Additionally, the PD-4 is a powerhouse when it comes to ensuring the physical destruction of hard drives. Using a rugged stainless-steel crushing wedge, the PD-4 physically bends, breaks, and mangles hard drives and their internal components, including the data platters. This process prevents the hard drive from spinning up or the data platters from being removed and placed on a spin stand used in laboratory data recovery techniques. The PD-4 also cracks the hard-drive housing, breaks the PC board, and smashes the read-write heads. It's the ultimate solution for total hard drive destruction, best used after degaussing to ensure data is irretrievable.
