In response to the issues of data loss and system control failure caused by upper computer hard disk damage in in-dustrial control systems,this paper designs a hard disk isolation repair device.In this device,the upper computer sends read re-quests through the USB3.0 chip,and based on the request type,forwards the request to the extended SATA chip or the main control chip,ultimately retrieving hard disk data.This isolation repair device effectively prevents the system from loading the damaged hard disk's startup code,improving data recovery speed and stability.The designed device supports multiple hard disk read/write methods and power monitoring functions.This is of significant importance for ensuring the normal operation of industrial control systems and enhancing enterprise production efficiency.
