MacBook Data Recovery Service – Fusion Drive File Loss & Corruption Experts

At Cardiff Data Recovery, we are Wales’s leading provider of specialist Macbook data recovery service solutions, with over 25 years of experience in recovering data from even the most complex Mac failures — including Apple’s proprietary Fusion Drive setup.

In this case, a client’s MacBook Pro had two drives configured as a Fusion Drive. Critical folders and files disappeared without warning. After visiting the Apple Genius Bar, they were told the problem was with the hard drive and advised to contact us for professional data recovery.

💻 What Is a Fusion Drive?

A Fusion Drive is Apple’s hybrid storage technology that combines a traditional HDD (hard disk drive) with a fast SSD (solid-state drive) into one logical volume. macOS automatically manages which data goes to the SSD (for speed) and which remains on the HDD (for capacity).

While efficient, Fusion Drives are highly sensitive to failure. If one component fails or becomes desynchronised, the entire volume can become unreadable, leading to file system corruption and disappearing files — exactly what occurred in this client’s case.

🛠️ Step-by-Step MacBook Fusion Drive Recovery Process

1. Device Inspection and Drive Separation

  • The MacBook is carefully disassembled to remove both the SSD and HDD components of the Fusion Drive
  • Each drive is imaged separately using write-blocked, forensic-grade hardware
  • Imaging is performed using PC-3000, DeepSpar, or similar tools to prevent further damage and ensure a full sector-by-sector clone
  • Any drive with bad sectors or read errors is stabilised with slow-read, ECC-enhanced imaging

We never work on the original drives — all recovery takes place on safe, cloned copies.

2. Fusion Drive Metadata Reconstruction

  • Fusion Drives use CoreStorage or APFS Container structures to manage the logical volume
  • Our engineers analyse metadata from both disks to determine the original Fusion structure
  • We rebuild the logical CoreStorage or APFS volume manually in a virtualised environment
  • This restores the virtual Fusion container so that macOS file system tools can access it safely

3. File System Repair and Folder Recovery

  • With the logical Fusion volume reconstructed, we check for HFS+ or APFS file system corruption
  • Journal entries, allocation tables, and extent records are scanned and rebuilt
  • Deleted or lost files are located using deep-scan carving and metadata reconstruction
  • We focus on recovering key directories, including:
    • Desktop
    • Documents
    • Downloads
    • Application data (Photos Library, Mail, Keynote, etc.)

4. Verification and Data Extraction

  • Once the file system is repaired, user data is extracted and validated for usability
  • Files are categorised and returned in their original folder structure, where possible
  • The recovered data is delivered on a secure external drive, ready for use on another Mac or Windows device

📦 Supported Systems & MacBook Models

We support Fusion Drive recovery from:

  • MacBook Pro 13”, 15”, and 16”
