ID detection code is not the only; manufacturer can use different ID code or increase or decrease its quantity according to
the detected parameter’s quantity.
For example: the ID detection code of WEASTERN Digital’s product is “04”, parameter is Start/Stop Count, but the
parameter of same code in Fujitsu’s product is “Number of times the spindle motor is activated”.

sometimes different models in same brand maybe different ,but must ensure major test items specified in
S.M.A.R.T .(although different manufacturers have specific naming convention ,the essence of monitoring is the same.)
