A software developer in London encountered a critical issue when their ASUS laptop failed to boot. The laptop’s M.2 SSD was not recognized in the BIOS, leaving the client unable to access critical project files, development environments, and personal data. The developer urgently sought the help of Advanced Data Recovery, London’s leading data recovery company, to recover their valuable data.
The Problem
The M.2 SSD failure was caused by:
- Controller Failure:
- Diagnostics revealed that the SSD’s controller chip had malfunctioned, rendering the drive unrecognizable to the BIOS.
- Potential NAND Corruption:
- Corruption in the NAND flash memory could have resulted from a sudden power outage during operation.
- No Backup:
- The SSD was the primary storage device, and no backup existed, making recovery critical.
The Data Recovery Process by Advanced Data Recovery
Step 1: Initial Assessment
The team conducted a detailed evaluation:
- Physical Inspection: The M.2 SSD was visually inspected for signs of physical damage, such as heat marks or a damaged connector.
- Logical Testing: Tools confirmed the drive was not responding due to a controller failure.
- Data Preservation: The SSD was immediately handled in a controlled environment to ensure no further damage occurred.
Step 2: Controller Bypass
To access the data:
- Controller Emulation: Advanced tools were used to bypass the non-functional controller, allowing direct access to the NAND flash memory.
- Firmware Analysis: The team reconstructed the SSD’s firmware environment to emulate the drive’s original functionality.
Step 3: Direct NAND Recovery
With the controller bypassed:
- NAND Chip Access: The NAND memory chips were carefully read using specialized chip readers.
- Wear-Leveling Algorithm Reconstruction: Modern M.2 SSDs use complex algorithms to distribute data across NAND cells. These algorithms were reversed to reconstruct the logical structure of the data.
- Error Correction: ECC (Error Correction Code) algorithms were applied to recover corrupted data segments.
Step 4: Data Reconstruction
Once the raw data was extracted:
- File System Repair: The NTFS file system was reconstructed to restore the directory structure and metadata.
- File Recovery: Priority was given to the developer’s project files, source code, and personal documents.
Step 5: Validation and Delivery
- Integrity Check: The recovered files were thoroughly tested to ensure they were complete and usable.
- Secure Delivery: The recovered data was transferred to a new external SSD and securely returned to the client.
Challenges Faced
- Controller Failure: The non-functional controller required advanced techniques to emulate and bypass its functionality.
- Complex Data Layout: M.2 SSDs use advanced wear-leveling and data distribution mechanisms, making reconstruction challenging.
- Urgency: The client needed the data urgently to resume work on time-sensitive software projects.
Outcome
Advanced Data Recovery successfully:
- Recovered 98% of the data, including all project files, source code, and personal documents.
- Delivered the recovered files within 72 hours, enabling the client to meet their project deadlines.
- Provided recommendations for implementing a robust backup strategy and power protection to prevent future data loss.
Lessons Learned
- Backup Regularly: Use external drives or cloud storage to maintain backups of critical data.
- Power Protection: Use an uninterruptible power supply (UPS) to minimize the risk of power-related SSD failures.
- Seek Professional Help: DIY recovery attempts can worsen SSD failures. Engage professionals for the best recovery outcomes.
