Toggle a Diagnostics panel with i, built on the Activity readout. It swaps in for the Drive pane and shows the decoded critical_warning, power-on hours, power cycles, unsafe shutdowns, media errors and available spare with their change over the selection, and per-hour (Day) or per-day (History) temperature min/avg/max, active/idle/powered-off/unknown split and coverage. History bars draw reads beside writes while it is open, and a set critical_warning shows as a badge in the endurance outlook without affecting the projection. Counter deltas are withheld across a controller segment change.
