many hard drive manufacturers have added onto the SMART technology or changed it around so that it has proprietary features for their drives. The good news about SMART is that having SMART is much better than not having it, and you can be warned of hard drive failure before it happens and backup your drive while it still works. Thus, your data is safer with SMART around.
