Storage Medium Binding History Table Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively evaluate a storage medium in a storage device to determine if it has been used before, as recycled or second-hand storage media can lead to shorter service lifetimes and compromise the reputation of manufacturers, and there is a risk of falsified markings.
Innovation Solution
A method and system that utilize a host with a processor, storage, and communication platform to evaluate a storage medium by retrieving a binding history table, checking for multiple controllers, and using cryptographic services to verify authenticity, ensuring the storage medium has not been tampered with or reused.

Engineering Contradiction Analysis
1Reliability
If a storage medium is recycled or reused, then cost is reduced, but reliability and service lifetime are compromised
Solution Approach 1:
The system performs preliminary evaluation of the storage medium by retrieving and analyzing the binding history table before the storage device is fully assembled or sold. This preliminary action identifies whether the medium has been previously used with other controllers, allowing potential reliability issues to be detected early in the manufacturing or sales process, preventing defective recycled media from reaching customers.
2Reliability
If binding history table is retrieved and verified, then authenticity is ensured, but device complexity increases
Solution Approach 1:
The storage medium itself provides the binding history information through its internal binding history table, which records previous controller associations. The medium essentially evaluates itself by providing this historical data, reducing the need for complex external evaluation equipment. The controller and host system simply need to retrieve and verify this self-provided information using cryptographic services.
3Reliability
If cryptographic verification is performed, then security is improved, but processing time increases
Solution Approach 1:
The cryptographic verification of the binding history table is performed during the initial evaluation phase, before the storage device becomes operational. By completing this time-consuming security verification in advance, the system ensures security without impacting the operational performance or user experience of the storage device during normal use.

AI summary
The present disclosure relates to methods and systems for evaluating a storage medium. The method may include receiving, via a user interface of a host, a user request to evaluate a storage medium coupled to a first controller. The method may also include determining whether there is a first binding history table associated with the storage medium stored in the host. In response to a determination that there is no first binding history table stored in the host, the method may include retrieving a binding history table from the storage medium via the first controller and determining the storage medium as a second-hand storage medium if there is at least one second controller different from the first controller in the binding history table.
