Difficulty: EasyData Destruction and Disposal Methods

An IT technician is tasked with decommissioning sensitive magnetic hard drives following standard organizational security procedures. Place the following hardware disposal steps in the correct chronological order from first to last.

  1. 1Log the hard drive serial numbers in the inventory asset management database.
  2. 2Degauss the magnetic hard drives to neutralize data stored on the platters.
  3. 3Pass the sanitized hard drives through a physical shredder.
  4. 4Obtain and archive a Certificate of Destruction for regulatory compliance.

Answer

The correct sequence for drive disposal is: 1) Log the hard drive serial numbers in the inventory asset management database, 2) Degauss the magnetic hard drives to neutralize data stored on the platters, 3) Pass the sanitized hard drives through a physical shredder, and 4) Obtain and archive a Certificate of Destruction for regulatory compliance.
The secure decommissioning process begins with administrative logging of serial numbers to maintain audit capability. Magnetic degaussing follows to sanitize data content. Physical shredding then destroys the hardware itself. Finally, obtaining and archiving the Certificate of Destruction validates the completed process for compliance records.

Step-by-Step Solution

1
Identify the initial chain-of-custody administrative requirement.
Documenting serial numbers in the asset database establishes an audit trail before any physical or logical modification.
Tracking must precede destruction so the organization knows which assets are being processed.
2
Perform initial data sanitization on the magnetic media.
Degaussing disrupts the magnetic domains on the platters, sanitizing the stored data.
Sanitizing media prior to physical transport or shredding minimizes data exposure risks.
3
Execute physical destruction of the hardware.
Industrial shredding destroys the physical integrity of the platters and drive electronics.
Physical destruction prevents drive reconstruction.
4
Finalize compliance documentation.
A Certificate of Destruction is generated and logged for legal and regulatory audit purposes.
Final documentation completes the disposal lifecycle and proves compliance.
