How to recover data from a corrupted flash drive on Windows PC?

I'm in need of some urgent help. My USB flash drive has suddenly become corrupted, and I can't access any of the files on it. I'm using a Windows 10 PC, and every time I try to open the drive, I either get an error message saying the drive needs to be formatted, or it just doesn't show any of my files.

I have some important documents and photos on the drive that I really need to recover. I haven't formatted the drive yet, as I know this could lead to permanent data loss. Can anyone guide me on how to recover data from a corrupted flash drive on Windows PC? I've heard there might be some software tools or methods that can help, but I'm not sure where to start.

This is a very common and often frustrating situation. Now, you should cancel the format. How to recover data from pen drive without formatting? What happens when it shows the error message: You need to format the disk in drive (letter): before you can use it? Don’t worry, you will find the causes behind the problems and find effective solutions to fix them quickly.

Your Pen Drive Needs to Be Formatted

What Happens When the Pen Drive Needs to Be Formatted?

How to retrieve data from a pen drive before formatting? You have to learn what happens when the pen drive needs to be formatted. When you get the error, it means that the operating system can detect the physical drive (show it in Disk Management) but cannot read or understand the file system structure on it (show RAW or Unallocated).

In order for your computer to be able to read data from your USB drive, the drive must be formatted with a file system supported by your operating system. For example:

  • Windows: FAT, FAT32, exFAT, NTFS, and Microsoft’s new ReFS.
  • MacOS: HFS+, APFS, exFAT, and FAT32, but it can only read NTFS.
  • Linux: Although it supports a wide range of file systems, the most widely used ones are the FAT, XFS, Btrfs, and Ext families.

If your pendrive has a faulty file system, is formatted with a file system that is incompatible with the operating system you are using, or has no file system at all, you might encounter a situation that requires you to format your pendrive.

In a nutshell, the error shows a problem with accessing the data, and the files themselves are usually still on the drive. They remain inaccessible only because the system cannot navigate the drive’s file structure.

Why Pen Drive Need to Be Formatted?

The "need to format" error rarely occurs out of the blue. It's usually a symptom of an underlying problem:

Improper Ejection: This is the #1 cause. Unplugging the pen drive without using the "Safely Remove Hardware" option can interrupt a read/write process, which causes the format situation.
File System Corruption: Viruses, bad sectors on the drive, or sudden power outages while the drive is in use can corrupt the file system table (like the drive's "table of contents").
Hardware Failure: Flash drives have a finite lifespan based on write cycles. The memory chips or controller can eventually fail, making the data unreadable.
Incompatible File System: If the drive was formatted on a different operating system (e.g., using a macOS-specific format on a Windows PC), Windows might not recognize it natively and will ask to format it to a compatible format like NTFS or FAT32.

Now, let’s get started to troubleshoot the problem pen drive one by one.

Way 1. Try Another USB Port or Computer

Try the USB drive in another slot on the PC, then check if it can be detected. If it can be detected, you can access these files and move them to a safe location.

If that didn't work, then try another PC, preferably with a different operating system (even an older Windows 7 PC might open it). Now, you might access these files on the pen drive. However, if it’s still not working, you can try to recover files with professional data recovery software or the built-in command.

FAQs on USB Data Recovery

What does it mean when my pen drive says it needs to be formatted?

It means your computer can't read the drive's index (file system). The files are likely still there, but corrupted. Windows suggests formatting to fix this, but that will erase your data. This is why learning recovery methods is key.

Can I recover data without software?

Sometimes. You can try Windows' built-in Command Prompt tool (CHKDSK) or restore from a backup if you have one. But for most serious problems, recovery software is the easiest and most effective solution.

Can I get my data back after formatting?

Yes, but it's harder. Formatting erases the index, but the files remain until overwritten. Using recovery software right away gives you the best chance. Stop using the drive immediately after the mistake.

Is free recovery software safe?

Tools from well-known companies are generally safe. Always download them from the official website to avoid viruses. This software is designed to only read your drive, not damage it further.

How do I know if my USB is physically broken?

Look for obvious damage like a cracked connector or bent pins. If the drive is hot, makes strange noises, or isn't detected by any computer, it's likely a hardware problem. This usually requires professional repair.

On The Bottom Line

How to recover files from a flash drive that needs to be formatted for free? You should have mastered how to fix it and recovered files from the pen drive before formatting. Besides, it’s important to back up your files on the pen drive or any other device.
