Replacing the boards for my HDD's

post #1 of 9
Thread Starter 
Hi,

i had four drives mysteriously die on me all at one.. Guessing something went horribly wrong with the power supply. New Asus Z97-A 3.1 mobo and new out of the box Corsair AX860.

Anyway, went to fire the thing up and no SATA's were being recognized.. Obviously thought at first bad peripheral lead coming out the psu, so tried another slot, still no joy, tried a completely different psu (my old known to be working AX760) still no sata's, so thought to myself ok new but bad mobo, so rma'd. Got a new one the next day (thumbs up newegg) but new one was doing exactly the same thing. mad.gif

So thought highly unlikely that all four drives are dead, but i better check these drives are now ok, and took 'em to a new machine.. Low and behold, not being recognized in my other machine.. Got a two new SSD's in my new rig, and all good so far, so no idea how the old ones all died at the same time... But everything is working now. and i did change the peripheral lead to another with my fingers crossed, and it didn't kill anything.

So it looks like something some how fried all four of my drives at once.... Good that !! (sarcastic comment there)

I'm talking two SSD's and two HDD's... And ALL my stuff gone.......

I know mechanically my HDD's are probably fine... Just what can i do to possibly get the stuff back off them.. I do have a backup of my stuff, but the 3TB, i did have some stuff on there that i didn't backup.. So really would be open to buying a new pcb board and getting it so that's its once again recognized.

It's a 3.0TB Western Digital WD30EZRX

My other drive (which i have an external backup of is a Hitachi H3D200003254S

Surely there's a place that specializes in selling HDD boards ??

Never had a drive go on me before in the last 20yrs of building my own pc's, so new to this swapping of the board... i don't mind just buying a couple of new SSD's and a new 6TB HDD to get me back to where i was, but i'd like to get access to my old 3TB Western Digital WD30EZRX as that has some stuff on there that wasn't part of my backup.

Any pointers would be welcome.

The pcb has a 12V TVS diode and a 5v TVS diode for overvoltage protection. If the pcb of the hdd is in a visually good condition then probably the overvoltage protection kicked in and the rest of the hdd including the pcb is ok

You have to remove the diode for the hdd to work again. Google your hdd model to find it. Usually it's the 12v but you may have to remove also the 5v.

If the hdd starts then take all your data and you're ok. Dont keep using the hdd without the diode cause if a an overvoltage happens again it will catch fire (not kidding)
If you order a new diode and solder it, your hdd will be as good as new and you can keep using it.

Thanks,

I have a replacement drive large enough to replace my two old HDD's arriving today... So if i can just get to the diodes and snip them, and then copy across my data i'll be good to dispose of the drive afterwards.

This seems to have a good article about what you're speaking of.

Hi there.

You can try to do so if you want, but I won't recommend it. I'm not saying that not only because this is an unsupported and not recommended operation in general, but mostly because that the risk of damaging the drive further is too big and that the chance of finding an exact match of a PCB is really low due to the differences in firmware over the years.

The danger is that it may (will) have different settings for how to align the heads to the tracks on the physical disk surface, and when it tries to write anything (which it will) it will result in all your data being obliterated.

Hope this helps and feel free to ask any questions you may have.

Cheers!

Understand that... but what of the snipping of the diode recommendation and just plugging that into say an external sata docking station... Getting my stuff off and onto a new drive, then discarding the snipped drive.

Not looking into keeping the hardware once i've got what i need off it.

Unless you have any other recommendations? The drive is simply not being recognized at all by the sata port on the mobo... Say's N/A in the bios as if its not plugged in or powered up.

Don't think snipping the diodes are going to help me here.

Look at the state of these ?






What could have possibly gone wrong to do this extensive damage.... Just written them off now... All four of them... An expensive something happened. Those SSD's cost me $250 a pop, though today they're only worth less than $100... But the point remains !!!

i would definitely change the psu, although i know is a top brand

I'm amazed that power supply didn't take out your motherboard and CPU and everything else while it was busy frying your drives. Probably the 5v rail went way out of spec for some reason and did the drives in.

You could try replacing the PCB's, but don't count on success. It used to be that you could do that. Back about a dozen years ago, I had a couple of Quantum Bigfoot drives that developed a common problem with those models (other than being slower than molasses in Antarctica)--their PCB's failed. You could buy new ones on eBay for a few bucks each and revive the drives. They still were slow, but they'd work again. Unfortunately, drives are a lot more complex than they were in those days.
