XPS 13 slightly vibrating

Got a refurbed XPS 13 a few days ago. Happy with it so far...

It came with a 160 gig 5200rpm HD. I put a 320 gig 7200prm hard-drive into the laptop. Now the laptop is slightly vibrating. I have twice removed and re-seated the 7200prm HD into the laptop. It's in there firmly, but it still slightly vibrates. The small vibration is most noticeable on the wrist rests, and the upper left side of the laptop. No vibration at all in the upper right corner of the laptop.

- How bad is this small vibration for the laptop? Should I quickly try to alleviate the small vibration, or can it wait?

- Can a XPS 13 handle a 7200rpm HD? Will all 7200rpm HDs cause a XPS 13 to slightly vibrate? If you own a XPS 13 with a 7200rpm HD, please let us know if it vibrates.

Could the vibration be a sign of the HD failing? I bought the HD a month ago.

- Could the vibration be caused by something else? There is a small chance I accidentally loosened something else in the laptop while installing the 7200rpm HD. I know it's unlikely to be something else, but it's worth asking.

 

I have a 7200rpm drive and no vibration. Might just be a faulty HD. Is the tray secured to the HD tightly and is the tray secured to the chassis tight?

 

If this is indeed just normal HDD vibration, there's no reason the laptop should not be able to take it. Besides the HDD and the fan, there are no mechanical parts in a modern laptop that'll care about these small vibrations.

The SXPS 13 can handle a 7200RPM drive. Some hard drives naturally vibrate a bit more than others, depending on platter counts, manufacturing tolerances, etc. I've owned a couple 7200RPM drives in a couple laptops, and some have vibrated more than others.

There are tons of disk checks you can do to see if your HDD is failing. There's probably a built-in disk checker in the SXPS 13 BIOS. Else, your drive's manufacturer will almost certainly have some sort of low-level diagnostics, and you can always try an OS level program like HDTune. Chances are, if your disk passes one or more of these tests, it's not failing.

Like I said, there are only two mechanical components in modern laptops, the HDD and the fan. I doubt your fan is vibrating.

 

Is the base of your laptop even?
Been a trouble before and a slightly unveven one might start the laptop to vibrate?

 

Update...

I removed the HD three more times, and re-seated it. I tightened all the screws (18 of them are involved in getting the HD properly situated. 10 for the base cover, 4 for the HD to the base, and 4 for the metal frame around the HD) as tight as I could. The vibration is a little less, but it is still there.

I tried two other HDs in the laptop, and those also cause the laptop to vibrate, although not as much as the 7200pm HD. I turned on the computer with no HD in it, and no vibration. According to my tests, any HD I put in this laptop will cause it to vibrate and some HDs cause more vibration than others.

I also ran disk diagnostics on the 7200rpm HD. The HD is fine. It passed all the tests.

Any other suggestions for how I can remove this small vibration from the laptop?
