After testing my HDD with Hitachi Drive Fitness Test HDD, stopped working, check the PCB and i see that the diode D4 was burned.
It is possible to replace and if so someone knows that specifications have D4?

The pictures:

If you need to get data off of the drive you can remove it and extract the data to a new drive ASAP.

But I would not use this drive to hold data any more. That diode is the power protection for the drive; so when it's gone there is no more protection.

Search the forum for TVS for more info.

Thanks Russwinters, drccsc

I removed the diode, and backup data, I found valuable information here on TVS ...

Thank you

Hi Boshogot, I got the same hard drive and the printed circuit board have a different problem (it's an other chip...)
- I would like to know if it is possible for you to send me your PCB - I can pay for the shipping by paypal or other...

I got many years of work on that drive and I still don't find the same drive... I know that there is no guaranties that it will work on my hard drive because it's not the same date but I talk to a friend that said that it is working the most of the time!

Tank you in advance, my hope is rebirth -

Which chip is it? Can you provide a photo?

It could be more serious then repairing the PCB if *certain* components are damaged.
