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:
“For he is the cleanest in the use of his forepaws of any quadruped.
For the dexterity of his defense is an instance of the love of God
to him exceedingly.”
—Christopher Smart (1722–1771)
“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)
