Media-specific Purge techniques may include qualified sanitize-overwrite, block erase, or cryptographic erase; Destroy is a separate sanitization method
Purge = verified sanitize overwrite, block erase, or CE; Destruct is separate/fallbackobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Technique acceptability depends on the information-storage-medium type, device command and implementation, data sensitivity, disposition, verification, and validation |
| Caveat | Normal host overwrite is distinct from a dedicated sanitize-overwrite command. Cryptographic erase requires trustworthy key pedigree, coverage, preconditions, and successful verification. |
