Hitachi Deskstar dead PCB need Advices !!!

[Admlcamus]

Hi, First of all i´m new in this forums so plz be gentile with me… (kidding). I’m from Latin America (panama, to be exactly) and have some experience with hdd pbc swapping, and ome skill in electronics, so any idea (radical included) are welcomed. (Sorry about my grammar)

I got this situation: Recently my hdd just burned. I don’t now why, but just burned. I think it a metallic dirty around. Well, the thing is I try to change the burned electronic device but nothing. So I just call for a same hdd model, specification and everything. I got a new one with all the same specs. Change the board, and the hdd come back to live but just for the “clicking” sound. So I just turned off.

Digging around in these forums, I saw some threads about changing the burned electronics device just to get the data and get back the system with the new hdd, but I want to know first your opinions in the matter.

1- It is advisable to change the burned device from the new to the old one, so the hdd get up, back up the data and then get everything back to the normal way (old with old, new with new) or,
2- It´s better to get a exactly pcb hdd for this hdd? and if any of you have one to sell me ???
3- What other option i have in this matter.

Here I put all the info I got from the hdds (fotos)

First the Old one (the one with 3 years of data and works):

The PCB


The Data from the Bag


The Data from the Hdd Label



Here the new one, just buy it 2 days ago.

The PCb board


The Data from the Bag


And finally the Data from the hdd label


For all of you, thank on advance for your comments, help, and advices…

I really need this hdd to work just for the data to back up. Seriously you will have my eternal gratitude.

Thanks.

remove the fried pass through diode and run the hard disk on a different power supply.

Make sure it is a different power supply!

Question: can i use a external Hdd box for the test ??? or it has to be a full power supply ???? The box have its own power supply and works perfectly with another hdds... Thanks for the fast response ZA and Phisin !!!!

Use any power supply you want as long as its different.

Yes, agree.

First try the original PCB with the pass-thru diode (or TVS.....search it) removed.

If that doesn't work, you can make the new PCB compatible by moveing the NVRAM chip at U5. Without moving this chip the PCB WILL NOT work.

First of all, thank for all the responses i got from you people… finally made the hdd to work and restore the data i need (all)

I do the homework and search about the tvs, and after some preparations (get an extra external drive, extra power surge system) and go the mission. It was a success. The drive spin up normally and I can get all the data.

Thanks, very thanks for all of you for the help and assistance. I will try to fix, another hdd I got from various customers and then try to study more about this tvs to help people here… thank all you !!!
