Drilling
Platters are punctured so the drive can never spin or be mounted again.
When software cannot run
Destroy the media itself
Physical destruction is the option when a drive has no usable interface, will not boot for software erasure, or must remain unreadable even under forensic analysis.
This method is not accompanied by a Data Destruction Certificate, so it is not recommended if documented proof is required. Residual parts are recycled in full conformance with the Malaysian Department of Environment.
