Yes — most dead and undetected USB flash drives are recoverable, including drives with snapped connectors, failed controllers, or physical damage. We read the NAND directly via chip-off and monolith recovery when needed. Diagnosis is free; you approve the fixed quote before any work begins. Don't keep re-plugging it, and don't format it.
Only copy on a dead USB drive? It's usually recoverable.
USB flash drives fail more often than people expect — they're small, physically abused, and often hold the only copy of important files. A drive that isn't detected, asks to be formatted, or has a snapped connector hasn't necessarily lost its data: the NAND flash chips inside usually still hold everything.
CBL recovers USB drives at every level — from logical corruption to controller failure, snapped connectors and monolithic drives where the entire drive is a single sealed chip. When a drive won't cooperate, we read the raw NAND directly and rebuild the data.
Stop re-plugging it and don't format it. Repeated attempts can stress a failing controller, and formatting overwrites the file structure. Then book a free diagnosis.
Why USB flash drives fail
What NOT to do with a failing USB drive
Our USB recovery process
Free diagnosis
We identify the fault — connector, controller, NAND or logical — and confirm recoverability. No cost, no obligation.
Repair or bypass
For snapped connectors we repair the joint; for controller failure we attempt access, or proceed to chip-off.
Chip-off / monolith (if needed)
We desolder the NAND (or expose the monolith's contact points) and read it directly, then reconstruct the data accounting for wear-levelling, XOR and ECC.
Reconstruct & extract
We rebuild the file system and extract your files, then provide a list to verify.
Verify & return
Verified data returned on fresh media.

What we can recover — USB scenarios
| Scenario | Method | Typical outcome |
|---|---|---|
| Not detected / controller failure | Access or chip-off | High |
| Snapped / broken connector | Connector repair | High |
| Corrupt / RAW / "format disk" | Logical reconstruction | High |
| Monolithic USB drive | Monolith contact / chip-off | Case-by-case |
| Severe physical / NAND damage | Assessed individually | Reduced |

How much does USB recovery cost?
| Case type | Examples | Indicative range (SGD) |
|---|---|---|
| Logical | Corruption, RAW, deleted files | $150 – $500 |
| Connector / controller | Snapped plug, not detected | $200 – $600 |
| Chip-off / monolith | Dead drive, physical damage | $200 – $600 |

DIY: when it's safe vs when to stop
Safe to try yourself: if the drive is still detected and just has deleted files or minor corruption — and the files aren't your only copy — reputable recovery software is reasonable. Stop and call us if: the drive isn't detected, the connector is broken, it asks to be formatted, or the files are irreplaceable. See DIY vs professional recovery.

Snapped USB — final-year project
The USB plug snapped off inside a laptop port. We repaired the connector joints, accessed the drive and recovered the project files.
✓ 100% recoveredNot-detected monolith drive
A monolithic USB stick stopped being detected. We exposed the contact points, read the NAND directly and rebuilt the data.
✓ Files recovered"You need to format this disk"
A USB drive showed as RAW after unsafe removal. We reconstructed the file system without formatting and restored the photos.

The bottom line
A dead USB drive rarely means dead data — the NAND usually survives. Stop re-plugging it, don't format it, and let CBL take a look. With chip-off and monolith capability, free diagnosis, there's no risk in finding out.
