Training Modules

🔧 1. Bad Sector Analysis & Repair (Hitachi / HGST)

Bad sectors in Hitachi HDDs often appear as:
• Gradual performance degradation
• Read instability under load
• Firmware retry loops

This module covers:
• Identification of physical vs logical bad sectors
• Safe handling of surface defects
• Controlled access strategies to minimize head stress
• Professional imaging methods for unstable Hitachi drives

Correct bad sector handling is critical for maintaining data integrity.
