At Exeter Data Recovery, we offer comprehensive and professional HGST data recovery services for all Hitachi Global Storage Technologies (HGST) hard drives and solid-state drives. Our engineers have over two decades of experience recovering data from both legacy and enterprise-grade HGST drives across all sectors — home, business, industrial, and governmental.
We recover data from all major HGST drive types, including SATA HDDs, SAS drives, PCIe and NVMe SSDs, and legacy IDE/PATA models. Whether your drive has suffered from mechanical failure, firmware corruption, or logical damage, our lab is equipped to diagnose and recover your data using advanced, non-destructive methods.

Top 30 HGST Hard Drive Faults and Technical Recovery Methods
Our lab is equipped to resolve the most complex hard drive and SSD issues. Below are the top 30 HGST data loss faults and the technical steps we take to recover your data:
1. Mechanical Failure (Spindle/Head Crash)
Recovery: Cleanroom disassembly; head stack or spindle motor replacement; full platter imaging using stable donor components.
2. Bad Sectors / Surface Degradation
Recovery: Sector-by-sector cloning using Deepspar or PC-3000; sector remapping and retry algorithms to extract data from failing media.
3. Firmware Corruption
Recovery: Use vendor-specific firmware repair tools (e.g. PC-3000) to reload or patch corrupted microcode modules.
4. Logical Corruption (File System Failure)
Recovery: Rebuild MFT or partition headers; recover file system structure using raw volume scanning.
5. PCB (Printed Circuit Board) Failure
Recovery: Replace board with identical donor; transplant ROM chip containing unique calibration data.
6. Drive Not Recognised by BIOS/System
Recovery: Diagnostic interface access to recover firmware logs; re-enable drive initialisation if locked in safe or kernel mode.
7. Power Surge / Electrical Failure
Recovery: Inspect and replace damaged TVS diodes and capacitors; PCB repair and imaging after stabilisation.
8. Platter Damage
Recovery: If damage is minimal and peripheral, recover undamaged sectors; if extensive, advise on partial recovery.
9. SSD Controller Failure
Recovery: Recover NAND via chip-off and rebuild translation layer (FTL); use vendor tools for reassembly of logical data.
10. NAND Flash Wear (SSD Degradation)
Recovery: Read degraded NAND blocks directly using error correction (ECC); reconstruct files from surviving blocks.
11. Accidental File Deletion
Recovery: Perform unallocated space scan; recover deleted files based on residual metadata and file signatures.
12. Accidental Drive Formatting
Recovery: Scan entire drive surface for recoverable file structures and rebuild partition tables.
13. Encrypted Drive Failures
Recovery: Extract encrypted sectors; decrypt using customer-provided key or BitLocker credentials if available.
14. Overheating Events
Recovery: Clone under thermal control; recover stable file system from cloned image.
15. Unsupported File Systems (e.g., XFS, EXT4)
Recovery: Use Linux-compatible forensic tools to mount and extract files from alternative file systems.
16. Drive Lockout Due to Firmware Password
Recovery: Bypass firmware-level ATA lock using secure unlock protocols or vendor-specific methods.
17. Partition Table Corruption (GPT/MBR)
Recovery: Identify and rebuild valid partitions using offset analysis and signature recovery.
18. Drive Initialisation Failure
Recovery: Reinitialise via firmware diagnostic tools; recover accessible user data after successful startup.
19. Unresponsive SSD (No Power Response)
Recovery: Use bench voltage testing; access controller via JTAG/UART if available.
20. Factory Firmware Bug
Recovery: Patch or downgrade firmware using service tools; reload operational microcode from matched donor.
21. Media Wear in Enterprise HDDs
Recovery: Recover sectors with maximum retry logic; stabilise read behaviour using power-managed imaging.
22. Header / Metadata Damage
Recovery: Rebuild headers using backup copies or carve data directly from raw sectors.
23. Clicking or Beeping Noises
Recovery: Indicates mechanical fault; requires immediate cleanroom inspection and component replacement.
24. SATA Connector Damage
Recovery: Micro-soldering of broken contacts or transfer to donor shell for access.
25. SMART Trip or Drive Disabled
Recovery: Bypass SMART lockouts and access firmware utility area; clone drive in read-only mode.
26. System Crash During Write Operation
Recovery: File system repair; recovery of temporary file structures and pending writes.
27. SSD Boot Loop or Controller Hang
Recovery: Extract NAND manually; emulate controller functions to reconstruct logical structure.
28. Bit Rot / Silent Data Corruption
Recovery: Verify integrity with checksum algorithms; reconstruct files from partial data.
29. Unexpected Power Off / Unsafe Ejection
Recovery: Scan for uncommitted writes or corrupted journal entries; recover orphaned data blocks.
30. Incorrect Firmware Update
Recovery: Restore previous firmware image using vendor utility or recover from image with functional firmware.
