MASAMUNE Update Summary: Easier Erasure Review and Evidence Checks

This update summary is for teams that erase smartphones, PCs, HDDs, SSDs, and other storage media, then need to check whether the work can be explained later.

The main improvement is simple: after erasure, it should be easier to review the result, identify the device, and keep evidence that can be shown to another team or customer.

What gets easier

• Checking after erasure: Verification-related checks are being organized so operators can see what should be reviewed after a device has been erased.
• Keeping evidence with the device: Device identifiers, logs, and verification information are easier to connect, which helps when a device is reused, resold, returned, or disposed of.
• Reducing review mistakes: Routine review steps are easier to separate from actions that need extra care, helping teams avoid accidental changes while checking erasure results.
• Preparing for audit questions: The surrounding reporting and measurement checks make it easier to explain what was erased, when it was checked, and what evidence remains.

Why it matters for erasure work

• Deleting files or resetting a device is not the same as being able to show that sensitive data was handled properly.
• When devices leave your control for resale, repair, return, or disposal, the important question becomes: can the result be checked later?
• Clearer logs and verification paths reduce the amount of manual follow-up after a batch has finished.

For teams using MASAMUNE

These updates are part of making MASAMUNE easier to use in real erasure operations: erase the device, check the result, and keep the evidence together.
