Top 50 USB Stick / USB Flash Drive Faults — and How We Recover Them (Technical)
Core principle: We never work on your original data. We stabilise the device just enough to acquire a forensic-grade image (controller read or raw NAND dump), then rebuild data on the clone using specialist toolchains (e.g., PC-3000 Flash, Rusolut VNR, Soft-Center, Flash Extractor).
A. Connector, PCB & Power
-
Bent/broken USB plug → Micro-solder new connector; continuity test VBUS/D+ /D- /GND; image immediately.
-
Ripped pads/traces → Reconstruct missing nets with micro-wires; underfill reinforcement; verify 90 Ω diff-pair integrity; image.
-
Shorted VBUS to data/ground → Remove debris/bridge; replace TVS; bench-supply current-limit power-up; image.
-
Blown TVS diode/ESD arrays → Replace TVS/arrays; validate 5 V rail ripple; image at reduced bus speed to reduce stress.
-
Failed 3.3 V/1.8 V LDO/PMIC → Replace regulator; confirm controller/NAND rails; image or proceed to chip-off if controller still dead.
-
Cracked PCB (flex damage) → Micro-jumpers across fractures; x-ray for via damage; image.
-
Corroded pads (liquid) → Clean (water-based flux + IPA), re-tin; replace connector; image under thermal control.
-
Reverse polarity/over-voltage → Replace protection + regulators; if controller draws abnormal current → chip-off.
B. Controller-Level Problems
-
Controller burnout (Phison/SMI/Alcor/Realtek/ChipsBank/Skymedi/SSS) → Chip-off NAND; reconstruct FTL (BCH/LDPC ECC, XOR/scrambler, interleave).
-
Firmware safe mode / boot loop → Load vendor loader (test pads/UART), export raw; if impossible → chip-off.
-
Bad FTL metadata → Read via hidden sys-areas; reconstruct mapping tables; build logical image from page merge.
-
DRAM cache failure (DRAM-based controllers) → Emulate cache tables where supported; otherwise chip-off and offline rebuild.
-
Read-only mode triggered → Image within controller limits; block reallocation disabled to preserve state.
-
Wear-levelling journal loss → Heuristic page ordering + ECC validation; align planes/dies; rebuild with temporal analysis.
-
Controller encryption (TCG Opal / vendor AES) → Requires valid credentials/keys. With keys: decrypt post-image; without: data is cryptographically unrecoverable.
C. NAND / Media Faults
-
Retention loss (long shelf) → Cold-image; voltage-stepping and read-retry matrices; maximise ECC margin.
-
Read-disturb → Lower read voltages, interleave idle cycles; prioritise weakest blocks first.
-
Program/erase disturb → Multi-pass reads; discard marginal pages by ECC score; rebuild file system from best copy.
-
Bad-block proliferation → Identify per-die weak zones; mask unusable blocks; reconstruct using remaining parity/metadata.
-
Bitline leakage / cell wear → Adjust timing/DQS; invoke alternate read levels; repeat with thermal biasing if needed.
-
Partially dead die/plane → Single-plane reads with relaxed timings; fill gaps via carving + metadata reconciliation.
-
Intermittent CE line → Re-wire CE/WE/RE/CLE/ALE to lab reader; stabilise; per-channel dump.
-
ONFI vs Toggle mismatch → Force correct mode in reader; adjust timings to avoid strobe errors; redump if needed.
-
Vendor scrambling/XOR unknown → Pattern analysis (FS signatures), dictionary/XOR map discovery; apply and revalidate.
-
SLC-mode caching on TLC → Separate high-speed cache vs TLC area; merge logically by FTL timestamps.
-
Pseudo-SLC wear levelling → Detect over-provisioning pools; include hidden LUNs in dump scope.
D. Monolithic USB & Epoxy-Potted Packages
-
Monolith, no visible pins → Decap under microscope; map pinout via continuity and IR imaging; break out VBUS/GND/D+/D-/CE/RE/WE/RB/D0..D7, CLE, ALE.
-
Under-epoxy short/open → Carefully mill epoxy; rebuild torn bond wires with conductive paint + micro-wire; connect to reader.
-
Conformal-coated industrial sticks → Gentle solvent strip; pad re-exposure; direct NAND access via needle probes; dump.
-
Multi-die monolith interleave → Detect interleave factor, page size, spare area; align channels; reconstruct order.
E. File System / Partition / Logical
-
Accidental deletion (exFAT/FAT32/NTFS/HFS+/APFS/ext) → Journal-aware recovery; $MFT/B-tree rebuild; carve slack/unallocated with path/metadata salvage.
-
Quick/Full format → Recreate partition + FS structures on clone; leverage backup FAT/MFT mirr; deep signature carve for large files (PST, MOV, CR3, etc.).
-
Partition table (MBR/GPT) loss → Infer from volume headers; build synthetic GPT; mount read-only and export.
-
Corrupt exFAT bitmap/UP-case table → Repair on clone; traverse directory entries; salvage orphan chains.
-
APFS container/header damage → Use checkpoint superblocks; reconstruct volume object map; mount RO and copy data.
-
HFS+ catalog/extent tree damage → Rebuild B-trees; carve from allocator pattern where incomplete.
-
ext4 superblock/inode map corruption → Use backup superblocks; offline fsck-like rebuild; recover orphaned inodes.
-
Large fragmented files (VMs/DBs) → Range-map reconstruction from allocator; validate via internal checksums.
-
Photo/video library corruption → SQLite repair for Photos/Lightroom; rebuild sidecars/thumbnails; export originals.
F. Security / Encryption / Malware
-
BitLocker-To-Go → Full-device image → decrypt with password/recovery key; extract files from decrypted clone.
-
FileVault-encrypted content on USB → Image → unlock with keybag credentials; copy-out.
-
Hardware-encrypted sticks (IronKey/Opal, etc.) → Image controller path; requires passcode; without it, data cannot be decrypted.
-
Malware-altered partitions → Forensic clone; neutralise; export clean data; provide IOCs if requested.
G. Host/Transfer Issues
-
“USB device not recognised” (enumeration fail) → Rebuild connector/ESD, confirm pull-ups; force-low-speed if needed; image.
-
I/O freezes / timeouts → Reduce UASP/enable BOT; throttle retries; image in short chunks with power cycles.
-
Hot-unplug write interruption → Journal reconcile on clone; recover intact files + previous versions from slack.
-
File copy interruption / CRC errors → Hardware imager with fixed block size + retry budget; verify by hash.
-
Incompatible/unsupported FS → Sector-level image; rebuild FS metadata; export data via translator.
-
Overheating thermal throttling → Active cooling; staged imaging with dwell periods; prioritise weak areas.
-
Mixed-media “combo” USB (dual USB-C/A) → Bypass faulty daughterboard; wire directly to main board or NAND; dump.
