A small accounting firm in London encountered a severe issue when their Lenovo desktop computer failed to boot, displaying an error message indicating disk failure. The hard drive housed crucial business data, including client financial records, tax filings, and sensitive company documents.
Without a recent backup, the firm urgently contacted Advanced Data Recovery, London’s leading data recovery company, to recover their critical files.
The Problem
The Lenovo desktop hard drive failure was due to:
- Physical Disk Damage:
- The hard drive exhibited clicking noises, indicating a mechanical issue with the read/write heads.
- Logical Corruption:
- Attempts to boot the system had partially corrupted the NTFS file system, making data inaccessible even if the drive was detected.
- Critical Data at Risk:
- The hard drive contained all accounting software data, invoices, and client records, vital for the firm’s operations.
The Data Recovery Process by Advanced Data Recovery
Step 1: Initial Assessment
The recovery team performed a detailed evaluation:
- Physical Inspection: The hard drive was emitting clicking noises, confirming a failure of the read/write heads.
- Logical Analysis: Diagnostics showed the NTFS file system was partially corrupted due to repeated failed boot attempts.
- Disk Imaging: A sector-by-sector clone of the drive was initiated to secure the data before further recovery efforts.
Step 2: Cleanroom Repairs
The drive was opened in an ISO Class 5 cleanroom for component-level repair:
- Read/Write Head Replacement: Damaged heads were replaced with donor parts sourced from an identical drive model.
- Platter Stabilization: The platters were inspected for scratches and stabilized to prevent further degradation during data extraction.
Step 3: Data Imaging
Once the drive was operational:
- Sector Cloning: Advanced imaging tools were used to create a full image of the drive, bypassing damaged areas and bad sectors.
- Error Handling: Specialized tools handled unreadable sectors to maximize data recovery from degraded regions.
Step 4: Data Recovery
- File System Repair: The NTFS file system was reconstructed, allowing access to directory structures and metadata.
- Selective Data Recovery: Priority was given to financial records, tax filings, and other business-critical files.
- Complete Data Extraction: All accessible files were recovered systematically, ensuring nothing critical was missed.
Step 5: Validation and Delivery
- Data Validation: The recovered files were checked for integrity and usability, with a focus on accounting software compatibility.
- Secure Delivery: The data was transferred to a new external drive and securely delivered to the client.
Challenges Faced
- Mechanical Damage: Replacing the read/write heads required precision and expertise to avoid damaging the platters.
- Logical Corruption: The NTFS file system required advanced repair to reconstruct lost or corrupted file directories.
