Hi all, i have a hitachi hard drive which is dead a few months ago, the platter spins but system doesnt boot. So i've planned to swap the platter to a new drive but am unable to find the model with same FW, I suppose FW is the firmware. Tried various online shops, everything but the FW is matching with my hdd. Fw on my hdd is 3MA but online i see lot of hitachi hdd with fw 3EA, 3MC, etc. My question is can i use these hdd with different FW for the platter swapping job? Thank you in advance for any suggestion.
