Professional recovery process (what we actually do)

1. Intake & write-protection – Record serials, baseline SMART/temperature/power profiles; attach via hardware write blockers.

2. Hardware triage – Oscilloscope/current analysis, spin-up behavior, head map tests, service area (SA) access, controller health.

3. Electronics/firmware – ROM/MCU dump, adaptive transfer (head map, P/G-lists), SA module validation (DIR/overlay/translator) and rebuild.

4. Mechanical path (HDD) – Head-stack swaps, spindle swap/platter move (orientation & clocking preserved), ramp stiction release, pre-amp checks.

5. Imaging strategy – PC-3000/DDI multi-pass cloning: head-select, zone prioritisation, progressive block size, reverse reads, timeout/backoff, unstable-media profiles.

6. SSD-specific – Controller recovery (ROM/SAFE mode), FTL mapping extraction, ECC/XOR parameters, channel/plane isolation, read-disturb mitigation, thermal control; chip-off/NAND reassembly if needed.

7. Logical reconstruction – APFS/HFS+, NTFS/ReFS, exFAT/FAT32, EXT/XFS/ZFS: journal/intent replay, B-tree/metadata rebuilds, orphan grafting, snapshot reconciliation.

8. Carving & repair – RAW/JPEG/HEIC/CR3/NEF, MOV/MP4/MKV, PST/OST, SQLite/QuickBooks, VM disks; index/MFT/catalog rebuilds, container/header repairs.

9. Integrity & delivery – SHA-256 manifests, sample opens, tree audits, secure transfer.

Common laptop failure categories & how we fix them (lab view)

Mechanical (HDD)

• Head crash/clicking → donor HSA matched by micro-code; translator rebuild; head-map imaging.

• Spindle seizure/grinding → spindle swap or platter transfer; SA calibration; clone good surfaces.

• Stiction (heads stuck to platters) → controlled release; immediate imaging with short timeouts.

• Ramp/parking failures → HSA replacement; pre-amp bias validation; per-head cloning.

• Surface wear/bad sectors → multi-pass, reverse reads, adaptive retries; logical rebuild around gaps.

Electronics/Firmware

• PCB/TVS/regulator burn → TVS replacement, ROM transfer; safe power-up & image.

• Firmware translator/SA module corruption → module rewrite, translator regeneration from P/G-lists.

• USB bridge faults (external enclosures) → bypass to native SATA/NVMe; decrypt if vendor encryption present.

SSD/NVMe

• Controller lock/firmware crash → admin reset/ROM mode, vendor procedures, L2P (logical-to-physical) recovery.

• NAND wear/ECC maxed → ECC threshold tuning, channel isolation, read-refresh; partial imaging + file repair.

• Thermal throttling → active cooling, staged reads, queue depth control.

• Power-loss metadata damage → FTL/journal reconstruction; fall back to carving if maps are irrecoverable.

Logical/File-system

• APFS snapshot/catalog damage → object map/spacemap rebuild, snapshot export, orphan extent recovery.

• NTFS $MFT/$LogFile inconsistencies → mirror graft, log replay, bitmap reconciliation, orphan reparenting.

• exFAT/FAT32 table loss → FAT recreation via cluster signature analysis.

• EXT/XFS/ZFS issues → superblock/backup superblock recovery, log/intent fixes, metaslab/txg reconciliation.

• Accidental deletion/format → unallocated scan, signature-guided carving, metadata rebuild.

System/Software

• Drive not recognised/BIOS errors → PHY/link diagnostics, 0MB bugs, firmware ID patches.

• Overheating → thermal profiling, controlled imaging windows; re-seat thermal interfaces as needed.

• Failed rebuilds (single disk from array) → clone first, then virtualise RAID for logical export.

• CCTV overwrites on laptops used for NVR → stream carving (H.264/265), GOP re-index, partial timeline export.

• Encryption (BitLocker, FileVault, LUKS) → decrypt with keys/passwords; otherwise raw carve from ciphertext-adjacent plaintext where possible.
