I think this is part of my new standard accessory, at least as long as I HDDs verbaue in my computer. Expand Buzzing hard drive, installing decoupler, HDD Hook, enjoy peace. Very easy. The rubber is really soft rubber unlike some other decouplers with their senseless Hartgummipfropfen, which I have already durchexerziert, and I can refer to the absence of decoupling effect only as joke articles.
