 # Drive Health
 
-The Drive Health page allows you to check the health of your storage drive using SMART data and a machine learning model.
+The Drive Health page combines two views of the configured backup drive:
+
+- SMART data plus the local machine-learning failure prediction
+- HDSentinel health and performance reporting
 
 ## Features
-- **Error/Warning Alerts**: Shown if SMART data is missing or the model is not loaded.
-- **Missing Attributes**: Lists any SMART attributes not available for the drive, with a warning that accuracy may be affected.
-- **Prediction Result**: Shows if a failure is predicted, with probability percentage.
-- **Run Health Check**: Button to run a new health check (submits the form).
-- **SMART Data Table**: Lists all SMART attributes, descriptions, raw values, and status (available/default).
-- **Tooltips**: Hover over info icons for detailed attribute descriptions.
-- **Download Telemetry**: Button to download SMART telemetry data.
-- **Send Telemetry**: Button to email telemetry data.
+- **Run Health Check**: Runs a manual SMART and HDSentinel refresh from the page.
+- **Prediction Result**: Shows whether the SMART model predicts failure, with probability percentage.
+- **Missing Attributes**: Lists SMART attributes that fell back to defaults.
+- **HDSentinel Status**: Shows install state, device, model, serial, health, performance, temperature, size, and last checked time.
+- **HDSentinel Settings**: Lets users enable or disable HDSentinel monitoring and toggle health-change alerts.
+- **SMART Data Table**: Lists SMART attributes, descriptions, raw values, and status.
+- **Download Telemetry**: Downloads the SMART telemetry CSV.
 
-## UI Details
-- Inline feedback for errors and missing data.
-- Table with attribute, description, value, and status.
-- Spinners and tooltips for user feedback.
+## Alerting
+- HDSentinel alerts only trigger on health changes between scheduled checks.
+- Temperature is displayed but does not currently trigger alerts.
