Difficulty: EasyData Destruction and Disposal Methods

A system administrator needs to render confidential data completely unrecoverable on several decommissioned magnetic hard disk drives (HDDs) without physically destroying the drives. Which of the following data sanitization methods should the administrator use?

  1. DegaussingAnswer
  2. B
    Standard OS formatting
  3. C
    Deleting drive partitions
  4. D
    Performing a factory reset

Answer

Degaussing is the correct sanitization method for magnetic media when physical destruction is not used.
Degaussing uses a strong magnetic field to disrupt magnetic domains on magnetic drives and tapes, rendering data entirely unrecoverable while leaving the chassis intact.

Step-by-Step Solution

1
Identify the media type and destruction requirements.
The target drives are magnetic HDDs that need full data sanitization without physical destruction.
Different storage media technologies require distinct destruction or sanitization methods.
2
Evaluate data sanitization techniques suited for magnetic storage.
Degaussing disrupts magnetic domains, completely eradicating data stored on magnetic tape and disk platters.
Degaussing permanently neutralizes magnetic alignment without physical shredding or crushing.
