New HDD vibrating more than previous one

Hey guys,

I recently (last week) bought a new Seagate 7200.14 1TB drive (ST1000DM003), and I find it's vibrating noticeably more than my previous HDD (which is still working btw), a Seagate 7200.12 500GB (ST3500418AS).
I can feel the vibration on the front panel of the case, whereas I could barely feel any vibration at all with the previous drive. It feels kinda like.... a cat's purr or something (without the hum). :p
I'm 100% positive the drive is correctly fixed.

No signs of problems though, and the drive is very silent (it's actually more silent than the previous one). It's also running cool (30ºC at 25º Ambient).
S.M.A.R.T. says the drive is healthy.

So I'm wondering if it's normal for similar drives to have such different vibration performances... Should I worry?
It's such a pain having to go through RMA and then maybe receive another one just like this (or maybe worse)...

Thanks. :)

    Doesn't sound like a big deal. What case do you have? You may have knocked something loose when you installed it. Did you make sure the front panel is seated correctly as well as anything that clips on? If everything is properly put back together, you could buy some rubber bushings or washers that go in between the bolts and the HDD to try and dampen the vibration.

    My case is an old and simple CoolerMaster Elite 335 (which I might replace by the end of the year, maybe with a Corsair 600t).
    But everything is very firm, in fact if I disconnect the HDD and turn the computer on I feel virtually no vibrations.

    I did use some 3M insulating tape I had lying around to help dampen the HDD a bit. :p
    What I did was cut two small strips of tape and put one on both sides of the drive, and cut small holes on the tape where the screws go.
    Though instead of screws I'm actually using those plastic holders, as they seem to hold it tighter than screws.

    I have it on the second to bottom bay, since my graphics card is huge and eats up most of the upper bays.

    I might give these rubber grommets a shot, I just find it weird that the old HDD didn't vibrate the case like this. I wonder if I was just lucky with the other one...
