Eric A. Hibbard coauthored the September2025 revision of Guidelines for Media Sanitization by Ramaswamy Chandramouli and Eric A. Hibbard with Ramaswamy Chandramouli. Its title page identifies Hibbard with Samsung Semiconductor, Inc.; the printed initial is retained without expansion.^[ref]

The guide distinguishes sanitization verification, checking the outcome of the attempted process, from sanitization validation, deciding whether that outcome adequately protects the target data.^[ref]

An original acceptance example separates those decisions. Suppose a specified process reports successful completion on all ten devices in a batch, and inspection finds no execution errors. Later assessment establishes that the selected technique is unsuitable for the particular storage technology on two devices. All ten completion records can be genuine while acceptance of the two unsuitable cases fails. The count of successful executions alone cannot establish that the target data is inaccessible at the required recovery effort.

This is a hypothetical classification example, not a procedure for erasing devices. It illustrates the joint guide's distinction between evidence of execution and the adequacy of data sanitization; the byline does not allocate particular sections to individual coauthors.

Ramaswamy Chandramouli coauthored Guidelines for Media Sanitization by Ramaswamy Chandramouli and Eric A. Hibbard, revision2, with Eric A. Hibbard in2025. The printed title page identifies Chandramouli with the National Institute of Standards and Technology's Computer Security Division.^[ref]

Their guidance classifies data sanitization by recovery resistance and the medium's future usability. In particular, destroying a medium prevents its subsequent use for data storage; this is an additional consequence beyond the intended protection of the target data.^[ref]

For an original scope example, suppose the same confidential dataset is stored on two devices. The first is successfully sanitized and recorded in an inventory, but the second remains readable. The statement that one device passed its acceptance criteria is compatible with the dataset still being recoverable from the other device. Protection of every relevant copy requires a scope that includes both devices; one certificate cannot establish a claim about an unassessed copy.

A different stipulated requirement might also demand reuse of the original medium. Destruction cannot satisfy that reuse requirement, even if it achieves the intended recovery resistance. The example shows why acceptance depends on both the information being protected and the constraints on the medium, without recommending a device-specific erasure technique.
