I just recieved and formatted my new 2TB HDD. I checked smart and error tested and everything seems ok, but when I run HDtune my graphs are pretty wild. My other drives are nice and smooth, while these have big spikes.

Is this a sign of a bad drive? Should I RMA with newegg even though smart looks good and its showing no other issues?

Try disabling S.M.A.R.T. for that drive and rerun the tests.

I've wondered the same thing about one of my WD Caviar Black 1TBs.....it has a couple spikes down close to zero at the very start of the test. I can't tell if its because the drive is also the system drive, and happens to be reading or writing something else at that moment, or if its just a quirk of the drive. Like you, the SMART boxes in HDTune all show OK.

OK I swapped cables with another drive of mine that gave great graphs, booted up in safe mode, and ran it 5 times in a row. Again, it starts out great, and gets more erratic around the 3rd run, though it does seem less severe using different cables.

So can someone who really knows their stuff give me an rma recommendation? safe mode results are good, but the more i run it, the worse they get. They still aren't that bad though, at least compared to my graphs in regular win7, which are terrible. and then theres program fail count, which is at 2167 and rising, but I'm not sure how significant that is. If it matters, I formatted the drive as UPT rather than MBR.

thanks!

You mean GPT.
Do you have lots of data on it? Might wanna try reformatting it as MBR see if anything changes.

This may be due to how HDTune tests and the fact that the drive has 4K sectors.

Could you try increasing the block size? This can be done in preferences somewhere. You may also want to use a real benchmark, like CrystalDiskMark and AS SSD.

@x3style: HDTune is a RAW test; not on filesystem. It doesn't matter what is on the drive it reads raw sectors.
