New PSU Wiped Hard Drive?

I bought a EVGA SuperNOVA 850w G2 and installed it this past Friday. When I booted it up, the BIOS came up normally and then hit a black screen. After a few seconds, I received an error code (white text on black background) that said something about Windows having failed and to use the Windows Installation/Recovery CD to fix it. Well, I put it on a flash drive because my Windows installation CD is at my parent's house (which is three hours from where I currently live).

I messed around inside the BIOS and with the recovery, but I couldn't get it to load my OS (command prompt could see my partitions, though...). When I loaded the HDD into another desktop machine, none of the contents were visible. The WD diagnostic tool said that there were "too many bad sectors," which usually means the hard drive is toast.

My question is this: Does anybody know how this happened? The PSU doesn't seem to be faulty because I can get to the BIOS, so the motherboard is good, and there doesn't seem to be a problem with the CPU or memory or anything. The hard drive worked fine before I switched power supplies. My other question is: If I take a hard drive from, say, a laptop, and plug it into my desktop, should I be worried that the laptop hard drive will get fried, too?

PSU: EVGA SuperNOVA 850w G2

RAM: 4x2GB G.SKILL NS 240-pin DDR3 1333
Monitor: ASUS VH242H 23.6in
Fans: One stock 120mm fan, 3 Cougar 120mm and 1 140mm blue LED hydraulic

I agree with junkeymonkey. I'm guessing that this was coincidental and that if the PSU was bad you would be burning out other components as well, but the only way to know is to try, unless you know how to use a multitester/volt meter and know what to test for.

Use your own discretion. Personally, I'd try it out after making a backup of the laptop drive.

It definitely was not a static charge as I always ground myself and anything I think will be a problem. I don't see how I could've damaged the drives. I've handled lots of hard drives before without any problem, but maybe I just messed this one up? I also meant to say in the introductory post that I've tried different SATA and power cables (and in different slots on the PSU, since it's modular, and the motherboard), but to no avail.

like us all ''first time for everything''

bottom line is the drive is damaged and you need a new one ... also if theres nothing on the drive to worry about contact wd and they may want to have it to check and may send you a new one in its place

I understand the drive is bad now. Most of the important data that was on it is backed up, so I'm not that worried about recovery.

I believe the WD is still under warranty, so I'm going to contact them.

I'm just concerned about putting another drive in it, but I guess the problem was with the hard drive the whole time, so putting the laptop drive in should be fine?

Right, I know that. I'm asking if I should be worried about putting the laptop drive in when my desktop drive just died after installing a new PSU.
