PSU replacement + Hard Drive failure

Ok. System specs.

8370 on a Asus Sabertooth 990fx
24gb ram
3X R9 280xs
2 ssds (120 and a 240)
2 hdds (3tb WD green and 1tb WD blue)
WAS a 750w PSU. Just upgraded to 1200w EVGA Supernova or whatever. (only had one gpu before psu upgrade)

Problem: Install all hardware. Boot to windows on existing os install. No software change. All 3 gpus working in crossfire just fine.  

ONLY 1 hard drive appearing in "My Computer". the 120gb ssd with the OS on it.  In disk management I can see 
the 240 appears, failed. The 3tb appears. Failed. and the 1tb is no where to be found.

I've tried swapping cables and i've changed ports on the PSU (4available)  
NOTE: The 120gb working drive IS on a Sata power cord to itself while the other 3 share one.  
Swapped the other SSD to the same Sata cord as the working drive.
No change. 
Plugged Sata powered light into sata power cable with no working drives. Works Fine.
Unplugged and replugged SATADATA cables from mobo. Switched ports on a few. 
No change.



Just want the data off the 3tb. if i lose everything else ill live. Especially if a fresh format saves the drives themselves. But I NEED that data on the 3tb.

Stupid question on my part but are the SATA ports enabled in the BIOS ?

Not a stupid question. It actually took me many trials before i even got around to checking that. Yes all are enabled. In AHCI.  Update: Drives are appearing dead. Not seeming to spin up at all. Im somehow resisting melt down mode..hoping to go after EVGA on this one. I think this is a clear case of PSU hard drive murder.

have you got an HDD docking station or another rig to test the drives in just to be sure to be sure. Its strange that a brand new PSU would derp 2 drives 

give that a shot

I'm agreeing with you on this one. I just ordered a hot swap USB 3.0 dock. ($20) from amazon that will be here Tuesday. I will check and update. If that fails I'm looking at disassembling the 3Tb and trying to remove the diode/swap PCB/ whatever I gotta freakin do. Thanks for answering though. Again. I will update.

yes an inexpensive docking station could yield more answers

no problem. glad to help
