Drive Analyzer has three ways of letting you know that your drives may be in danger: AI-Based Drive Health Predictions, Faulty Drives (with NAS-Detected Errors), and Threshold-Based Alerts. These systems operate upon different mechanisms. The first system, AI-Based Drive Health Predictions, utilizes an artificial intelligence (AI) that analyzes your drive health data over time to predict whether your drive will fail in the near future. The second system, Threshold-Based Alerts, shows whether any health indicators selected by DA Drive Analyzer surpass their thresholds. The third system, Faulty Drives (with NAS-Detected Errors), identifies drives labeled by their host NAS as having poor health. This label is based on thresholds set by the NAS maker. For information on how to handle Fault Alerts, please contact the NAS maker.
