Hi,

My PSU fried most of the parts in my server, I´ve recovered from that only to find that one of the harddrives have also been fried (Completely dead).

I have tried with another PCB (Not exactly the same MLC & FW as the broken drive) and the the drive spins up but is not recognized in BIOS. I think that only the PCB board is damaged, I cannot smell or see any burnt circuits. I do have a multimeter but I do not know enough about electronics to try and find the issue myself.

Maybe someone can help me?



Here are the details of the drive:

Hitachi Deskstar (7K2000)?
HDS722020ALA330
P/N: 0F10311
MLC: JPK20N
FW: 20N
Manufactured SEP-2009

What information is necessary to find a suitable replacement PCB? Do I need to move the FW circuit over to the new PCB on a Hitachi?

Are there any companies doing just PCB replacement so I can recover my data myself? I have googled and checked ebay for a suitable PCB board but to no avail, does anyone know any better place to look?

Who here is near or in Sweden that can help him out on this one? Anyone close?

BTW if it is how you say it is on here the adaptive information on the board has to be moved over to the new one. This can be done in two ways.

There are people here who sell parts and they might contact you soon on this one if one is available and they have it. Or you can check here on the forum to find a person that is close to you that could help you out in this one.

you need to transfer ROM data to good PCB.

I´ve read a bit more and it seems that it might be the TVS being faulty, where is it located and what measurements should I be reading on the multimeter?

The 8-pin component marked 25FU206 near the SATA power connector is the serial EEPROM.

LE25FU206, Sanyo, 2Mbit, 256Kx8, serial flash memory:

Here is the relevant area of your PCB:

I would set your DMM on the 200 ohms scale and measure the resistances of the components in the white boxes. I can't see for certain, but they appear to be TVS diodes and fusible resistors. If the damage was contained by the diodes, then an easy DIY fix will be possible.

Thanks for the info!

I measured the Fuse next to the 5V TVS, and it seems to have been triggered as it doesnt give a reading. The fuse next to the 12v TVS is OK (shows 0.03).

Should I measure the TVS diodes with 200 Ohm setting? I do have another setting showing a diode on the multimeter. Should I measure in both directions?

I've now replyed to his PM.

Regards/ Bosse

Well ,
Thats the Two Black Things Near the SATa Power connector One is for 12 volts protection and the other for 5 volts .
