The Retired Sentry Drive Becomes a Traceable Archive

The Night Watchman had replaced his Sentry node’s two-year-old drive the previous week. The new drive had taken over daily operation, but the old one still occupied a corner of his desk. He had to decide whether to treat it as discarded hardware or keep its records available for a later check.

While clearing the desk, he labeled the old drive, wrote down its final sync height, and put it in a drawer. Someone asked why a retired drive was worth keeping. He explained that, if they ever needed to check the node’s state before the replacement, they should at least know which old record to look for.

The label turned a loose spare part into an archive with a clear history and connected it to the before-and-after restart records from the replacement day. The Night Watchman planned to note its storage location in the maintenance directory. No one knew when the old data might be needed, but they would not have to guess which drive was in the drawer.
