reformat thumb drive on windowsDid you recently format your USB, only to realize afterward that you didn’t get a chance to back up the data stored on it? This can all happen within seconds. Once it’s done, you’re left frantically searching for a way to undo the process and get your data back.

If you’re wondering if it’s possible to unformat a thumb drive, we’ll explain the answer in this article, as well as how to get your lost data back.

Can You Unformat a USB Flash Drive?

There is no way to unformat a USB stick in the sense of reversing a format that recently took place. Once a format has taken place, the only way to unformat a USB is to format it again with a new file system or remove the file system entirely. However, it is possible to recover the data that was lost due to the formatting process. This is done using specialized data recovery software.

Before you unformat a flash drive with a new file system, you must recover the data that was lost in the initial format. While that data remains lost, it’s vulnerable to being overwritten by any new data that is written to the USB. Therefore, you don’t want to take any risks by formatting the USB again and then performing recovery.

How to Recover Files From a USB After Formatting

In some cases, formatting is necessary. Typically, Windows will insist that your USB needs to be formatted when it notices something wrong, such as corruption. If you’ve already formatted your USB that contained data, you still have a chance of recovering your lost files, as long as you performed a quick format and not a full format.

To recover the data, we recommend Disk Drill, a data recovery tool that’s designed for cases like this. It’s quick, easy to use, and offers up to 500 MB of free recovery before needing to upgrade.

Tip Description
🗃️ Choose the right file system Some devices only accept certain file systems. Typically, only compatible file systems will show as options, but bear this in mind if using third-party tools.
⏩ Always quick format Only in rare instances should you perform a full format. It’s best to go with a quick format because it’s fast and gives you a chance to recover your data if something goes wrong.
⏏️ Don’t remove the drive Never remove the storage device during a format. Doing so can cause the file system to become corrupted, leading to further complications.
