Data Recovery USB Stick

With 25+ years of forensic flash experience, Sheffield Data Recovery recovers data from all USB flash drives—consumer, professional and industrial. We handle every failure mode: accidental deletion, controller firmware faults, bent/broken connectors, monolith damage, water ingress, short circuits, and more.

How to send your device: place the USB stick in an anti-static sleeve (if available), cushion it well in a padded envelope or small box, include your contact details, and post or drop it in. Diagnostics are free; we confirm findings and options before proceeding.

Our USB Flash Recovery Methodology (what we actually do)

1. Forensic intake & write-protect
   Record device descriptors (VID/PID, serial, capacity), controller family (Phison/SMI/Realtek/Alcor/Maxiotek/JMicron), and NAND type (MLC/TLC/QLC). All work is done on write-blocked hardware—no writes to the original.

2. Non-destructive imaging (if interface is alive)
   Hardware imagers acquire a bit-exact clone with unstable-media profiles: variable block sizes, reverse reads, timeout/backoff, voltage/clock adjustments, and ECC-aware retries.

3. Controller & FTL handling
   Where possible we trigger controller safe/ROM/test mode, extract FTL (logical-to-physical) maps, bad-block tables, ECC/XOR/scrambler parameters, interleave/plane topology, then reconstruct a virtual image of the file system.

4. Monolith / chip-level workflow (when the USB interface is dead or damaged)

   • Monolith micro-probing: identify VCC/VSS/DQ/CLE/ALE/WE/RE/CE/RB pads; bond micro-wires for direct NAND access.

   • Chip-off: remove NAND packages, dump per die/plane/channel; apply ECC correction, de-XOR/scramble, interleave de-mix, page/block order reconstruction.

5. Logical reconstruction & carving
   Rebuild FAT/exFAT/NTFS/HFS+/APFS/EXT metadata (FAT chains, $MFT, catalogs, object maps). Content-aware carving for JPEG/RAW/HEIC, DOCX/XLSX/PDF, PST/OST, MOV/MP4/MKV, with header/footer repair and index rebuilds (moov/mdat).

6. Integrity & delivery
   SHA-256 file manifests, sample open tests, directory tree audits. Secure handover via encrypted transfer or customer-supplied media.

Top 75 USB Stick / Flash Drive Recovery Faults — with lab approach

1. Accidental deletion → clone; unallocated scan; signature-guided carving; restore timestamps where recoverable.

2. Quick format (exFAT/FAT32) → rebuild boot/FAT; reconcile directory entries; carve gaps.

3. Full format (partial overwrite) → quantify overwrite; carve residual runs; partial previews.

4. “Drive needs to be formatted” prompt → do not format; clone; repair FS boot sectors/FAT or $MFT.

5. Corrupt FAT/exFAT allocation bitmap → reconstruct chains from cluster signatures; rebuild bitmap.

6. Damaged boot sector & backup → infer BPB from heuristics; rebuild boot code/structures.

7. Lost root directory → scan for directory entries; graft orphans; EXIF/time-based reparenting.

8. Cross-linked clusters → normalise chains; carve conflicting segments to separate files.

9. NTFS shows RAW → $Boot/$MFT/$Bitmap repair; $LogFile replay; orphan recovery.

10. Hidden by malware (shortcut virus) → restore attributes on the clone; copy real content; AV scan.

11. Controller failure (no enumeration) → force ROM/test mode; if not possible → chip-off.
