In this premium video course, Dolphin engineer will teach how to fix the Hitachi ARM dead hdd caused by ROM contents damage or ROM chip weakness. Please note if the original data drive’s ROM chip is totally burnt or damaged or missing, the data recovery chance is very small, usually we can give up the case until very very necessary.
