hi all..
recently i've received a seagate hdd that stop working after a thunderstorm..
in attachment i send a picture of the component that was burned (meanwhile i've changed it for a 4007 diode to test it).. and another "component" that the client damaged (i don't know how???).. both components are marqued with a blue square.
initially the hdd make a "tic tic" sound..

so i've bougth a pcb on ebay with the same serial number and when arrived i've checked that i cannot access it in windows..
but the "tic tic" sound is over.. now the sound looks like a healthy hdd but is not reconized.
i heard a sound that i plugged a usb hdd and appears in hdd management..

meanwhile i made some searches and looks like in some cases changing the pcb is not enough.. i need also to change the eeprom to match the firmware version (that i don't know from the pcb i've bought).

So i would like to ask if i can change the firmware by software or the only option is to change the eeprom?
if is need to change the eeprom wich component is? some people says that is that component marked in red circle (but it seems is like a diode, reference "E3P102 2341" and the other pcb "E3P102 2348"), but others says that is the big component saying malaysia..
changing the component is not a problem but i would like to have sure which way to go..
i'll apreciate all the help..
