USB drives are common portable storage devices in daily life. Issues can inevitably arise during use, such as a message that says "You need to format the disk before you can use it" when you try to access files within. At this moment, clicking "Format Disk" will erase the data, while ignoring the error message leaves you unable to access them. It’s a dilemma, right? If you’re facing such issues, then this article is very helpful. Here, we will explore the reasons behind the issue and guide you through the whole process of how to recover files from a USB drive that needs formatting and fix the error.
This is equivalent to an error code when the USB drive's file system is corrupt or unreadable. You should know that the main function of a file system is to organize data and manage storage. When some of its critical information is corrupted, such as the partition boot sector (DBR), file allocation table (FAT), or root directory, or when it itself has a bad sector, the operating system can’t make clear the USB drive storage layout, thereby triggering this error message asking you to format it.
Simply put, the operating system tells you that it can’t recognize the current storage structure and asks you to rebuild a usable file system. Coincidentally, this can be achieved through formatting. That’s why you see the prompt when you try to open the flash drive. The reason for this situation is one of the following:
No, it will not. A file system failure or hardware damage has nothing to do with the data that is physically saved on the USB drive. The error just prevents the file system from locating and recognizing your files. It’s like tearing the table of contents of a book doesn’t mean the actual content(pages) is deleted. Conversely, formatting seems like a quick solution, but it will erase all the data. Therefore, please do not perform formatting operations and retrieve your files as soon as possible using the following methods.
Now that you have confirmed there are important files on the flash drive still, then it’s very easy to get them back. As mentioned in the previous part, the prompts to format the drive generally stem from two main causes: file system corruption/incompatibility, and USB firmware issues. For this, you can try the following two solutions one-by-one.
In most cases, the reason why your USB drive needs to be formatted is due to its file system. To recover your data from it, you'll need a powerful data recovery software program. It will bypass the corrupted file system to retrieve recoverable files, such as photos, documents, videos, and music hidden in the damaged or inaccessible sectors. This method allows you to recover files from a flash drive that needs to be formatted without repairing the file system, thereby preserving the integrity of the data stored.
Here, we recommend you try iBeesoft Free Data Recovery. Why? It not only offers two scanning modes but can also gather and reassemble fragmented files on USB drives to maximize the data recovery success rate. Additionally, iBeesoft Free Data Recovery has the following powerful features:
When the problem lies with the firmware, using software to recover files from the flash drive that needs to be formatted won't work. In this case, seeking professional data recovery services is your last option. Although it can be expensive and time-consuming, they can disassemble and repair the physical components of your flash drive. By doing so, they can access the storage chip or fix hardware-level faults directly to retrieve your important data. If you think it is worth, simply search for a service provider in your area.
Once you have successfully recovered all the files from the USB drive that needs formatting, the final step is to fix the drive itself.
When faced with the prompt querying whether the flash drive needs to be formatted, many people would like to try CHKDSK to fix the error first. In some cases, it can indeed repair a corrupted file system and address bad sectors that interfere with normal read/write operations. With a bit of good luck, the following command might restore the USB drive to its normal working state.
CHKDSK will begin scanning for and attempting to repair errors on the USB drive. How long it will take depends on the drive's capacity and the severity of the issues. If you encounter the message "CHKDSK is not available for RAW drives," the best action is to use Method 3 in this section to format the USB drive and rebuild its file system. Before that, be sure to recover your data first.
There are many disk management tools on the Internet, such as iBeesoft Disk Partition Wizard, which offers more comprehensive features than CHKDSK to fix various hard drive errors, including the issue where a flash drive needs to be formatted. If the aforementioned methods do not work, a professional disk management tool may help resolve the problem.

As you can see, it can be confusing and disturbing to see a prompt to format your USB drive; do not click "Format disk" to resolve the error hastily.
