USB flash drives like the Kingston DataTraveler Kyson are widely used for their portability and ease of use. However, they are susceptible to data loss due to logical corruption, deletion, or improper ejection. In this case, PITS Data Recovery successfully performed a Kingston flash drive recovery on a USB drive that had become unreadable after such an event.

Case Overview: USB Flash Drive Not Recognized
The client, an interior designer, stored crucial project files on her Kingston DataTraveler Kyson 128GB USB 3.2 flash drive. One day:
- The USB stick became unrecognized by her Windows PC.
- Multiple connection attempts on other computers failed.
- No backup copies of recent project files existed.
After researching professional solutions, she contacted PITS Data Recovery for help.
Technical Evaluation by PITS Data Recovery
Once the device arrived at our secure lab, our engineers performed a complete evaluation as part of the flash drive recovery process:
- Physical inspection showed the USB connector, controller, and PCB were intact.
- Voltage and continuity tests confirmed the drive was receiving power and not shorted.
- Logical failure was identified due to file system corruption, not hardware damage.
- Chip-off recovery was not needed because the controller still allowed communication.

Recovery Procedure and Tools Used
To ensure maximum data safety and accuracy, our process followed strict forensic standards:
- Created a read-only, sector-by-sector clone of the entire memory stick.
- Used proprietary low-level tools to interpret the corrupted file system (FAT32).
- Reconstructed the Flash Translation Layer (FTL) and located:
- Orphaned clusters
- Deleted directory entries
- Fragmented files
- Identified and extracted over 95% of original files, including:
- AutoCAD (.DWG)
- Photoshop (.PSD)
- PDF and Office documents
We applied the following technical safeguards:
- File integrity checks using hash verification (SHA-1)
- Signature-based validation for file completeness
- All work done using write-blocked environments
Customer Verification and Delivery
Once recovery was completed:
- A remote file verification session was arranged with the client.
- She confirmed all critical design files and project documentation were intact.
- Recovered files were:
- Transferred to a new, encrypted USB 3.2 drive
- Delivered securely with tamper-proof packaging
We also provided post-recovery recommendations:
- Always use the “Safely Remove Hardware” option
- Avoid unplugging during file transfers
- Keep cloud or local backups of all important data
