Overview

HDD SMART (Self-Monitoring, Analysis, and Reporting Technology) UEFI driver. Enumerates ATA/ATAPI devices, issues IDENTIFY and SMART commands via the ATA Pass-Through Protocol, and exposes drive health results through HII configuration forms. Provides a periodic timer that polls drive status and issues a notification when a predictive failure condition is detected.

Key Functions

• HddSmartDriverEntry -- Module entry point; initializes the HDD SMART instance and registers HII forms
• HddSmartAtaIdentify -- Issues ATA IDENTIFY command to enumerate drive capabilities
• HddSmartReadData -- Issues SMART READ DATA command to retrieve drive health attributes
• HddSmartPollTimer -- Periodic timer callback that checks drive status for predictive failures
• HddSmartNotificationHandler -- Handles predictive failure notification and user alert
• HddSmartFormCallback -- HII form callback for displaying SMART data in setup

Protocols / Dependencies

• EFI_ATA_PASS_THRU_PROTOCOL -- Low-level ATA command interface
• HII_CONFIG_ACCESS_PROTOCOL -- Configuration form callbacks
• HII_DATABASE_PROTOCOL -- HII package list management
• HII_PACKAGE_LIST_PROTOCOL -- IFR form data storage
• UEFI Boot Services -- Timer event for periodic polling
