I started a thread in motherboards but I'm confused on my drive problem, the thread is http://www.tomshardware.com/answers/id-2215976/computer...
I've replaced all cables and none of the drives are detected in my computer as well as another computer. I don't see how all three could fail. I hope the info from the other thread helps.

See if you can find them in the BIOS, as it is highly unlikely that all 3 are dead.

None are detected in bios, reset cmos and loaded defaults and still nothing

Do you have the power connectors in snugly? They can be a bit harder to plug in.

They don't even work I'm another computer, makes no sense to me, it's like random cables don't work, and the hard drives don't work. I originally wasnt able to get power, after some hassle I've gotten to build, I've had to replace cables to the case fans, dvd drive, and the 6pin pci e plug. unfortunately I don't have a spare pci e 6 pin, so i don't have the gpu in.

Go to the other computer and connect the mechanical hard drive correctly. Then, format it following these instructions:

*facepalm* I thought about it, and you can't see the drives anywhere. I'm sorry, but try contacting support. I'm sorry I couldn't help you and I'm sorry for wasting your time.

The drive isn't showing up, I don't think it's even spinning, they had all worked fine the night before.

Has anyone encountered multi drive failure? Like i had said, I was able to get things working that previously weren't, by replacing cables, but new cables aren't affecting the storage drives. Possibly a random power surge? I had a surge protector with other things plugged into it that are fine. Just not sure what could be causing this, so lost. My only option at this point is to take it to a repair shop.

Yep, while highly unlikely, it is possible for 3 drives to fail. But considering 2 are SSD's from a very reputable company, I would think something else to be wrong.

I'm back after a few days being out of state, shortly after i got back, i put in someone else's hdd into my computer and it spun, but was not detected in bios. I used those same cables to plug in my hdd right after and nothing, no spin. So i guess it is my hard drives, though i don't know if i should be concerned that the test hdd still wasnt detected, despite spinning. Guess I should rma the 2 ssds, they are barely a year old, just odd they would fail like this.

I suspect that your PSU, or incorrect cabling, has overvolted your drives. The normally results in a shorted TVS diode, which then causes the PSU to shut down. The fans may kick once just before shutdown.

Usually Samsung HDDs will survive an overvoltage. All you need to do is to locate the TVS diode and remove it with flush cutters.

See http://www.users.on.net/~fzabkar/HDD/TVS_diode_FAQ.html

and http://www.users.on.net/~fzabkar/HDD/ (photo clips)

Also see http://hddrepairing.com/downloads_n_videos/presentation...

If you need help locating the TVS diodes on your other drives, upload a detailed photo.

I removed the 12v and 5v tvs diodes and i still get no spin or any sign of life, I also see no damage in the board, nothing seems burned or darker.

Did you test the diodes before removing them?

There is a zero-ohm resistor in series with the 5V diode. This acts like a fuse when the diode goes short circuit. If this resistor is open circuit, and provided there is no other damage, you can simply flow a blob of solder over it. Test the board off the drive before reinstalling it.

I didn't test the diodes because i don't have s multimeter and it was too late to get one. Figured it wouldn't matter because taking it off would tell me whether that was the problem. I'm going to pick up a meter tomorrow. Could you elaborate on that last part you wrote? Thanks for the help.

If the zero-ohm resistor is open circuit, ie if its resistance is non-zero, then you can bridge its two ends with a blob of solder. Alternatively, you can test the drive by carefully bridging the resistor with sharp pointed metal tweezers. What you are doing is akin to replacing a fuse with a wire link, so you must be certain that there are no other problems. If you choose to replace the board, then you may need to transfer a serial flash memory chip, or its contents, from patient to donor.

Windows will only support 3 or 4 Primary Partitions. There are most likely 2 primary partitions on the boot drive. Make logical partitions of the drives and give them a letter so windows can see them. Partition Wizard (free) will convert drives/partitions from or to primary.

That might be the reason.

I put a blob over the resistor and the drive worked, and is being recognized in bios. I don't have my os on it so i can't get any further but already i can put it in another computer and get any data off that i need. I am extremely hesitant though to try this with the ssd's. If I mess it up then i can't rma them.

Please don't do anything with the SSDs until we have seen a photo of both sides of the PCB. You can at least locate the fault to confirm that they died the same way as the HDD.

My plan is just to rma the ssd's. If I take off the cover to look inside i will void the warranty, and i don't want to take that risk. I see no other way to get them working.

You can measure the resistance between +5V and Gound at the drives' SATA power pins. If it is zero ohms, then you will know that the PSU killed them, and that they probably have protection diodes. That said, many SSDs are not protected from overvoltages.

Thanks for the help, I think from here its a simple SSD swap out, still not sure whether my original PSU is shot but I can figure that out, im just glad one of the drives was saved, I can live with the rest of the lost data. Guess I'll start looking at UPS's. I hear Eaton is a good brand for those.

I have seen several threads where users have come to grief after swapping cable harnesses between two different modular PSUs. These modular connectors do not have a standard pinout, which means that you can end up with +12V on a +5V pin. I suggest you measure the voltages at each pin to confirm that there is no wiring error.

Well I'm using all the cables that came with the new PSU, I don't have any connected to the new PSU that were from the old one, if thats what you mean.
