R2v3, ADISA, and NAID AAA all require documented data sanitization, and they all ask for different things. R2v3 sets a recoverability threshold and requires independent verification sampling.^[1] ADISA audits the technical efficacy of the erase, on site, with forensic tools.^[2][3] NAID AAA audits the people, the access controls, and the chain of custody around the erase, and leaves the technique to the operator’s policy.^[4]

Most operations learn those differences during an audit. The better time is before one.

Most drive erase certificates are generated automatically, filed automatically, and never read by anyone until the day they matter.

That day is an audit, a customer dispute, or a data incident. And on that day the certificate is either evidence or it is a PDF with a green checkmark on it.

The difference is what's on the page.
