Professional USB Flash Drive Data Recovery Services

USB Flash Drive Brands We Recover Every Week

eProvided has recovered data from every major USB flash drive and thumb drive brand on the market for more than two decades. The most common brands and SKUs we see in the recovery lab include Kingston DataTraveler, SanDisk Cruzer, SanDisk Cruzer Micro, Lexar JumpDrive, Lexar Media, PNY Attaché, Patriot Supersonic, Corsair Flash Voyager, Verbatim Store 'n' Go, Toshiba TransMemory, Memorex TravelDrive, Samsung BAR Plus, Mushkin Atom, ADATA UV Series, HP USB drives, Transcend JetFlash, Ridata thumb drives, and generic OEM thumb drives. We see the same physical, logical, and electrical failure patterns across all of them — controller damage, NAND degradation, snapped USB connectors, water damage, and corrupted file systems — and our recovery process is brand-agnostic.

Whether you have a $10 promotional giveaway thumb drive or a high-end Corsair Survivor with case-grade construction, the underlying NAND chips and controllers come from a small number of fabs. eProvided's chip-off and controller-replacement workflows handle the entire spectrum. Send us your drive — we'll tell you in the free evaluation what the failure mode is and quote you before any work begins.

USB Versions and Connectors We Recover

USB flash drives have evolved through every interface generation since the late 1990s, and eProvided recovers data from all of them. Common formats we see in the lab include USB 2.0 Type-A drives (the standard rectangular connector), USB 3.0 / 3.1 / 3.2 high-speed drives (typically blue or red plastic insert), USB-C drives (used by modern phones, tablets, and laptops), USB-OTG dual-connector drives (USB-A on one end, micro-USB or USB-C on the other for direct phone-to-computer transfer), and older USB 1.1 drives still circulating from corporate giveaways and consumer-electronics era pen drives. Connector types include full-size USB-A, micro-USB-B, mini-USB-B, and USB-C. Whatever the version, the data lives on the same NAND flash chip inside — we extract it regardless of how the connector is shaped or whether the host interface still works.

Sony Memory Stick and Other Legacy USB Flash Formats

Some USB flash formats are no longer current production but still hold valuable data. The Sony Memory Stick family — including Memory Stick PRO, Memory Stick Duo, Memory Stick PRO Duo, and Memory Stick Micro (M2) — was Sony's proprietary USB-style flash format used in Sony cameras, camcorders, the PSP, and Vaio laptops from 1998 through the mid-2010s. eProvided recovers data from Memory Sticks that have failed due to controller faults, water damage, physical breakage, or simple age-related NAND degradation. The same workflow applies to other legacy USB-format media we still see — older proprietary thumb drives from corporate giveaways, ruggedized industrial flash, and obscure brand SKUs that have long since left the market.

If you have an old Memory Stick from a Sony camera or a forgotten thumb drive in a desk drawer, the data on it is often perfectly recoverable. Don't assume legacy formats are unrecoverable — ship it to the lab for a free evaluation.

Fix Broken or Physically Damaged USB Flash Drives

"Fix" and "repair" are words USB flash drive owners type into search engines every day, and they describe a specific class of failure: physical damage that prevents the drive from being recognized at all. eProvided's lab fixes USB drives that have been snapped at the connector, crushed under furniture, run through a washing machine, dropped from a moving vehicle, cracked in half, chewed by a dog, damaged in a fire, or struck by lightning. We don't repair the casing — we extract the data. The casing and connector go in the recycling bin; the recovered files come back to you on a fresh USB drive.

Common repair-class and physical-failure scenarios we handle:

• Broken USB connector — the metal USB-A or USB-C tip has snapped off the PCB. We re-attach or bypass the connector to read the NAND.
• Cracked or split PCB — the internal circuit board is fractured. We rebuild the broken traces or perform NAND chip-off extraction.
• Burnt-out controller — the controller chip is dead from a power surge, static discharge, brown-out, or electrical spike. We swap the controller or read the NAND directly.
• Water- or salt-water-damaged drive — the drive went through a flood, pool, ocean, or laundry cycle. Do not power it on. Ship it to us; we'll dry it under controlled conditions and recover the data.
• Bent or crushed thumb drive — physical impact has deformed the casing. We open the drive, assess NAND integrity, and extract.
• Run-over by a vehicle — tire-crushed drives are common. The NAND chip itself is small enough that it usually survives even severe physical compression.
• Bitten or damaged by a pet — punctured casings and exposed PCBs from dog or rodent damage. The NAND chip is recoverable in nearly every case.
• Fire- or heat-damaged drive — we recover from drives that have survived house fires, hot car interiors, or industrial heat exposure as long as the NAND chip itself didn't melt.
• Lightning strike or power surge — an electrical event has fried the controller. NAND data is preserved on the chip and recoverable via chip-off.
• Encrypted or password-locked drive — the user has lost the password or the encryption layer is corrupted. We can extract raw NAND data and, where the encryption key is recoverable, restore plaintext files.

Chip-Off NAND Flash Recovery — Our Technical Specialty

When a USB flash drive's controller is dead but the NAND memory chip is physically intact, the only path to your data is chip-off NAND extraction. eProvided removes the flash memory component from the damaged drive and dumps RAW hexadecimal data directly from the chips using specialized programmer hardware. This bypasses the failed controller entirely. Our engineers then reconstruct the file system from the raw NAND dump using algorithmic re-interpretation of the chip's wear-leveling and ECC patterns. This is the technique that has allowed us to recover data from physically destroyed drives, fire-damaged devices, water-damaged smartphones, and crushed flash media for clients including NASA, the Department of Defense, the Pentagon, the U.S. Air Force, JPL, Boeing, and the White House since 1999. If your USB flash drive shows up as "Unknown Device" in Windows or doesn't power on at all, chip-off recovery is the next step — and it's our specialty.

If your USB flash drive is broken, damaged, dead, or unresponsive, eProvided's lab can almost always recover the data — even when the drive looks unrecoverable. Free evaluation. No Data, No Data Recovery Fee. 27+ years of brand-agnostic flash media expertise.

Thumb Drive Recovery, Pen Drive Recovery & Jump Drive Recovery

Whatever you call it — thumb drive, pen drive, jump drive, or flash stick — eProvided recovers data from every form factor in the category. Thumb drive recovery is one of our most frequent case types: these drives get snapped in laptop ports, run through washing machines, sat on, chewed by dogs, and left in car doors. The NAND chips inside survive most physical abuse; the connectors and controllers do not. Our chip-off workflow extracts data directly from the NAND even when the drive is physically unrecognizable.

Common thumb drive recovery scenarios we handle every week: broken USB-A connector, cracked PCB, controller failure from power surge, water damage, fire damage, password-locked drives, and deleted files with no backup. Pen drive repair requests almost always become recovery cases — we don’t fix the housing, we fix your access to the data. If your search brought you here looking to repair a thumb drive, you’re in the right place. We recover Kingston DataTraveler, SanDisk Cruzer, Lexar JumpDrive, PNY, Verbatim, Patriot, and any promotional giveaway drive regardless of brand. Free evaluation — no thumb drive recovery fee if we can’t get your data.

USB Drive Not Recognized? “Unknown Device” Error? We Recover the Data.

When Windows shows “USB device not recognized — One of the USB devices attached to this computer has malfunctioned” or “Unknown Device” — and the drive doesn’t appear in File Explorer, Disk Management, or Device Manager — no software tool can help. If the operating system can’t communicate with the drive, recovery software can’t either.

Mac users see the equivalent: “The disk you inserted was not readable by this computer” or the drive fails to mount in Finder entirely. These errors point to controller failure, firmware corruption, a shorted controller chip, or a broken electrical path between the plug and the NAND — all requiring hardware-level recovery.

eProvided diagnoses and recovers data from USB drives showing as unknown device, malfunctioned, not recognized, or completely absent from the system. We see this across every brand: SanDisk not recognized, Lexar drive not recognized, PNY USB not recognized, Kingston, Transcend, and every other manufacturer. The controller may be dead — the NAND data almost never is. Our chip-off and controller-bypass workflows read that NAND directly. If you’ve tried every port, every computer, and the drive still isn’t showing up — stop trying and ship it to us. Further connection attempts accelerate damage.

Flash Drive Repair vs. Flash Drive Data Recovery — What You Actually Need

Most people searching for “flash drive repair” or “USB repair” need data recovery, not hardware repair. There is no practical way to repair a USB flash drive’s casing, PCB, or controller so the drive works again — the economics don’t exist. What IS possible is recovering every file from that drive’s NAND chips and returning them to you on a new device.

eProvided performs USB flash drive repair in the only sense that matters: we repair your access to the data. We do this by replacing or bypassing the failed controller, re-soldering broken connectors, or extracting NAND chips directly. Terms like fix USB flash drive, fix broken flash drive, repair flash drive, flash disk repair, thumb drive repair, and pen drive repair all describe the same need — and they all lead to the same solution. Ship us the drive; we’ll return you the data.

Windows 11 & Windows 10 USB Errors We Recover Data From

Every USB failure throws a different error, and the error message tells our recovery specialists where in the drive the failure happened. If your USB drive shows any of these messages on Windows 11, Windows 10, or Mac, the data is almost always still on the NAND chips — only the path to read it is broken. We recover from every error in this list every week.

• “USB Device Not Recognized” — Windows detected electrical activity but the drive failed handshake. Controller stuck, dead, or returning corrupted ID data.
• “Unknown USB Device (Device Descriptor Request Failed)” — The drive cannot return its identity string. Almost always firmware corruption or controller failure. NAND data is intact.
• “One of the USB devices attached to this computer has malfunctioned” — Drive responded but failed enumeration. Yellow exclamation mark in Device Manager confirms it.
• Device Manager error code 43 — Windows stopped the device because it reported a problem. Underlying cause is hardware, not driver.
• “Please insert a disk into removable disk” — Drive enumerates but reports zero capacity. Phison and SMI controllers commonly enter this “boot mode” after a power-cut write.
• Mac: “The disk you inserted was not readable by this computer” — or the drive refuses to mount in Finder at all. Same hardware causes as the Windows errors above.

None of these errors can be cleared by recovery software, driver updates, or different USB ports. If the drive is invisible to the operating system, software has nothing to read. Hardware-level recovery in our specialized lab is the only path. Repeated reconnection attempts on a failing drive accelerate the damage — stop trying and ship it.

USB Drive Capacities We Recover — 8GB to 2TB and Beyond

USB flash drive recovery success does not depend on capacity. We recover data from drives of every size, from older 4GB and 8GB sticks to current 1TB and 2TB high-capacity drives. The internal architecture changes with capacity — small drives use a single NAND die, mid-tier drives stack 2-4 dies on one package, and high-capacity drives use multi-package monolithic designs — but every architecture is recoverable through chip-off NAND extraction.

• 8GB, 16GB, 32GB USB drives: Most common consumer sizes. Single-die NAND in most models. Chip-off recovery is straightforward when the controller fails.
• 64GB, 128GB USB drives: Multi-die NAND with interleaved write patterns. Recovery requires reconstructing the controller’s data layout map.
• 256GB, 512GB USB drives: High-density TLC or QLC NAND, often with hardware encryption layers. Our specialists handle the encryption bypass on standard consumer drives.
• 1TB, 2TB USB drives: Multi-package SSD-class architecture inside a USB form factor. These drives use full SSD controllers and benefit from our SSD recovery workflow applied to the USB enclosure.

If your drive’s capacity is not listed here, we still recover it. We have processed every form factor and every capacity tier sold in the US market over the past 27 years.

Photos, Videos, Documents — What We Recover From Failed USB Drives

The most common files lost on a failed USB flash drive are photos and videos — family pictures, professional shoots, irreplaceable footage. Our recovery process retrieves every file type stored on the NAND, not just specific formats:

• Photo formats: JPEG, JPG, PNG, HEIC, TIFF, BMP, GIF, plus camera RAW formats (Canon CR2/CR3, Nikon NEF, Sony ARW, Fujifilm RAF, DNG)
• Video formats: MP4, MOV, AVI, MKV, WMV, MPEG, plus professional formats (ProRes, DNxHD, R3D)
• Documents: Microsoft Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint, PDF, plain text, OpenDocument
• Other data: ZIP archives, database files, design files (PSD, AI, INDD), CAD files, source code, encrypted containers

If the NAND is intact, your files are intact. We recover every readable byte from the chips and reconstruct the file system that points to your data. Photo recovery, video recovery, and document recovery from USB flash drives are all the same hardware process under the hood — only the verification step at the end differs.

USB Stick Recovery & USB Drive Recovery — Every Connector, Every Chip Package

USB stick recovery and USB drive recovery cover the same hardware family from different angles — connector type, internal architecture, and intended use. We perform USB stick recovery on the cheap promotional stick a marketer hands out, USB drive recovery on the high-capacity professional drive a videographer relies on, and everything in between.

The internal NAND chip package determines our chip-off approach. BGA (ball grid array) packages found on most modern consumer drives use one extraction technique — the package is desoldered with hot-air rework equipment and read on a programmer that maps the ball pads to NAND signals. TSOP (thin small-outline package) packages common on older USB drives use a different method, with through-hole pin clamping. Monolithic single-die designs in budget USB sticks need a third approach — the entire memory die is exposed by grinding off the epoxy and contacted directly with test points.

Every USB drive in our lab is identified by its controller chip before we choose the recovery path: Phison, Silicon Motion (SMI), Alcor, Skymedi, Innostor, or vendor-specific. The controller dictates the data layout on the NAND, so identifying it correctly is the difference between a successful USB stick recovery and a misread of the raw data.

If your drive has stopped responding entirely, ship it for a free evaluation. If your failed device is a memory card or SD card rather than a USB stick, we also handle broken memory card recovery under the same lab process.
