Storage Medium Management Device for Automatic Defective Block Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing storage medium management systems require manual replacement of congenital defective block identification, which can lead to errors and loss of necessary data due to the potential overwrite of identification during user usage, increasing maintenance costs and complexity.
Innovation Solution
A storage medium management device that automatically updates congenital defective block identification during replacement, utilizing a CPU, memory, auxiliary storage, and a controller to manage defective blocks and error information, ensuring accurate identification and registration of defective blocks across storage media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of congenital defective block identification is performed, then maintenance flexibility is maintained, but maintenance cost and error risk increase
Solution Approach 1:
The storage medium management device automatically reads the congenital defective block identification from the replaced storage medium and updates the defective block management table without requiring manual intervention from maintenance personnel, enabling the system to service itself during replacement operations
Solution Approach 2:
The system performs preliminary actions by automatically reading the defective block identification before the replacement is completed and pre-updates the management table, ensuring that the identification is updated before any data operations begin, thus preventing potential overwrite errors
2Quantity of substance
If congenital defective block identification is stored in a usable block, then storage space is optimized, but the risk of overwrite by user increases
Solution Approach 1:
The system introduces an intermediary mechanism where the controller reads the congenital defective block identification from the storage medium and transfers it to the defective block management table, acting as a mediator between the identification storage and the management system to prevent direct user access and potential overwrite
Solution Approach 2:
The system extracts the congenital defective block identification from the usable block and relocates it to the defective block management table, separating the identification data from the user-accessible storage area to prevent accidental modification while maintaining storage efficiency
3Productivity
If automatic update of defective block identification is implemented, then maintenance cost is reduced, but device complexity increases
Solution Approach 1:
The controller performs multiple functions including reading the congenital defective block identification, updating the defective block management table, and managing normal block allocation, consolidating these operations into a single multi-functional component to avoid adding separate complex systems

AI summary
A storage medium management device may include a non-volatile storage, an error information register, and a congenital defective block identification register. The storage stores a defective block identification indicating a location of a defective block in a plurality of storage media. The error information register stores error information indicating that an error has occurred in access to the plurality of storage media. If at least one of the plurality of storage media has been replaced, the congenital defective block identification register identifies based on the error information a replaced storage medium of the plurality of storage media, reads a congenital defective block identification indicating a location of a congenital defective block from a prescribed block of the storage medium replaced, and updates the defective block identification of the replaced storage medium, with the congenital defective block identification read out from the replacing storage medium.
