What are the most significant risks that could jeopardize the success of the project?
The main risk is PCB fabrication timeline slipping, which would compress our validation testing window. We’re managing this by maintaining close contact with the vendor and having backup hand-soldering plans if machine assembly faces delays.
A secondary risk is discovering issues during electrical validation that require board respins. We’re mitigating this by thorough design review and having contingency circuits designed (like adjustable timing resistors) so we can tune parameters without a full redesign.
Were any changes made to the existing design of the system?
No design changes this week. We’re in the manufacturing transition phase, holding the design stable to get boards fabricated. Any changes discovered during validation testing will be documented and evaluated for necessity versus workarounds.
System Validation Planning
For overall system validation, we’ll test the complete use case: power cycling a failing USB drive and successfully recovering data that wouldn’t be accessible through normal means. Key validation metrics:
- Recovery success rate: Percentage of simulated failures successfully recovered (target >80%)
- Time to recovery: Total time from insertion to data extraction (target <5 minutes)
- Data integrity: Verify recovered data matches original via checksum comparison
- Compatibility: Test with multiple USB drive types and failure modes
The validation approach is straightforward – we’ll test with USB drives exhibiting known failure modes (corrupted file systems, wear-leveled failures, etc.) and measure whether FlashRescue can extract data that conventional recovery tools cannot. Success means our hardware power cycling enables data access that wouldn’t otherwise be possible. We may talk about updating metrics.
