Recovery from USB flash drives with broken connectors, damaged circuit boards, failed controllers, unreadable NAND memory or corrupted file systems.
Stop using the USB drive
Do not repeatedly bend or reconnect a broken plug. Do not format the device when Windows or macOS asks, and do not save recovered files back to the same flash drive. If the device becomes hot, disconnect it immediately.
Common failure types
Broken connector
Cracked solder joints, torn pads and damaged USB plugs may be repairable long enough to image the storage.
Electronic or controller failure
The device may not enumerate, may show the wrong capacity, or may disconnect during reads.
NAND and logical damage
Bad memory cells, corrupted translation data, accidental formatting and damaged file systems can require controlled imaging or direct memory work.
Monolithic and standard designs
Some USB drives have separate controller and NAND packages; others combine the circuitry into a monolithic package. Recovery method, feasibility and cost depend on the exact architecture and condition. Direct NAND recovery can require reconstructing the controller’s data transformation rather than simply reading files from a chip.
Process
- Identify the drive, capacity, symptoms and most important files.
- Inspect the connector and electronics.
- Attempt controlled access without modifying the original data.
- Quote any required microsoldering, controller work or direct-memory recovery.
- Image readable content and reconstruct the file system or files to separate media.
Limitations
Overwritten files, severe NAND degradation, cracked monolithic packages, internal layer damage and encryption without the required key can prevent recovery. A physically repaired USB drive should not be trusted for continued storage.
Frequently asked questions
Can a snapped USB stick be recovered?
Often it can be assessed, but the result depends on whether the NAND package and critical connections survived.
Should I solder the connector myself?
DIY soldering can tear pads, short power rails or damage the memory. If the files matter, avoid further work.
Can you recover deleted USB files?
Potentially, if the data has not been overwritten and the device is stable enough to image. Stop using it immediately.
Send an unreadable USB drive for assessment
Tell us what happened, what device you have and which files matter most. We will provide packing instructions for a tracked mail-in case or arrange a Timaru drop-off.
Submitting an enquiry does not authorise paid recovery work. Any applicable assessment, parts, media, courier or recovery charges are explained before you approve them.
