DATA RECOVERY
USB Flash Drive Data Recovery
Learn how to effectively recover data from a USB flash drive using StrongRecovery. Our software allows you to quickly restore lost photos, documents and files from formatted, damaged or unrecognised USB drives and flash memory cards.
Losing data from a USB flash drive can be frustrating and stressful, especially when the files involved are important or irreplaceable. Fortunately, there are effective ways to recover them. This article walks you through the recovery process step by step, explains which tools work best, and provides practical tips to help you avoid data loss in the future.
Most Common Causes of Data Loss on USB Flash Drives
Accidental formatting: Do not save any new files to the drive. Every byte of new data reduces the chance of a successful recovery.
"Drive not formatted" error: This is a logical file system error, not physical damage. StrongRecovery is designed to handle exactly these situations and can access the underlying data even when Windows cannot.

How to Recover Data from a USB Flash Drive in 3 Steps
Step 1
Launch StrongRecovery and select the USB flash drive from the drive list. If the drive's partition has been lost and it does not appear with an assigned drive letter or file system, follow the instructions for partition recovery.
Step 2
Once the drive is selected, StrongRecovery begins its analysis immediately. While the scan is in progress, you can already browse the reconstructed directory tree and start recovering files you need. You can also switch to thumbnail view for photos (menu → View or press F12):
Step 3
Select the files and folders you want to restore and click "Recover" from the main menu or right-click context menu. You will then be asked to choose a destination folder. Always save recovered files to a different drive – never back to the source USB drive, as doing so risks overwriting the very data you are trying to recover.
StrongRecovery also performs a DEEP SCAN of the USB drive, searching for raw file signatures (RAW files +). If the scan has completed or a satisfying number of RAW files has been found (photos or other media), you can begin recovering them immediately. Raw file detection works independently of the file system by identifying file headers, which means files can be recovered even when file system metadata – such as allocation data, file names, dates and attributes – has been lost or corrupted.

Why StrongRecovery Is the Best Choice for USB Flash Drive Recovery
Recovers data in the most common real-world scenarios:
After accidental deletion
After formatting the drive
After logical damage (corrupted file system, RAW drive)
Uses advanced recovery algorithms at both the file system level and the raw data level via deep scanning (DEEP SCAN)
Supports photo thumbnail preview (including RAW camera formats), video preview and HEX view
Built-in search lets you quickly locate exactly the files you need among thousands of recovered items
Can also extract embedded thumbnail images from within photo files, giving you an additional chance to recover a usable version
The deep scan engine covers an exceptionally wide range of file formats typically found on USB drives – photos, videos, documents, archives and project files. The software was specifically enhanced to handle the variety of content users carry on flash drives
Proper VAT invoicing: StrongRecovery is developed in Poland. For businesses and institutions purchasing internationally, we issue standard invoices and can accommodate split Buyer/Recipient billing as required for institutional procurement.
Warning: The chkdsk Trap
Many users instinctively run the built-in Windows tool chkdsk when their USB drive starts misbehaving. This is one of the worst things you can do before attempting data recovery.
"I remember a case where a user brought me a USB drive after attempting a self-repair. Following advice found online, she ran a disk check. Instead of saving her photos, chkdsk identified the damaged file fragments as file system errors and 'fixed' them by deleting them. What could have been a five-minute recovery job turned into a painstaking fight for every byte – the system had already overwritten the critical metadata needed to locate the files."
— Maciej Drobiński, author of StrongRecovery
Why chkdsk is dangerous before recovery
It cleans up, it does not recover: Its goal is file system consistency, not the safety of your photos. If a file gets in the way, chkdsk will simply remove it.
It writes to the drive: Repairing errors involves writing data to the USB drive, which can permanently destroy remnants of deleted files.
A false sense of a free fix: Some services recommend this approach knowing that once chkdsk fails, you will be left with no choice but to send the drive to an expensive data recovery lab.
The golden rule: Always use StrongRecovery first (it operates in read-only mode), save recovered files to a different drive, and only then consider repairing the USB drive.
FAQ – Frequently Asked Questions
1. Can I recover data from a formatted USB flash drive?
Yes. StrongRecovery handles this scenario reliably and can recover all or most of your files from a formatted USB drive, provided the data has not yet been overwritten by new content.
2. What should I do when Windows asks me to format my USB drive?
Do not format it. Launch StrongRecovery and select the drive from the list. For more details, see the guide on RAW drive data recovery.
3. How much does USB drive data recovery cost with StrongRecovery?
To get started? Nothing at all. The free version recovers up to 50 files with a combined size of up to 5 GB, which covers the entire contents of many USB drives. For larger amounts of data, a license is available to suit your needs.
4. Is it safe to run chkdsk before recovering data?
No. chkdsk can permanently delete files and overwrite data on the drive during its repair process. Always use StrongRecovery in read-only mode first to secure your files on a separate drive, and only then consider running any repair tools.
5. What file types can StrongRecovery recover from a USB flash drive?
StrongRecovery recovers photos (JPG, RAW, CR2, CR3, NEF, ARW), videos (MP4, AVI, MOV, MTS, AVCHD), documents (PDF, DOCX, XLSX), archives and many other formats. The deep scan engine supports an exceptionally wide range of file types commonly carried on USB flash drives.
