Your PSU is your hard drive's voltage regulator.
Rant about Samsung - ,,,,,,,,,,,,,,,,.
The PSU changes AC to DC current. Given a stable input, yes, the PSU will provide stable output. In a brownout condition, the PSU is not provided with the stable voltage level it needs and the DC voltage it outputs will decrease.
It may depend on the quality of the capacitors in the PSU to handle a brownout condition without decreasing voltage supplied to the computer system.
Each "Green" 2TB drive on the market (sans Hitachi's new offering) has some sort of issue. I know because I have almost all of them in my Unraid server:
2TB WD Green- New EARS version is Advanced Format which doesn't work with XP, yet old EADS version is ok (which is confusing). Also I hear it has problems with regular RAID (works with Unraid though).
2TB 5900 RPM Seagate- Bad early firmware, yet most drives are STILL not shipped with newest CC35 firmware. Because of a issue with the updater, you normally have to FORCE the firmware upgrade (unnerving)
2TB Samsung F4 - Older firmware had data loss problems!!!!!!

Plus THE SAMSUNG FIRMWARE PATCH DOES NOT CHANGE THE FIRMWARE VERSION NUMBER!!!!!!! (Such a bad problem that I refuse to use this drive)
The 2TB 7200 RPM drives are fine. My 2tb Seagate Barracuda XT is my favorite drive ever, my 2TB 7200RPM Hitachi was such a good deal I bought a second for my desktop, and even though I have never had a 2TB WD Black drive I hear they are great...
Newegg's hard drive packaging is a joke. A small sheet of bubble wrap and some packing peanuts aren't good enough. If you buy several hard drives, Newegg will even wrap them all up as a single bundle with no cushioning between the drives D:
When I buy HP hard drives for my servers, they come in individual boxes, and they're cushioned on all sides by flexible plastic. You could punt the box like a football and not damage the drive inside. Consumer drives in retail boxes are packaged the same way.
If it weren't for Newegg's massive volume, I'm sure hard drive manufacturers would just flat-out deny RMA's from drives sold by them. I'd NEVER buy a drive from Newegg that wasn't in a retail box.
I'm currently on my FOURTH Seabait LP 2TB drive. Previously RMA'd 3 in a row.
newegg just buys the bulk/20 packs and splits them up whaddya expect. now the RE4's they come in this indestructible packaging its hard to describe but i've NEVER seen a consumer drive come with so much packaging ever.
Could this be a hardware + software issue by any chance? Also, does it affect Windows users?
Its a drive issue, and the effects can be replicated on Windows machines. The solution is to update the drives:
http://www.samsung.com/global/busine...bbs_msg_id=386
http://www.samsung.com/global/busine...bbs_msg_id=387
the rest of it is just as engrishyIf identify commmand is issued from host during NCQ write command in the condition of PC ,
write condition is unstable.
So It can make the loss of written data.
thats some engrish right there...the rest of it is just as engrishy

My 2TB WD RE4-GP came in like this:
Didn't get mine from Newegg though.
I just purchased 8 samsung drives 2TB for my fileserver. I wonder how they will end up. I have UPS shipping as well from New Egg. Recipe for disaster, I know, but it will be interesting to see what happens.
those numbers do sound rather painful, keep in mind you're also only collecting data from those who decided to post a review on newegg.
