7.4.2 S.M.A.R.T.

This section allows the user to see Self Checks on how different parameters of the Hard Drive behave.
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology: Often written as SMART) is a monitoring
system included in computer hard disk drives (HDDs) and solid-state drives (SSDs) that detects and reports on
various indicators of drive reliability, with the intent of enabling the anticipation of hardware failures.
HDD ID: Allows to select the Hard Drive that is going to be checked or just select the Hard Drive to see it's statistics.
Self-check State: Status of the Self-check Test progress, if it was stopped or not detected.
Temp: Temperature of the Hard Disk Drive.
Whole Evaluation: Final Status of the evaluation.
Self-check Type: Allows the user to select the check type to perform:
Short: Checks the electrical and mechanical performance as well as the read performance of the disk.
Electrical tests might include a test of buffer RAM, a read/write circuitry test, or a test of the read/
write head elements. Mechanical test includes seeking and servo on data tracks. Scans small parts
of the drive's surface (area is vendor-specific and there is a time limit on the test). Checks the list of
pending sectors that may have read errors, and it usually takes under two minutes.
Long: A longer and more thorough version of the short self-test, scanning the entire disk surface with
no time limit. This test usually takes a long time, depending on the read/write speed of the drive and
its size.
Conveyance: Intended as a quick test to identify damage incurred during transporting of the device
from the drive manufacturer to the computer manufacturer.
Utility Time(d): Amount of time that the Hard Disk Drive has been powered on in days.
Check: Prompt a Self-Check of the hard drive by clicking on Check.
