Late reply, but maybe it's usefull.

The whine is made by lower quality bearings and the vibration caused by the irregularities of the platters. If a HDD has 7200 rpm it translates to a 7200/60=120Hz whine that is distinct. A 5400 rpm drive has a 90Hz whine computed the same way, the lower it gets the less annoying it is.

Considering these frequencies there's little chance that anything may stop them. With foam you risk moreover heating the HDD unless you ventilate it face and back. The solution would be a HDD with an RPM as low as it gets (with equal noisy bearings) or a HDD with higher quality construction.

My 2 cents.
