USB Flash Drive Data Recovery Services
Thumb Drives, USB Sticks, and Portable Flash Storage
Your USB flash drive is not recognized, shows as RAW, or asks to be formatted? We recover data from controller failures, NAND corruption, and physically damaged flash drives. Our Austin lab handles everything from simple file recovery to complex chip-off procedures.
No Data, No Charge. USB recovery: $200-$1,800 depending on failure type.
USB Flash Drive Failures We Recover
USB flash drives fail differently than hard drives. They have no moving parts, but the controller chips and NAND flash memory can still fail in multiple ways.
Controller Failures
The controller chip manages communication between your computer and the NAND flash memory. When it fails, the drive may not be recognized at all, or show as 0 bytes capacity.
Common controllers: Phison, Silicon Motion (SMI), JMicron, Alcor, Innostor
Recovery approach: Controller repair, firmware reload, or direct NAND chip reading if controller is dead.
NAND Flash Corruption
NAND flash memory wears out over time (limited write cycles). Cheap flash drives use lower-quality NAND that degrades faster, leading to bad blocks and data loss.
Symptoms: Files corrupted, drive becomes read-only, random data errors, shrinking capacity.
Recovery approach: Raw NAND dump, error correction, file system reconstruction.
Physical Damage
USB flash drives are vulnerable to physical damage: bent or broken connectors, cracked PCBs, water damage, or drives that have been stepped on or run over.
Symptoms: Visible damage, intermittent connection, drive not recognized.
Recovery approach: Connector repair, PCB jumper wires, or chip-off if PCB is destroyed.
File System Issues
If the drive is still recognized but shows as RAW, asks to format, or files are inaccessible, the file system metadata is damaged but data may be intact.
Causes: Improper ejection, power loss during write, malware, accidental format.
Recovery approach: File system repair, partition table rebuild, file carving from raw data.
Monolith USB Flash Drive Recovery
Many modern USB flash drives use a "monolith" design where the controller and NAND flash are encapsulated together in a single chip package. These drives are smaller and cheaper but much harder to recover when the controller fails.
The challenge: There are no separate NAND chips to remove and read directly. Recovery requires micro-soldering wires directly to the chip die to access the NAND memory.
Our approach: We have specialized equipment and adapters for monolith flash recovery. While more expensive than standard chip-off, we can recover data from many monolith drives that other labs cannot handle.
Monolith vs Standard Flash Drive
| Feature | Standard | Monolith |
|---|---|---|
| NAND Chips | Separate | Integrated |
| Chip-off possible | Yes | Limited |
| Recovery difficulty | Moderate | High |
| Cost range | $400-$1,200 | $800-$1,800 |
How We Recover Data from USB Flash Drives
Every USB flash drive recovery starts with a free evaluation. We identify the failure type before quoting a price, so you know the cost before any billable work begins.
- 1
Visual and electrical inspection
We check for physical damage: broken connectors, cracked PCBs, burn marks, or bent pins. If the connector is damaged, we assess whether it can be re-soldered or if direct NAND access is needed.
- 2
Controller and firmware diagnosis
If the drive powers on but is not recognized, we identify the controller chip (Phison, Silicon Motion, Alcor, etc.) and attempt firmware-level repair using manufacturer-specific tools.
- 3
Imaging or chip-off
For working controllers, we create a sector-by-sector image. For dead controllers or destroyed PCBs, we desolder the NAND chips, read them in a programmer, and reconstruct the data using the controller's ECC algorithm and block mapping.
- 4
File system reconstruction and verification
We rebuild the file system from the raw image, verify file integrity, and present a file listing. You approve the results before we transfer your data to a new drive.

USB Flash Drive Recovery Pricing
USB flash drive recovery costs depend on the type of failure. Simple file system issues are cheapest; controller failures and chip-off procedures cost more.
| Failure Type | Price Range | What's Involved |
|---|---|---|
| File System / Logical Issues | $200-$400 | Drive recognized, partition repair, deleted file recovery, RAW file system. |
| Controller Failure (Standard) | $400-$1,000 | Drive not recognized, firmware reload or NAND chip-off recovery. |
| Physical Damage / Connector Repair | $400-$800 | Broken USB connector, cracked PCB, micro-soldering required. |
| NAND Chip-Off Recovery | $800-$1,500 | Remove NAND chips, read directly, reconstruct data from raw dump. |
| Monolith Drive Recovery | $800-$1,800 | Integrated controller/NAND, requires micro-wire soldering to access memory. |
We provide a firm quote after evaluating your drive. No surprises. If it turns out to be simpler than expected, you pay the lower price.
Hard Drive Data Recovery Standards & Verification

Media Coverage
Our repair work has been covered by The Wall Street Journal and Business Insider, with CBC News reporting on our pricing transparency. Louis Rossmann has testified in Right to Repair hearings in multiple states and founded the Repair Preservation Group.
Aligned Incentives
Our "No Data, No Charge" policy means we assume the risk of the recovery attempt, not the client.
Technical Oversight
Louis Rossmann
Louis Rossmann's well trained staff review our lab protocols to ensure technical accuracy and honest service. Since 2008, his focus has been on clear technical communication and accurate diagnostics rather than sales-driven explanations.
We believe in proving standards rather than just stating them. We use TSI P-Trak instrumentation to verify that clean-air benchmarks are met before any drive is opened.

Avoid These Mistakes
- ✗Do not format the drive. When Windows asks to format, clicking Yes overwrites critical data structures.
- ✗Do not keep plugging it in repeatedly. If the drive has electrical damage, each connection can cause more damage.
- ✗Do not try to repair the connector yourself. USB connectors require precision soldering. Poor repairs can destroy traces.
- ✗Do not use low-quality recovery software. Some tools make aggressive write attempts that can corrupt NAND further.
Safe Steps to Take
- ✓Stop using the drive. The less you use it, the better your recovery chances.
- ✓Note what happened. When did it fail? What were you doing? Any error messages? This helps diagnosis.
- ✓Check if it is recognized. Open Disk Management (Win+X) and see if the drive appears, even as unknown.
- ✓Get a professional evaluation. We diagnose for free and tell you exactly what is wrong before any billable work.
USB Flash Drive Recovery: Common Questions
Can data be recovered from a USB flash drive?
Yes. USB flash drive data recovery is possible in most cases. Even when a flash drive is not recognized, shows as RAW, or has physical damage, the NAND flash chips containing your data are often intact. Professional recovery can access the chips directly if the controller fails.
How much does USB flash drive recovery cost?
USB flash drive recovery costs $200-$400 for logical/file system issues, $400-$1,000 for controller failures, and $800-$1,800 for NAND chip-off recovery (removing and reading chips directly). Monolith drives with no removable chips may cost more due to micro-soldering work required.
Why is my USB flash drive not recognized?
Common causes include controller chip failure, damaged USB connector, NAND flash corruption, firmware bugs, or file system damage. If the drive is not recognized at all, it usually indicates controller or physical damage rather than simple file system issues.
Can you recover data from a broken USB stick?
Yes. Physical damage like broken connectors, bent plugs, or snapped PCBs can often be repaired or bypassed. In severe cases, we remove the NAND flash chips and read them directly. The key factor is whether the NAND chips themselves are damaged.
How long does USB flash drive recovery take?
Simple logical recovery takes 1-3 days. Controller failures requiring chip-off take 1-2 weeks. Monolith drives requiring micro-soldering may take 2-3 weeks.
What brands of USB flash drives do you recover?
We recover data from all USB flash drive brands including SanDisk, Kingston, Samsung, PNY, Lexar, Corsair, Verbatim, and generic drives. The brand matters less than the controller chip inside.
