Reading Data Recovery — UK No.1 PC Computer Data Recovery Specialists (25+ years)

We provide engineering-grade recovery for desktop PCs and workstations across every brand, interface, and failure mode—from legacy PATA/SCSI to the latest PCIe Gen5 NVMe. Our workflow is clone-first, controller-aware, and forensically sound: we stabilise hardware, capture the fullest possible image, then rebuild the logical structures above it.

Top 75 desktop drive faults we recover — with how we fix them

Format: Problem summary — Lab resolution (technical)

Mechanical HDD (1–18)

1. Head crash / loud clicking — Match donor HSA by adaptives; verify SA access; per-head imaging (tiny blocks, reverse passes); blacklist scarred zones; rebuild translator if required.

6. Servo wedge damage / off-track reads — Adaptive head offset & micro-step seeks; interleave wedges; reconstruct gaps later from redundancy.

7. Preamp short (HSA) — HSA replacement; current-limited power to protect MCU; clone immediately after stabilisation.

8. Parking ramp fracture — Replace ramp; verify land/fly behaviour; conservative read profile thereafter.

9. Chassis warp after drop — True-up cover/frame; check platter parallelism; servo offset tuning; image most stable zones first.

10. Translator corruption (LBA mapping lost) — Regenerate from P/G-lists; restore user area; begin cloning with conservative timeouts.

20. TVS short / surge damage — Replace TVS/regulators; confirm rails & ripple; immediate low-stress clone.

21. Corrupt ROM/adaptives — Rebuild ROM from SA/backup; reprogram MCU; verify identity & full LBA access before imaging.

23. SAS backplane/expander CRC storms — Rehost drive; new path/cable; lock link speed; image with CRC counters.

24. Power brownouts/reset loops — Bench PSU; staged power ramps; tightened imager timeouts to keep drive responsive.

51. OPAL/SED locked — Unlock via user creds/PSID; decrypt on the clone; without keys cryptography prevents decryption (only plaintext artefact carving is possible).

System / RAID / Desktop-specific (67–75)

67. Drive not recognised / BIOS errors — Isolate I/O path; force conservative modes on the imager; clone ignoring OS timeouts.

68. UEFI/bootloader corruption — Repair boot chain on image; export user data; optionally make a bootable copy to target media.

69. Overheating under load — Bench-cool; staged imaging; throttle QD; resume after stabilisation.

Firmware & electronics repair

We restore access via ROM/EEPROM transfers, firmware module patching, disabling problematic features (e.g., background relocation/SMR cache), or donor component swaps (PCB, preamp, voltage regulators). All operations precede imaging and are validated on a bench PSU with current limiting.

Mechanical interventions

Where needed, we perform head-stack replacements, motor/spindle swaps, platter migrations and alignment using matched donors and adaptive calibration. Imaging then proceeds per-head with conservative, skip-on-error strategies.

Logical / data-layer recovery

We reconstruct NTFS, HFS+, APFS, EXT, XFS, ReFS, exFAT, Btrfs, ZFS; replay journals, rebuild catalogs/B-trees, and content-carve media/video (MP4/MOV container rebuild from mdat), databases and mail stores. Complex cases (BitLocker/FileVault/LUKS) are decrypted on the clone with valid credentials/keys.

Verification & delivery

Every job is validated with SHA-256 hash manifests, sample-open testing, and secure handover (encrypted if required).
