Abstract: In some examples, after a jack of a power supply is connected to a port of a device, a first safety chip may provide a signal that includes an amount of power sufficient to power a second safety chip located in the power supply. After receiving a message from the second safety chip, the first safety chip may send the second chip an instruction to cause relays in the power supply to transition from open to closed, causing power to be provided by the jack to the computing device. The first safety chip may repeatedly send a continue instruction requesting the second chip to keep the relays in the closed position. If the jack is disconnected from the port, the second safety chip fails to receive the continue instruction and causes the relays to transition back to the open position, stopping power from being provided by the power jack.

Abstract: Disclosed herein is an apparatus and/or device to scrape a hard disk drive (HDD) to completely and permanently erase, remove, and/or destroy digital and/or electronic data and/or information stored on and/or written to the HDD without using and/or necessitating the use of external induction. The apparatus includes a first part of a HDD scrapper mounted on an arm of the HDD and a second part of the HDD scrapper mounted on a scrapper head. The apparatus also includes a turner that simultaneously permits a turning operation of magnetic platters of the HDD and the HDD scrapper. The first part, the second part, the arm, the scrapper head, the turner, and the magnetic platters are included in an enclosure of the HDD.
