This structure is used in conjunction with IOCTL_STORAGE_QUERY_PROPERTY to return temperature data from a storage device or adapter.
VersionContains the size of this structure, in bytes. The value of this member will change as members are added to the structure.
SizeSpecifies the total size of the data returned, in bytes. This may include data that follows this structure.
CriticalTemperatureIndicates the minimum temperature in degrees Celsius that may prevent normal operation. Exceeding this temperature may result in possible data loss, automatic device shutdown, extreme performance throttling, or permanent damage.
WarningTemperatureIndicates the maximum temperature in degrees Celsius at which the device is capable of operating continuously without degrading operation or reliability.
InfoCountSpecifies the number of STORAGE_TEMPERATURE_INFO structures reported in *TemperatureInfo. More than one set of temperature data may be returned when there are multiple sensors in the drive.
Reserved0[2]Reserved for future use.
Reserved1[2]Reserved for future use.
TemperatureInfo[ANYSIZE_ARRAY]Device temperature data, of type *STORAGE_TEMPERATURE_INFO.
