What We Recover (Physical, Electronic, Logical & System-Level)
Our engineers handle mechanical failures (head crashes, spindle faults, platter damage), electronics/firmware issues (PCB short, ROM/SA corruption), media degradation (bad sectors, surface wear, NAND wear), logical faults (deletion, format, partition loss, FS damage, encryption), and system issues (not detected, BIOS errors, overheating, failed rebuilds, CCTV/NVR ring-buffer overwrites).
Professional Recovery Process (high level)
Diagnostics & Imaging: Stabilise and clone with PC-3000, DeepSpar, Atola (head-map, reverse reads, adaptive timeouts).
Firmware & Electronics Repair: ROM transfers, SA module patching, translator rebuilds, donor PCB where required.
Mechanical Interventions: Head-stack changes, platter/motor swaps, alignment, followed by controlled imaging.
Logical/Data Recovery: File system reconstruction (NTFS, exFAT, APFS, HFS+, EXT, XFS, ReFS), metadata repair, targeted carving.
Verification & Delivery: Hash manifests, sample-open of priority files, secure handover.
50 Hard Disk / SSD Faults We Recover — and How We Resolve Them
A. Mechanical (HDD)
Head crash / clicking: Donor HSA swap → ROM/adaptive calibration → per-head imaging (slow zones, soft ECC).
Slider stiction (heads stuck): Controlled release to ramp, brief spin windows, immediate cloning.
Spindle seizure / bearing lock: Platter/hub transplant to matched chassis → full image.
Off-track reads (servo drift): Adjust adaptives/servo gain, reduce seek amplitude, head-select imaging.
Platter surface scoring: Head isolation, read around scar with narrow track profile; accept partials.
Contamination after shock: Internal clean, head swap, staged imaging (outer to inner cylinders).
Parking ramp damage: Mechanical rebuild of ramp/limiters, then conservative imaging.
Deformed top cover (impact): Lid swap, shim calibration to restore flying height, then image.
B. Electronics / Firmware (HDD)
PCB failure / TVS short: Replace TVS/fuse or donor PCB + ROM transfer; verify rails; clone.
Burnt motor driver (SMOOTH/MJ): Donor PCB + ROM; short spin windows; image.
Corrupt ROM adaptives: Reconstruct from SA copies; re-program; initialise to stable state; clone.
Service Area (SA) module corruption: Patch modules (DIR, ATA, overlay), rebuild translator; unlock LBA; image.
Reallocated/pending sector storms: Head-map imaging, high-latency retries, reverse LBA sweeps.
G-list overflow / SMART lockup: Freeze G-list in RAM, temporary disable reallocation, stabilised cloning.
Firmware bug (busy state): Vendor terminal fixes (e.g., Seagate BSY), clear logs, image offline.
C. Media Degradation (HDD)
Bad sector clusters: Multi-pass with adaptive timeouts; read-retry patterns; build error map.
Weak servo wedges: Lower RPM imaging (where supported), reduced seek; head-specific passes.
Thermal asperities: Throttled duty cycles; cooldown cycles; targeted re-reads.
Magnetic decay (old archives): Longer settle times, multiple sample reads, majority voting.
D. SSD / NVMe Specific
Controller failure (no enumerate): Vendor/test-mode access; if removable NAND: chip-off, ECC/XOR, FTL rebuild → LBA export.
FTL/translator corruption: Parse metadata, rebuild L2P map, recover logical space.
NAND wear / high BER: LDPC/BCH soft-decode, Vth read-retry tuning, temperature-assisted reads.
Power-loss during GC/writes: Rebuild mapping table from journal; salvage valid blocks, ignore half-programmed pages.
Trimmed data: Acknowledge trimmed LBAs are gone by design; recover only extents still resident in valid blocks.
SED / Opal encryption: Requires valid keys/passwords; once unlocked, image plaintext device.
NVMe namespace faults: Namespace table rebuild; export LBAs via vendor access.
E. Cables, Bridges, Enclosures
USB-SATA bridge failure (ASM/JMS): Bypass enclosure, direct-attach SATA; or swap bridge PCB (same rev).
Bridge auto-encryption (WD/Samsung portables): Use donor bridge with matching key store; decrypt stream during imaging.
Thunderbolt/FireWire cases: Replace bridge; direct media access; image raw device.
F. Logical / Filesystem
Partition table (MBR/GPT) loss: Signature scan; rebuild GPT/MBR; mount RO; extract.
NTFS $MFT/$MFTMirr corruption: Rebuild from mirror, $LogFile analysis; orphan enumeration; record repair.
EXT4 superblock/journal damage: Use backup superblocks; fsck with journal replay on image copy.
XFS log corruption:
xfs_repairwith log zero/rollback on clone; recover inodes/dirs.APFS container issues: Choose healthy checkpoint, rebuild B-trees, extract volumes/snapshots.
HFS+ catalog/extent tree damage: Rebuild catalog B-tree; salvage extents; carve missing.
ExFAT bitmap corruption: Recreate allocation bitmap from directory extents and FAT hints.
G. User / OS Events
Accidental deletion: Metadata-first restore; minimal carving to retain names/timestamps.
Quick/Full format: Deep scan previous FS; reconstruct structures; selective carve for gaps.
BitLocker/FileVault/LUKS volumes: Decrypt with provided key; reconstruct inner FS; if header damaged—use backup headers/wallets.
OS “drive not initialised”: Do not initialise; rebuild partitioning virtually, mount image.
H. System-Level / RAID / Virtual
Drive not recognised in BIOS/UEFI: SA/ROM recovery or head swap; once enumerated through tools, image.
SMART trip / imminent failure: Read-only clone with reduced queue depth; avoid in-OS mounts.
RAID member failed: Clone member; virtually reassemble array; parity/mirror logic to restore volume.
Failed rebuild (NAS/RAID): Image all members; detect rebuild cut-over; parity reconcile; mount volume.
iSCSI/NAS LUN corruption: After array reconstruction, mount LUN images; recover inner FS/VMs.
VM disk (VMDK/VHDX) corruption: Treat as raw image; repair container map; mount guest FS to extract data.
I. Power / Environment / Security
Power surge / brownout: Replace TVS/regulators; clone; fix FS inconsistencies caused by partial writes.
Overheating throttling / thermal shutdown: Staged imaging with controlled temp and duty cycle.
Malware/ransomware on drive: Clean imaging; recover clean shadow/previous versions; decrypt where feasible with keys.
CCTV/NVR overwritten data: Recover segments from ring buffer (H.264/H.265 GOP carving), prioritise unallocated tails; overwritten frames are unrecoverable—we maximise intact spans and rebuild playable clips.
