Interfaces, Protocols & Controllers We Support

• USB protocols: USB 2.0 (BOT), USB 3.0/3.1/3.2 Gen1/Gen2 (UASP/BOT), USB-C (PD negotiation), OTG dual-connector (USB-C/Lightning/Micro-B).

• Device modes: Mass-Storage BOT, UASP, composite (Mass-Storage + HID, virtual CD-ROM/LUNs), hardware encryption modes.

• Common controllers: Phison, Silicon Motion (SMI), Alcor, Innostor, Realtek, Skymedi, USBest, CBM, Norelsys, plus OEM/industrial variants.

• NAND types: SLC/MLC/TLC/QLC; ONFI/Toggle; mono/die-stack; multi-channel/interleaved; LDPC/BCH ECC.

Professional Lab Workflow (What We Actually Do)

1. Write-blocked intake & triage

   • Enumerate device (VID/PID, inquiry data, LUNs). Capture S.M.A.R.T-like vendor pages if present. Scope VBUS/DP/DM or SS pairs for link stability.

   • Decide logical vs. electronic/firmware vs. physical (connector/pad) fault. No writes to original media.

2. Stabilisation & Imaging-First

   • If device is semi-stable: hardware imager with adaptive timeouts, UASP→BOT fallback, current-limited rails, temperature monitoring. Prioritise metadata LBA ranges.

   • If unstable or dead: move to controller-level tech mode (if supported) or chip-off/monolith ISP.

3. Electronic & Firmware Work

   • PCB inspection, connector re-seat/re-solder, ESD/TVS checks, regulator rails, oscillator. Dump/patch controller firmware (microcode, mapping tables) when possible.

4. Chip-Off / Monolith ISP

   • TSOP/BGA desoldering or monolith pad exposure (micro-sanding). Identify pinout (CMD/CLK/DATs/VCC/GND) via continuity/resistance and RF probing.

   • Acquire raw NAND dumps per die/channel/plane. Record spare (OOB) bytes for ECC/metadata.

5. Flash Analysis & Logical Rebuild

   • Determine page size, block size, interleave, scramble/XOR patterns, ECC (BCH/LDPC), bad-block tables and FTL translator artefacts.

   • Reconstruct the logical image (L2P maps) then repair FAT/exFAT/NTFS/HFS+/APFS/EXT on the clone.

   • Carve fragmented files (photos/video/office/mail/VMs) with structure-aware validators and header/footer integrity checks.

6. Verification & Reporting

   • Hashes, spot-reads, openability tests (media/documents), anomaly list and any irrecoverable extents.

This workflow underpins all of our data recovery usb stick and usb stick data recovery jobs, including broken usb stick data recovery and damaged usb stick data recovery cases.

Top 30 USB Stick / Flash Drive Recovery Faults — With Technical Resolutions

Each item includes a brief summary and the lab method we use to recover data (logical, electronic and physical techniques).

1. Accidental Deletion
   Summary: Files deleted in OS; directory entries removed but data extents may remain.
   Resolution: Read-only image. Parse FS metadata (exFAT allocation bitmap/FAT chains, NTFS MFT records). Rebuild directory trees and timestamps; carve unallocated space with file-type validators; avoid mounting original.

2. Accidental Quick Format
   Summary: Boot sector/FS metadata reset; content often intact.
   Resolution: On clone, recover VBR/BPB, FSInfo; rebuild allocation tables; validate root directories; deep carve for fragmented files (e.g., MP4/ZIP/Office containers).

3. File System Corruption (FAT/exFAT/NTFS)
   Summary: Power loss during writes; inconsistent allocation maps.
   Resolution: Compare primary/backup boot sectors; bitmap vs FAT reconciliation; MFT/MFTMirr reconciliation for NTFS; journal/logfile replay; targeted carve of orphaned extents.

4. “USB Not Recognised” / Device Enumeration Fails
   Summary: Controller not responding, shorted rails, cracked connector, failed oscillator.
   Resolution: Bench-test 5V/VCC, LDO rails; rework connector; replace TVS/ESD arrays; if controller still dead → chip-off/ISP and NAND reconstruction.

5. Read/Write Errors & Freezing
   Summary: Marginal NAND, ECC saturation, bad blocks.
   Resolution: Hardware imaging with adaptive timeouts and read-retry strategy; prioritise filesystem regions; ECC decoding; majority voting across multiple reads.

6. Controller Failure (Phison/SMI/Alcor/Realtek)
   Summary: Reports 0MB, wrong size, stalls under load.
   Resolution: Enter vendor/tech mode to export raw image; if unavailable → chip-off, determine scramble/XOR, channel interleave, FTL translator from OOB markers; rebuild logical image.

7. Water / Liquid Damage
   Summary: Corrosion/shorts; no power or intermittent connect.
   Resolution: De-energise; controlled rinse, ultrasonic clean, IPA dry; replace corroded passives/connector; if controller unreliable → ISP/chip-off.

8. Saltwater / Contaminants
   Summary: Aggressive corrosion under lacquer/solder mask.
   Resolution: Extended cleaning cycle, pad re-tin; bond wires if pads lifted; move to chip-off if nets are compromised.

9. Overheating / Thermal Throttling
   Summary: Stalls under sustained writes.
   Resolution: Image at reduced clock with duty-cycle control; thermal management; capture priority metadata first; ECC-aware re-reads.

10. Electrical Damage / Overvoltage/ESD
    Summary: Blown TVS, regulator failure, damaged PHY.
    Resolution: Replace TVS/regulators; sanity-check crystals; if MCU died → chip-off and logical rebuild from NAND.

11. Broken USB Connector (Snapped Off)
    Summary: Pads torn; no enumeration.
    Resolution: Microsolder bridge to remaining pads/traces under microscope; if tracks ripped, wire-link to controller pins; if PCB cracked → chip-off.

12. Bent or Broken Pins (USB-A male)
    Summary: Short between VBUS and data lines.
    Resolution: Replace connector; inspect for PHY damage; if still dead, ISP/chip-off.

13. Cracked PCB / Flex Damage
    Summary: Mechanical stress fractures.
    Resolution: Micro-jumper severed nets; reflow. If multilayer breakage → remove NAND, read off-board.

14. Monolith USB (resin-potted) — Dead
    Summary: No serviceable connector/PCB.
    Resolution: Micro-sanding to expose buried pads; pinout discovery; ISP wiring; direct NAND dump; ECC/XOR/FTL rebuild.

15. Wear-Out / End-of-Life NAND
    Summary: High P/E cycles (installers, logging).
    Resolution: Soft-read threshold tuning (if supported), multiple-pass reads with statistical majority; ECC decode; salvage directories and critical file extents first.

16. Partition Table Corruption (MBR/GPT)
    Summary: Host sees “unallocated” / “please format”.
    Resolution: Recreate partition from FS headers (exFAT boot, NTFS MFT start). Align to cluster boundaries, then repair FS.

17. Composite Device with Virtual CD-ROM LUN
    Summary: Only CD LUN appears; mass-storage hidden.
    Resolution: Vendor commands to re-expose mass-storage; if not possible, chip-off and reconstruct.

18. Encrypted USB (Kingston Vault/DT Locker, IronKey, etc.)
    Summary: Requires credentials/hardware auth.
    Resolution: Image first; with valid credentials, decrypt on cloned image; if controller failure, chip-off and attempt decryption with recovered metadata/keys where architecture allows (some models not feasible without keys).

19. Firmware Corruption / Panic Loop
    Summary: Device enumerates then resets endlessly.
    Resolution: Tech mode entry; reload/patch firmware modules; rebuild translator tables; stabilise long enough to image.

20. File Transfer Interrupted / Unsafe Removal
    Summary: Incomplete file writes; directory inconsistencies.
    Resolution: On clone, reconcile allocation maps, fix LFN entries; salvage partial files; carve with container-aware fixups (ZIP central directory rebuild, MP4 moov/mdat repair).

21. Unsupported File System on Host
    Summary: exFAT stick used on legacy FAT32-only device.
    Resolution: Mount image with correct driver; reconstruct boot region; restore directory trees; optional non-destructive conversion on clone if needed.

22. Virus/Malware/Hidden Files
    Summary: Attributes flipped, shortcuts created, files hidden/encrypted.
    Resolution: Offline image; remove autorun and malicious entries on the clone; restore attributes; carve for originals; decrypt if keys/strain allow.

23. Overwritten Data (Partially)
    Summary: New files written after deletion/format.
    Resolution: Timeline analysis of allocation; recover intact extents; carve, then validate with signature and internal index checks; explain loss boundaries.

24. Slow Read / Timeouts Only at Certain Offsets
    Summary: Localised bad blocks or marginal die/channel.
    Resolution: Map weak regions; alter read voltage/drive strength (controller permitting); selective multi-pass; merge best segments.

25. Bad Sectors on USB Flash Drive (Logical View)
    Summary: OS reports unreadable sectors.
    Resolution: Low-level image with skip-on-error and later return; ECC-assisted reconstruction; FS rebuild from recovered metadata.

26. Short on VBUS / Device Heats Immediately
    Summary: Shorted TVS or internal controller failure.
    Resolution: Remove/replace TVS; if still short → chip-off; read NAND externally.

27. Power-Surge via Front Panel/Hub
    Summary: PHY damage; intermittent link.
    Resolution: Verify SS/HS pairs with scope; downshift to HS; stabilise long enough to image; or chip-off if PHY remains unstable.

28. CD-ROM Emulation Firmware Locked
    Summary: Stick mounts as read-only CD only.
    Resolution: Vendor tool to disable emulation; failing that, chip-off → rebuild from dumps.

29. Controller Reports Smaller Capacity
    Summary: Translator/map corruption.
    Resolution: Rebuild mapping in tech mode; or reconstruct from OOB metadata after chip-off to restore full logical span on clone.

30. Manufacturing Defect / Counterfeit
    Summary: Relabelled capacity, repeated patterns.
    Resolution: Pattern analysis on image to find true capacity; salvage valid extents; rebuild FS truncated to actual size; provide authenticity report for the client.
