Kaj je to S.M.A.R.T.
Živijo!
S.M.A.R.T pomeni Self-Monitoring, Analyses, and Reporting Technology.
To pomeni, da ta tehnologija omogoča predvidevanje na podlagi določenih
indicev, kdaj se ti bo trdi disk pokvari – po domače crknil.
Iz teh podatkov je razvidno koliko bo njegova življenska doba, koliko časa
je že delal in vse podrobne podatke o disku.
Recimo moj disk, s S.M.A.R.T tehnologijo javi naslednje podatke:
