Sata drives being fried.

jamman · 2 May 2015 at 13:45

My system died the other week, PSU died completely.

Replaced PSU and with new one in the sata devices all fried, 1 CD ROM and two HDD. some had smoke coming from them.

Tried removing all devices and replacing sata cables and testing on a couple of old drives and they worked ok for a few reboots then both disappeared and have both been fried to.

Thing is the PSU is new, the mobo may have been damaged when the PSU failed but it sounds odd that the mobo could cause this?

Thoughts?

Go on then, tell me what PSUs you have tried.

cronos modular 750w is the new one.

Its not one that I would ever use.

But back to my question, is it possible that with a PSU thats working that HDD's could be fried in any way by a faulty Mobo.

The PC failed due to the last PSU, and I had it tested and it was dead and this is the one that was available.

I have no idea what damage may have been done when it blew, but I would have thought if the new PSU is working then the hdd's wouldnt continue to be fried.

The cables from the motherboard to the HDD will have lower voltages than the cable from the PSU.

Could just be coincidence that the HDD with the new PSU after their experience with the old psu.

Where did you have it tested / where did you buy the new PSU?

You can't say competitors here, but does it begin with ecl?

All 3 drives in the original pc died, but I only knew that AFTER the PSU was replaced, so it might have been this new one that actually fired them.

IVe since tested and lost two more.

Now to me that says this new PSU is doing the damage as I cant imagine the mobo would be capable of doing so.

I had it tested at a local store and purchased it there. They are a decent store though.

Buy all my stuff here normally but needed it urgently.

One thingsI just relaised, might have re-used a sata power cable.

Is it possible that could have been at fault?

jamman · 2 May 2015 at 15:25

HAving had psu tested its fine, but they had issues with the cable.

Im really beginning to think that cable is the thing thats caused my issues...

stulid · 2 May 2015 at 15:30

Is it an adapter cable? mole to SATA power converter? just wondering why you are not powering the drives directly from the PSU sata connectors?

jamman · 2 May 2015 at 17:23

It was a direct cable from PSU to sata, no converters.

Ive changed the cable and so far the HDD hasnt fried so that may answer that.

PC is shutting down randomly though so still a big question mark over the mobo and/or other parts.

I'm reading this as you've reused old modular cables on a new modular PSU? Therefore the pinout was likely different and fried your SATA connected drives?

jamman · 2 May 2015 at 18:27

Yes thats about the crux of it.

The one modular cable I reused does seem to have been the cause, whether its simply because the pin layout is different I dont know. Didnt even know they could be to be honest, but it certainly explains what went on. Rather and expensive mistake to make...

Well that at least answers my question, so now I know I shouldnt lose any more fried drives.

There are still other issues, even now PC is shutting down constantly using Windows, although it seems fine under ubuntu which I dont get.
