• Intelligent Detection: Automatically detects and configures appropriate tools for your hardware

🧪 SMART Testing & Analysis (New in v3.0)

• Automated SMART Tests: Runs short SMART tests on all discovered drives
• NVMe Health Monitoring: Critical warnings, temperature, available spare, and wear percentage
• RAID Drive Testing: SMART testing via MegaRAID passthrough for drives behind RAID controllers
• SSD Life Remaining: Displays wear level and estimated life remaining for SSDs
• Comprehensive Attributes: Power-on hours, reallocated sectors, pending sectors, temperature
• Health Assessment: Color-coded health status with actionable recommendations

🛠 Hardware RAID Analysis

• Virtual Drive status, RAID levels, and usable capacity
• Physical drive health with accurate state reporting (Online, Failed, etc.)
• Complete drive inventory with model numbers, serial numbers, and firmware versions
• Distinguishes between raw disk capacity and RAID-usable capacity
• Multi-controller support with detailed per-controller analysis

🖥 System Information

• Network interface inventory with hardware details
• Hardware controller detection and configuration
• Root privilege and OS validation

⚡ Smart Installation

• Installs required packages only when missing (nvme-cli, dmidecode, smartmontools)
• Automatic StorCLI detection and installation for hardware RAID controllers
• Non-intrusive operation - no unnecessary package installations

📊 Comprehensive Reporting

• Health Summary: Overall system storage health with color-coded status indicators
• Issue Categorization: Critical errors, warnings, and informational notices
• Actionable Recommendations: Specific guidance for addressing detected issues
• Predictive Analysis: Early warning for potential drive failures based on SMART attributes

Recent Improvements

🚀 Version 3.0 - SMART Testing & Advanced Health Analysis

• Comprehensive SMART Testing: Automated short SMART tests on all drives with progress monitoring
• NVMe Health Metrics: Detailed analysis including wear percentage, available spare, and critical warnings
• RAID Drive SMART Access: Full SMART testing via MegaRAID passthrough for drives behind RAID controllers
• SSD Life Monitoring: Wear level indicators and remaining life percentage for all SSDs
• Enhanced Health Assessment: Color-coded health status based on multiple SMART attributes
• Test Result Analysis: Automatic analysis of SMART test results with actionable recommendations

✅ Version 2.0 - Bug Fixes & Enhancements

• Fixed NVMe Model Names: Resolved truncated model names (was showing "INTEL" instead of full "INTEL SSDPE2KX040T8")
• Corrected RAID Parsing: Fixed StorCLI output parsing for accurate drive states, sizes, and model information
• Enhanced Size Reporting: Proper distinction between physical disk capacity and RAID virtual drive capacity
• Improved Data Consistency: Ensures identical information display for drives in the same RAID array
• Robust Error Handling: Multiple fallback methods for parsing different StorCLI output formats

🔧 Technical Improvements

• Enhanced NVMe device detection using nvme id-ctrl with intelligent fallbacks
• Corrected StorCLI field parsing based on actual command output analysis
• Improved data extraction for serial numbers, firmware versions, and capacity information
• Better formatting and presentation of storage analysis results
• SMART attribute parsing for predictive failure analysis

Usage
