Sense Condition Command (F0h) The Sense Condition command is used to sense temperature in a device. This command is executable without spinning up even if a device is started with No Spin Up option. If this command is issued at the temperature out of range which is specified for operating condition, the error might be returned with IDN bit 1. Output Parameters To The Device Feature The Feature register must be set to 01h. All other value are rejected with setting ABORT bit in status register. Input Parameters From The Device Sector Count The Sector Count register contains result value. Value Description 00h Temperature is equal to or lower than -20°C 01h-FEh Temperature is (Value/2-20)°C FFh Temperature is higher than 107°C N Not recommendable condition for start up. If over stressed condition is detected, this bit will be set to one. Travelstar 48GH, 30GN & 15GN hard disk drive specifications 162
