Zorluk: OrtaData Destruction and Disposal Methods

An IT technician is preparing to decommission several company workstations containing a mix of Solid-State Drives (SSDs) and enterprise Magnetic Hard Disk Drives (HDDs). Company policy requires that all data on the retired drives be rendered completely unrecoverable according to NIST sanitization guidelines before handing the hardware off to a third-party recycler, and that proof of disposition be retained for regulatory compliance. Which of the following steps should the technician take to satisfy these requirements? (Select TWO.)

  1. Perform an ATA Secure Erase command on the SSDs to purge all flash memory blocks.Cevap
  2. Obtain and archive a formal Certificate of Destruction from the recycling vendor detailing drive serial numbers.Cevap
  3. C
    Degauss the solid-state drives using a high-intensity electromagnetic field prior to physical recycling.
  4. D
    Execute a standard full OS format on all drives to securely overwrite data and clear partition structures.

Cevap

The technician should perform an ATA Secure Erase on the SSDs to purge the flash memory blocks and obtain a formal Certificate of Destruction detailing serial numbers from the recycling vendor.
ATA Secure Erase sends firmware-level commands to reset all storage blocks on solid-state drives, rendering the data completely unrecoverable while keeping hardware compliant with sanitization standards. Additionally, obtaining a Certificate of Destruction provides legal and auditing proof that specific hardware assets were destroyed or sanitized according to established standards.

Adım Adım Çözüm

1
Identify media types and select appropriate sanitization methods.
Recognize that SSDs require logical purging methods like ATA Secure Erase or physical shredding, whereas magnetic media can be degaussed or shredded.
Degaussing is ineffective on flash memory storage (SSDs).
2
Execute drive sanitization commands.
Run ATA Secure Erase directly through drive firmware commands to reset flash blocks.
Standard OS formatting leaves data recoverable, whereas firmware-level ATA commands ensure complete data erasure.
3
Obtain compliance documentation.
Collect a signed Certificate of Destruction from the disposal vendor listing all drive serial numbers.
Retaining official audit logs fulfills corporate policy and regulatory compliance requirements.
