I have a WD 2tb Desktop HDD with "continues Power Re boot " . Model : WD20EZAZ-00L9GB0. i CHANGE THE PCB, UNLOCKED PCB, MODULES 2& 32, HEAD. Still problem persist. When Block the SA with the help of Unlock PCB , then no problem(pwr re boot) and continuous spinning and i can access the SA and modules . All modules can be read without any obstacles . In ACE , there have no proper family , but i use with "ViniceR". I think you also experienced with the same family...
Thanks is Advance
