ATA S.M.A.R.T. Attributes
Each drive manufacturer defines a set of attributes, and sets threshold values beyond which attributes should not pass under normal operation. Each attribute has a raw value, whose meaning is entirely up to the drive manufacturer (but often corresponds to counts or a physical unit, such as degrees Celsius or seconds), a normalized value, which ranges from 1 to 253 (with 1 representing the worst case and 253 representing the best) and a worst value, which represents the lowest recorded normalized value. Depending on the manufacturer, a value of 100 or 200 will often be chosen as the initial normalized value.
Manufacturers that have implemented at least one S.M.A.R.T. attribute in various products include: Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, Toshiba, Intel, STEC Inc, Western Digital and ExcelStor Technology.

Famous quotes containing the words smart and/or attributes:
“Jefferson Smith: If you thought as much as being honest as you do of being smart ...
Diz: Honest? Why, we’re the only ones who can afford to be honest in what we tell the voters. We don’t have to be re-elected like politicians.”
—Sidney Buchman (1902–1975)
“True and false are attributes of speech not of things. And where speech is not, there is neither truth nor falsehood. Error there may be, as when we expect that which shall not be; or suspect what has not been: but in neither case can a man be charged with untruth.”
—Thomas Hobbes (1588–1679)
