When your MacBook gets stuck on the Apple logo during boot, it’s often a sign of an underlying issue with the Fusion Drive — a hybrid storage setup that combines a traditional hard drive with a solid-state drive. At Coventry Data Recovery, we specialise in recovering data from complex Apple storage systems including failing or partially degraded Fusion Drives.

Indicators of Fusion Drive Failure:

  • MacBook freezes at the Apple logo with a progress bar that stalls or loops.
  • Recovery mode cannot access the drive.
  • Disk Utility shows unmounted or corrupted Fusion volumes.
  • Terminal reports “Fusion Drive failed to mount” or “CoreStorage volume inaccessible.”
  • macOS Recovery options such as reinstall or Time Machine are not available.

These issues are often caused by:

  • Logical corruption of the CoreStorage volume.
  • Failure of either the SSD or HDD component in the Fusion setup.
  • File system damage (HFS+, APFS) or directory structure corruption.
  • SSD controller or NAND degradation leading to slow or no access.

🔧 Step-by-Step Technical Recovery Process

1. Safe Disassembly and Component Isolation

  • The MacBook is opened in an ESD-safe environment.
  • Both Fusion Drive components — the SSD (typically onboard) and the HDD — are identified and safely extracted.
  • We document hardware IDs and serial numbers to maintain pairing accuracy.

2. Hardware Imaging of Each Component

  • Each drive is connected to a dedicated forensic imaging platform (e.g. DeepSpar or PC-3000).
  • A bit-by-bit clone is taken from both the HDD and SSD using read-optimised recovery methods to capture all sectors — even from degraded areas.
  • Drives with bad sectors are stabilised using head skip, thermal cycling, or head swap techniques if necessary.

3. Fusion Drive Reconstruction

  • Using recovered clones, our engineers reconstruct the Fusion Drive’s CoreStorage volume structure in a controlled lab environment.
  • This includes rebuilding the Logical Volume Group (LVG) and Logical Volume Family (LVF) used by macOS to create a single logical Fusion volume.
  • Manual sector-level correction may be applied where header records or metadata structures are missing.

4. File System Repair & Logical Data Extraction

  • APFS or HFS+ file systems are verified for corruption. If needed, directory structures, catalog B-trees and journal entries are rebuilt.
  • We extract all accessible files using custom scripts and forensic recovery tools.
  • File carving techniques are applied to recover partially damaged or orphaned files not listed in the directory tree.

5. Validation & Data Delivery

  • Recovered data is validated for integrity and accuracy using file signature checks and checksum verification.
  • Data is transferred to a new external drive and made ready for secure return to the client.

💻 Supported MacBook Models & OS

We support all models equipped with Fusion Drives, including:

  • MacBook Pro (Retina, Touch Bar, and classic models)
  • MacBook and MacBook Air (with hybrid configurations via CoreStorage)
  • macOS versions from OS X Mountain Lion to macOS Ventura
