Consolidated Master HDD System File for Reduced Boot Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data storage systems, particularly hard disc drives (HDDs), face challenges in reducing the time-to-ready (TTR) due to the lengthy process of reading multiple system files from different locations, which increases the time required for the HDD to be ready to accept host commands after power-on, especially as more system information is added.
Innovation Solution
A method is introduced to manage system files by creating a master HDD system file that contains the content of multiple disparate system files, allowing these files to be read in a single seek and revolution operation, thereby reducing TTR and enhancing HDD reliability through redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple system files are stored at different locations on storage media, then system information can be organized and stored, but the time to read all system files increases significantly
Solution Approach 1:
The patent combines multiple disparate system files into a single consolidated system file. Instead of reading from multiple separate locations, the system reads one unified file containing all system information, thereby reducing seek operations and revolution time while maintaining all necessary system data.
Solution Approach 2:
The system consolidates all system file content into a single pre-prepared master system file during manufacturing or initialization. This preliminary action ensures that during boot-up, the system does not need to perform multiple read operations, but can directly read the complete system information from one location.
2Loss of information
If multiple system files are read from different tracks during bootup, then all system information is available, but the number of seek operations and revolutions increases
Solution Approach 1:
The patent merges multiple system files containing system defects, user defects, DOS information, and other system data into a single consolidated system file. This eliminates the need for multiple seek operations to different tracks while ensuring all system information is preserved and accessible.
Solution Approach 2:
The consolidated system file serves multiple functions simultaneously - it stores system defects, user defects, DOS information, and other system data that were previously distributed across multiple files. This single file performs the role of multiple separate files, reducing access time while maintaining information completeness.
3Reliability
If system files are distributed across multiple locations, then data redundancy can be achieved, but the complexity of reading and managing these files increases
Solution Approach 1:
The patent combines multiple system files into a single consolidated file, simplifying the file management structure. Instead of managing multiple separate files with different locations and access procedures, the system manages one unified system file, reducing operational complexity while maintaining data redundancy through the consolidated structure.
Data Source
AI summary
A method or system comprises reading content of a plurality of system files from storage media of a storage device, generating a master storage device system file, and storing the master storage device system file on the storage media at a master system file location. The location of the master system file is provided to boot firmware or hardware. As a result, when the system boots up, the master system file is read into a temporary cache.
