Hard disk drive health inspection tool

GSmartControl is a graphical user interface for smartctl (from smartmontools
package), which is a tool for querying and controlling SMART (Self-Monitoring,
Analysis, and Reporting Technology) data on modern hard disk drives. It allows
you to inspect the drive's SMART data to determine its health, as well as run
various tests on it.

GSmartControl can let you know in advance of failing that the drive has
errors. Since a hard drive which has errors can be slower as well as fail at
any time, it can help you justify spending time to back up your data or
upgrade your hard drive.
