23 This driver supports reporting the temperature of disk and solid state
24 drives with temperature sensors.
26 If supported, it uses the ATA SCT Command Transport feature to read
27 the current drive temperature and, if available, temperature limits
28 as well as historic minimum and maximum temperatures. If SCT Command
29 Transport is not supported, the driver uses SMART attributes to read
30 the drive temperature.
36 Only the temp1_input attribute is always available. Other attributes are
37 available only if reported by the drive. All temperatures are reported in
38 milli-degrees Celsius.

41 temp1_input Current drive temperature
42 temp1_lcrit Minimum temperature limit. Operating the device below
43 this temperature may cause physical damage to the
45 temp1_min Minimum recommended continuous operating limit
46 temp1_max Maximum recommended continuous operating temperature
47 temp1_crit Maximum temperature limit. Operating the device above
48 this temperature may cause physical damage to the
50 temp1_lowest Minimum temperature seen this power cycle
51 temp1_highest Maximum temperature seen this power cycle
