At Exeter Data Recovery, we provide advanced and professional Compaq data recovery solutions for desktop and laptop systems, including legacy models and discontinued product lines. With over 25 years of experience, we have recovered data from thousands of Compaq systems affected by hardware failure, logical corruption, accidental deletion, and system faults.
Our data recovery engineers use forensic-grade techniques and state-of-the-art tools to extract lost or inaccessible data from failing hard drives, including both mechanical (HDD) and solid-state drives (SSD), regardless of the fault type.

Top 20 Compaq Data Recovery Faults – Technical Explanations and Solutions
Below are the most common Compaq hard disk faults we resolve, along with a detailed look at how we recover data in each scenario:
1. Accidental File Deletion
Cause: User error, software cleanup, or shift-delete.
Recovery: Scanning unallocated sectors for file headers and metadata reconstruction. File carving applied when filenames are lost.
2. Accidental Drive Formatting
Cause: Quick format or OS reinstallation.
Recovery: Sector-level scan for lost partitions; recovery of file system structures and directory mapping.
3. File System Corruption (NTFS/FAT32)
Cause: Improper shutdowns, malware, or OS instability.
Recovery: Rebuilding of boot sectors, Master File Table (MFT), and FAT tables; logical volume reconstruction.
4. Physical Drive Failure
Cause: Head crash, spindle seizure, or platter damage.
Recovery: Cleanroom disassembly; head replacement or donor swap; controlled imaging of accessible platter zones.
5. Bad Sectors
Cause: Wear, manufacturing defects, power issues.
Recovery: Imaging with advanced retry handling and sector remapping; recovery from healthy sectors first.
6. Unrecognised Disk (BIOS/OS)
Cause: Damaged PCB or firmware failure.
Recovery: Firmware repair or ROM transplant; data extraction from clone after successful communication is restored.
7. Read/Write Errors
Cause: Surface degradation or failing controller.
Recovery: Recalibration of read strategy; sector-level logging and targeted recovery from accessible regions.
8. Malware or Ransomware Infections
Cause: File encryption or corruption.
Recovery: If encrypted, data is decrypted using valid keys (when provided). In clean infections, data extracted from backups or uncorrupted clusters.
9. Data Loss During Transfer
Cause: Interruption during file move or copy.
Recovery: Temporary and orphaned file carving; extraction from unlinked clusters.
10. Controller Failure (SSD or HDD)
Cause: Chip degradation or electrical short.
Recovery: Controller replacement (if possible) or chip-off NAND extraction and data translation.
11. Liquid Damage
Cause: Spills or flood exposure.
Recovery: Component cleaning, corrosion control, micro-soldering of failed elements; clone recovered drive when stabilised.
12. Overheating Damage
Cause: Extended use without cooling.
Recovery: Temperature-controlled imaging; clone drive before failure escalates; recover file system logically.
13. SSD NAND Wear or Corruption
Cause: Write cycle exhaustion.
Recovery: Extract NAND flash and reconstruct the logical block map manually or using vendor-specific tools.
14. Unsupported or Raw File Systems
Cause: Formatted with Linux or Mac file systems.
Recovery: Cross-platform file system recognition; mount and extract using compatible forensic software.
15. Electrical Damage or Power Surge
Cause: Faulty adapter or surge from outlet.
Recovery: Replace failed protection circuits or PCB; reinitialise drive in firmware-safe mode.
16. Partition Table Corruption (MBR/GPT)
Cause: Malware, system utility failure, or accidental overwriting.
Recovery: Rebuild partition table; identify valid volume descriptors and restore mountable partitions.
17. Formatting in Unsupported Devices
Cause: Format in cameras or media players.
Recovery: Low-level scan for lost headers; file carving where structure cannot be rebuilt.
18. Overwritten Data
Cause: Reused disk space following deletion.
Recovery: Recover intact blocks; partial files may be recovered based on content signature and allocation state.
19. Broken or Bent Connector Pins
Cause: Forceful connection or mishandling.
Recovery: Replace or microsolder connector; clone drive immediately once data access is restored.
20. Factory Fault or Firmware Bug
Cause: ROM corruption or defective firmware module.
Recovery: Firmware repair using vendor-specific diagnostic tools; restore factory settings and extract data.
