Hard disk drives
Computers, servers, recorders and storage systems.
Sensitive media · separate chain
An obsolete drive must never become an active risk.
SJR isolates storage media from the material stream and agrees the neutralisation method and evidence level with the holder based on the medium and sensitivity.
The invisible risk
Deleting a file or formatting a drive may not be enough.
Computers, servers, phones, network devices and technical systems can retain information after retirement. The medium must be identified before equipment enters dismantling.
The method depends on the medium and objective
Controlled sanitisation can preserve reuse potential. Physical destruction aims to make the medium unusable. The option is defined in the agreed service scope.
Media types
Data does not live only in computers.
Each medium is qualified by technology, condition, readability and required outcome.
SSDs & flash
Internal SSDs, USB drives, memory cards and storage modules.
Phones & tablets
Devices holding accounts, contacts, messages and personal files.
Servers & arrays
Multiple volumes, redundant drives and identifiable equipment.
Network & security
Devices that can retain configurations, logs or credentials.
Special media
Non-standard media are reviewed before a method is confirmed.
Chain of custody
Separate, decide, execute, evidence.
Continuity of handling matters as much as the final operation.
Identify
Media type, quantity, origin and expected inventory level.
Isolate
Separate from the material stream and group within the sensitive batch.
Neutralise
Sanitisation or physical destruction under the approved scenario.
Document
Record, references or certificate at the level defined in the service.
Choose the right outcome
Security and reuse potential require a conscious decision.
One scenario does not suit every medium. The choice accounts for condition, technology and the holder’s policy.
Controlled sanitisation
To consider when the medium works and reuse is intended.
Physical destruction
Physical alteration intended to make the medium unusable when required.
Combined treatment
A scenario defined for particular risks or requirements after qualification.
Appropriate evidence
Record or certificate content agreed before the work and limited to verifiable facts.
Do you have drives, servers or devices containing sensitive data?
Provide media types, quantities, inventory needs and expected outcome so the applicable scenario can be defined.
