Throbbing hard on

Can't remember if i've mentioned this here before or not but...

One of my hard drives 'throbs' and makes annoying 'whhommmm whhommm' sound whenever it's spun up. I initially thought it was a graphics cards fan I got at the same time as this hard and thus ignored it for ages. When I transferred the drive into my entirely new PC though, the throbbing carried on and thanks to Windows power management shutting the drive off now its a secondary drive, i've pinned this annoying pulsing on the hard drive. It sounds like rather than spinning at 7200rpm its consistently revving between 7000rpm and 7400rpm or similar.

I emailed WD as it is within their warranty period but not Scans any more and they replied asking to do some tests which predictably enough passed, because sector wise it's fine.

So, my plan is to send them a link to this sound file and this image. Do you think it will get the point across? Whilst it might be fine as far as SMART cares, it's clearly not spinning properly or vibrating excessively or something and thus causes the case to vibrate and make that noise.

What do you lot think?

edit - i'll point out that I haven't managed to record the very low 'whhommm' noise that I can hear constantly, just the case vibrating (I think it's the blanking plates at the front) which sometimes happens along with the 'whhommm', more so when it's cold.
