Lost data from a flash drive? At DataHelp we offer professional data recovery from damaged or non-functional flash drives using advanced technologies and algorithms that enable data recovery even from the most complex cases.
At DataHelp we offer top-tier services for data recovery from any type of flash memory. We have years of experience with various manufacturers, such as ADATA, Kingston, Corsair, SanDisk, Verbatim, Patriot, Transcend, Silicon Power, Samsung, Leef, EMTEC, Pitaka and others.
Flash drives can fail for many reasons, whether it's controller chip failure, memory cell damage, or file system error. We often encounter cases where the disk is mechanically damaged or needs to be formatted. In such cases, it's crucial not to make further connection attempts – each additional intervention can reduce the chances of successful data recovery.
Our technology and equipment enable data recovery even from the most complicated situations. Thanks to advanced algorithms, we can reconstruct damaged file systems and restore your files to their original state.
With our team of experts, years of experience, and state-of-the-art methods, you can be sure your data is safe. Contact us, and we'll perform diagnostics (€45 European pickup) and suggest the most suitable procedure for recovering your data.

When recovering data from flash drives, we use special tools to create images of your media, which we then work with. This process includes file system reconstruction and recovery of individual files. Unlike other types of media where mechanical damage often occurs, flash drives are less prone to mechanical failures, which simplifies and speeds up the data recovery process.
Despite the smaller capacity of some flash drives, we encounter various problems such as controller chip failure or memory cell damage that require expert intervention.
Additionally, maintaining the file system structure is crucial for full data reconstruction during recovery. Problems with damaged file system or mechanical connector damage can complicate data access, but thanks to advanced techniques and equipment, we can achieve high recovery success rate.
USB flash drives contain NAND flash memory chips, a controller chip, and USB interface. Construction varies by manufacturer and price category, which directly affects data recovery complexity.
Modern flash drives often use monolithic construction, where all components are integrated into one chip. This construction is more compact and durable, but data recovery is significantly more complex – requiring specialized equipment for direct access to memory cells.
Separate components on PCB board – controller chip, memory chips, USB connector. Easier data recovery – direct access to memory chips is possible.
Everything in one chip including USB connector. More complex recovery – requires special adapters and knowledge of chip internal structure.
Chip embedded in epoxy directly on the board. Often on cheap flash drives. Medium complexity recovery.
Each manufacturer uses different controller chips and memory technologies. Our laboratory has an extensive database of firmwares and tools for working with all common USB flash drive brands.
If the flash drive is not recognized, reports an error, or requests formatting, disconnect it immediately. Repeated connection attempts can cause further data or memory cell damage.
Windows often offers formatting or disk repair. Never select these options – they can irreversibly overwrite data. Also avoid common data recovery programs for hardware failures.
Send us the flash drive for diagnostics (€45 European pickup). We'll determine the type of failure (software vs. hardware), extent of damage, and chance of successful recovery. You only pay for successful data recovery.
Broken USB connector? Even in case of mechanical damage, we can recover data. We solder a new connector or access memory chips directly using specialized adapters.

Stop using the drive immediately — any new write overwrites recoverable sectors.
Keep the drive in an anti-static bag; do not bend or apply heat.
If the drive breaks physically, collect all pieces — the NAND chip can still be recovered via chip-off.
Do not format the drive when prompted by Windows — formatting wipes the partition table.
Flash drives are not typically repaired for continued use. Once a controller or NAND chip fails, the drive is at end-of-life — even if we can extract the data, the underlying hardware wear-leveling state is compromised and the drive should not be trusted for storage.
Our specialisation is data extraction. For standard USB drives we can swap the PCB or reprogram the controller. For monolithic designs (common in low-cost USB sticks) we use chip-off recovery — desoldering the NAND and reading directly with specialised equipment.
After recovery we return your data on a new verified medium. The original USB drive is typically physically destroyed or returned (at your choice) — we never return drives for continued use.
If your USB drive is intermittently recognised, shows wrong capacity, or triggers Windows errors, stop plugging it in. Every connection attempt triggers the controller to reorganise flash cells, and a failing controller can corrupt the translation table (FTL), making recovery much harder or impossible.
Do not use third-party 'repair' tools that offer low-level format or firmware reflash — these typically mark all sectors as blank, destroying the directory structure. If Windows offers to format the drive, always click Cancel.
USB flash recovery requires specialised equipment (Rusolut Visual NAND Reconstructor, PC-3000 Flash, BGA rework station) plus deep knowledge of each controller's firmware and address translation. Every manufacturer (Phison, Silicon Motion, Alcor, USBest, ChipsBank) uses proprietary internal formats that generic tools cannot interpret.
Our specialists have reconstructed data from thousands of USB drives — from standard SanDisk Cruzer drives up to monolithic chips and physically broken sticks where only the NAND fragment survived. For chip-off recovery we operate two BGA rework stations and maintain an inventory of common USB controllers for firmware transplants.
Our team has over 35 years of combined industry experience. Typical recovery success rate on USB flash: 85% for controller failures, 60–70% for monolithic chip-off, 40–50% for physically broken drives with damaged NAND.
