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.

Claims (44)

1. An apparatus comprising:

a first part of a hard disk drive (HDD) scrapper mounted on an arm of a HDD;

a second part of the HDD scrapper mounted on a scrapper head; and

a turner that simultaneously permits a turning operation of one or more platters of the HDD and the HDD scrapper,

wherein the first part of HDD scrapper, the second part of the HDD scrapper, the arm of the HDD, the scrapper head, and the one or more platters of the HDD are comprised in an enclosure of the HDD;

wherein the first part of the HDD scrapper comprises a first joiner and a first socket.

2. The apparatus of claim 1 , wherein

the second part of the HDD scrapper comprises a second joiner and a second socket.

3. The apparatus of claim 2 , wherein

the first part of the HDD scrapper and the second part of the HDD scrapper are coupled to an exterior latch.

4. The apparatus of claim 3 , wherein

the first part of the HDD scrapper and the second part of the HDD scrapper are coupled to each other via a silicon ring.

5. The apparatus of claim 4 , wherein

the exterior latch permits the HDD scrapper to be released for performing the turning operation.

6. The apparatus of claim 5 , wherein

the turning operation is performed using a hex key, and

the scrapper head comprises an abrasive.

7. The apparatus of claim 6 , wherein

the turning operation causes scrapping of the one or more platters of the HDD by the scrapper head.

8. The apparatus of claim 7 , wherein

the scrapping of the one or more platters of the HDD by the scrapper head causes destruction of data stored on the HDD.

9. A hard disk drive (HDD) scrapper, comprising:

a first portion mounted on an actuator arm of a HDD;

a second portion mounted on a scrapper head; and

an independent fulcrum that permits coupling of the first portion and the second portion for operation of the scrapper head to scrape one or more platters of the HDD;

wherein the first portion and the second portion are comprised in an enclosure of the HDD, and the coupling of the first portion and the second portion permits a turning operation of the scrapper head to scrape the one or more platters of the HDD;

wherein the first portion comprises a first joiner and a first socket, and the second portion comprises a second joiner and a second socket.

10. The HDD scrapper of claim 9 , wherein

the first portion and the second portion are coupled to an exterior latch,

the first portion and the second portion are coupled to each other via a silicon ring, and

the exterior latch permits the scrapper head to scrape the one or more platters of the HDD as part of the turning operation.

11. The HDD scrapper of claim 10 , wherein

the scrapper head comprises an abrasive, and

the scrapping of the one or more platters of the HDD by the scrapper head causes destruction of data stored on the HDD.

12. A hard disk drive (HDD) scrapping device for scrapping one or more platters of a HDD, the HDD scrapping device comprising:

a scrapping mechanism, wherein a first portion of the scrapping mechanism is mounted on an actuator arm of the HDD; and

a scrapper head, wherein a second portion of the scrapping mechanism is mounted on the scrapper head;

wherein the scrapping mechanism comprises an independent fulcrum that permits coupling of the first portion and the second portion via a silicon ring.

13. The HDD scrapping device of claim 12 , wherein of the first portion and the second portion are comprised in an enclosure of the HDD.

14. The HDD scrapping device of claim 13 , wherein

the first portion comprises a first joiner and a first socket, and

the second portion comprises a second joiner and a second socket.

15. The HDD scrapping device of claim 14 , wherein

the scrapper head comprises an abrasive.
