Guidance written to be used
Organised by subject rather than by format, because nobody researching sanitization should have to guess whether the thing they need is filed as a guide or a checklist.
Data security & sanitization
NIST 800-88 Explained
Clear, Purge and Destroy defined, how to choose a method by media type, the verification-versus-validation distinction, and what Revision 2 changed in September 2025.
ReadChain of Custody in ITAD
The five points where custody actually breaks — four of them before equipment reaches a facility — and the six artifacts an unbroken chain produces per asset.
ReadAI infrastructure
The AI Infrastructure Lifecycle
What the evidence actually shows about retiring accelerated computing hardware — refresh dynamics, the denominator problem in every published residual figure, and where the recoverable value really sits.
ReadSanitizing AI Accelerators
NIST 800-88 Rev. 2, IEEE 2883-2022, NSA/CSS PM 9-12, R2v3 and the manufacturer erase utilities: what each covers, where each one stops, and what a defensible position looks like.
ReadInside a Retired AI Rack
The component census from published manufacturer specifications — 90 NVMe devices, 18 NVSwitches, 48 power supplies in a single rack — and what that means for inventory, sanitization and recovery.
ReadDisposition Timing Against the Depreciation Curve
Disclosed useful-life changes across major operators, the denominator problem in every published residual figure, and how the timing decision should actually be made. Observed data separated from forecast.
ReadMore is in progress — audit-ready reporting, a decommissioning checklist, and an ITAD glossary.
