Multi-Drive Data Deletion with Unified Progress Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing capacity of hard disk drives leads to prolonged processing times for complete deletion processes, making it inefficient and difficult to manage the deletion of multiple drives simultaneously, especially in systems with multiple hard disk drives where individual deletion processes are time-consuming and complex to monitor.
Innovation Solution
A data storage apparatus with a deletion control section that executes complete deletion processes on multiple hard disk drives simultaneously, accompanied by a display control section that provides a unified progress status display, allowing for easy management and visualization of the deletion process across all drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete deletion process is performed on each hard disk drive individually, then data security is ensured, but processing time becomes excessively long
Solution Approach 1:
The patent combines multiple individual deletion processes into a single unified deletion operation that processes multiple hard disk drives simultaneously. The deletion control section coordinates the deletion across all drives in parallel, merging what would otherwise be sequential operations into a concurrent process, thereby reducing total processing time while maintaining security standards.
Solution Approach 2:
The system performs preliminary organization and coordination of deletion tasks across multiple drives before execution. The deletion control section prepares the deletion schedule and coordinates resources in advance, enabling efficient simultaneous processing without compromising the thoroughness of each drive's deletion process.
2Loss of time
If complete deletion process is performed on multiple hard disk drives simultaneously, then processing time is reduced, but management complexity increases
Solution Approach 1:
The display control section provides continuous feedback on the deletion progress of all hard disk drives. It monitors and reports the status of each drive's deletion process, allowing operators to track progress and ensure completion without manually managing each drive individually. This feedback mechanism simplifies the management of simultaneous deletion operations.
Solution Approach 2:
The deletion control section acts as an intermediary between the multiple hard disk drives and the user interface. It manages the complex coordination of simultaneous deletions internally while presenting a simplified view through the display control section, shielding users from the underlying complexity of multi-drive concurrent operations.
3Measurement precision
If individual deletion processes are monitored separately for each hard disk drive, then detailed progress tracking is achieved, but ease of operation decreases
Solution Approach 1:
The display control section serves multiple functions: it tracks the deletion progress of each individual hard disk drive with precision while simultaneously providing an aggregated overview of all drives. This multi-functional display eliminates the need for separate monitoring interfaces, allowing operators to manage all drives through a single unified interface that maintains detailed tracking capabilities.
