Thankfully, in most cases, it is possible to recover files from a flash drive that needs formatting.
However, you need to follow the right order of actions, or the problem may get worse. In the next section, we will show you exactly what to do.
What Should You Do if Your USB Says It Needs to Be Formatted
When the Windows operating system shows the error message below, it indicates that it cannot correctly read/write data from/to the USB flash drive.

If we are discussing a brand-new pen drive that doesn’t have a file system, a mention that you have to “format a USB drive before use” might not be concerning.
However, the situation changes if you have been utilizing that storage device and have vital data saved on it.
Don’t worry!
Typically, you can take some quick actions as below to effectively and safely deal with the USB formatting issue.
Action 1. Do Not Format the USB Drive Yet
There are many scenarios in which the message indicating the USB drive requires formatting can pop up.
For example, an incompatible file system, file system corruption, a new USB flash drive, etc., can cause the problem.
Do NOT format it yet!
In all situations, formatting should be considered a last option, since it will delete all data on the drive.
Action 2. Recover & Save Your Files
Is it possible to recover files from a USB flash drive that needs to be formatted?
Yes! You can utilize one of the best USB data recovery software to retrieve your files from the pen drive that prompts for formatting.
When a USB flash drive says it needs to be formatted, it may be due to a corrupted or unsupported file system in the current operating system.
Therefore, the best app to deal with such a data recovery situation should:
- Be capable of retrieving data from corrupted file systems.
- Support all commonly used file systems across major operating systems.
- Recognize and recover files from storage devices that seem unformatted or in RAW format.
- Be user-friendly and have a fast recovery engine to ensure you can extract your files promptly.
Action 3. Find the Cause of the USB Formatting Problem
What causes your flash drive to suddenly indicate that it requires formatting?
There are several factors that may lead to the unformatted error, and it’s important to understand these causes so you can be cautious and avoid this issue with your USB flash drive in the future:
- Incompatible File System: If your USB drive is formatted with EXT3/4 or another file system that Windows doesn’t recognize, Windows will prompt you to format the drive.
- File System Damage: The file system (e.g., FAT32, NTFS, exFAT) on the USB drive may become damaged due to unsafe ejection, power interruptions, or crashes during file transfers.
- Viruses and Malware Infection: USB drives are particularly vulnerable to virus attacks when connected to unsecured devices or used for storing risky files. If a USB drive is infected by a virus, Windows may restrict access to protect your system.
- USB Hardware Malfunctions: Sometimes, hardware malfunctions with the USB drive can lead Windows to recommend formatting. This might be caused by a malfunctioning USB port, a broken USB cable, or issues with the drive itself.
- Bad Sectors: Bad sectors can lead to subpar performance of the USB flash drive and prevent Windows from reaching the data saved on these problematic sectors.
- Physical Damage: A USB drive that has sustained physical damage will cease to function, making repairs significantly more challenging.
- A Brand-new USB: If the USB drive is brand new, it may not have a file system yet. In such situations, Windows will prompt you to format the drive before it can be utilized.
Action 4. Fix the USB Formatting Problem
Once you have secured your data from your USB flash drive, you can move on to repairing it.
Ideally, you should be able to resolve any logical file system errors without needing to format.
Therefore, start by using the Windows Error Checking tool and CHKDSK in Command Prompt to correct file system issues. Additionally, changing the drive letter may potentially fix the hardware conflict.
If these methods fail, formatting the device may be necessary. We offer four ways for you to format your USB effectively and safely.
