How does professional data recovery work?

Professional data recovery typically involves:

1. Analysis: The failed HDD or SSD is inspected for external and internal damage.
2. Diagnosis: Engineers determine the type of failure (mechanical, logical, electrical) and assess the success chances.
3. Data extraction: If feasible, data is imaged and reconstructed with specialized tools.
4. Validation: Recovered data is verified to ensure integrity and completeness.

A clean environment (cleanroom procedures) is often required—especially for mechanical issues—to avoid contaminating sensitive platters.
