Seagate BarraCuda Data Recovery – Buzzing Noise and Not Recognised

A freelance photographer in Edinburgh experienced a sudden failure with their Seagate BarraCuda hard drive, which started making a buzzing noise and was no longer recognized by their computer. The hard drive contained thousands of irreplaceable photos and video footage from professional shoots. The client urgently sought the expertise of Edinburgh Data Recovery, Edinburgh’s best data recovery company, with over 25 years of experience in recovering data from failed hard drives.

The Problem

The Seagate BarraCuda hard drive failure was caused by:

1. Spindle Motor Seizure:
   • The buzzing noise indicated that the spindle motor had seized, preventing the platters from spinning.
2. Read/Write Head Failure:
   • The drive’s read/write heads may have been misaligned or stuck, making data retrieval impossible through normal means.
3. No Backup:
   • The photographer relied solely on this hard drive for storing their work, making recovery essential.

The Data Recovery Process by Edinburgh Data Recovery

Step 1: Initial Assessment

The recovery team conducted a detailed evaluation:

• Physical Inspection: The buzzing noise confirmed a mechanical failure inside the drive.
• Logical Diagnostics: Since the drive was not recognized by any system, firmware or logical repairs were ruled out.
• Data Preservation: The hard drive was immediately handled in a controlled environment to prevent further damage.

Step 2: Cleanroom Repair

The drive was opened in an cleanroom to diagnose the mechanical issues:

• Spindle Motor Repair:
  • The spindle motor was found to be seized, meaning the platters were not spinning. This required precision repair to regain access.
• Read/Write Head Replacement:
  • The drive’s read/write heads were replaced with donor parts from an identical Seagate BarraCuda model.
• Platter Inspection:
  • The platters were carefully inspected for scratches or contamination before proceeding with data extraction.

Step 3: Disk Imaging

Once the mechanical repairs were completed:

• Sector-by-Sector Cloning:
  • A full clone of the drive was created to bypass any remaining physical degradation.
• Error Handling:
  • Bad sectors were managed using proprietary recovery tools to extract maximum data.

Step 4: Data Recovery

• File System Repair:
  • The NTFS file system was analysed and repaired, restoring directory structures and metadata.
• Critical File Recovery:
  • The photographer’s RAW images, edited projects, and video footage were prioritized for recovery.
• Complete Data Extraction:
  • All accessible files were systematically recovered and validated.

Step 5: Validation and Delivery

• Integrity Check:
  • Recovered files were tested to ensure they were complete and not corrupted.
• Secure Delivery:
  • The recovered data was transferred to a new external SSD, ensuring faster and more secure future storage for the client.

Challenges Faced

1. Mechanical Failure:
   • Repairing a seized spindle motor required extreme precision to avoid platter damage.
2. Head Alignment Issues:
   • Replacing the read/write heads required careful calibration to ensure data readability.
3. Urgent Deadline:
   • The photographer needed the files quickly to meet client commitments.
