Dear Friend Shahi.

My Opinion Is DCM is always not true in todays new models. and in ur issue like no S/A access i think ur donor model and other things u did matched but u dont care about rom microcode matching.
in the new model this happend no S/A accessa and also no give ID and other info with omb capacity.

and for head matching my method is totaly defrent then here all are doing. i know about donor compatibility in advanced that its compatible and works or not.
and not for wd almost all makes and models. works 99% acuratly all the time. checking method takes just 10 minut.

Thank you.

Yours Friend.
