The invention relates to the technical field of digital storage, and provides a method and a system for recovering long-term storage failure of a mobile terminal, through the design of a built-in independent power supply, a startup disk can still supply power continuously when the mobile terminal is in a power-off state, and the limitation of traditional OTG (On-The-Go) equipment is broken through. The read-write state of the data block of the flash memory chip is automatically monitored through the storage controller, and a health report is generated in real time; and when the early warning data block is detected, a bidirectional communication protocol is triggered. In a data backup link, a boot disk adopts a hierarchical check mechanism to generate CRC codes for each data block for centralized storage, and meanwhile, an overall SHA-256 code is calculated and double-end synchronization is performed. And in the recovery stage, the backup integrity is ensured through SHA-256 code comparison, then the data accuracy is verified block by block through CRC codes, and finally, the backup file is automatically migrated to the nonvolatile partition. The seamless closed loop from fault detection to data recovery is realized aiming at the system guidance problem after long-term storage of the equipment.

This application relates to the field of digital storage technology, providing a method and system for recovering from long-term storage failures in mobile terminals. Through a built-in independent power supply design, the boot disk can continue to supply power even when the mobile terminal is powered off, overcoming the limitations of traditional OTG devices. The storage controller automatically monitors the read / write status of flash memory chip data blocks and generates real-time health reports; when a warning data block is detected, a bidirectional communication protocol is triggered. During the data backup phase, the boot disk employs a layered verification mechanism to generate CRC codes for each data block and stores them centrally, while simultaneously calculating the overall SHA-256 code and synchronizing it across both ends. In the recovery phase, SHA-256 code comparison ensures backup integrity, and CRC code verification verifies data accuracy block by block. Finally, the backup files are automatically migrated to a non-volatile partition. This achieves a seamless closed loop from fault detection to data recovery, addressing the system booting challenges after long-term device storage.
