SMART Utility is an application to scan the internal hardware diagnostics system of hard drives. SMART (Self-Monitoring Analysis and Reporting Technology) is a system built into hard drives by their manufacturers to report on various measurements (called attributes) of a hard drive's operation. The attributes can be used to detect when a hard drive is having mechanical or electrical problems, and can indicate when the hard drive is dying. This allows time to hopefully backup, and then replace the drive.
