How to format a USB drive without losing data? You can find two cases and two solutions in this post.
USB drives, also known as flash drives or thumb drives, have become an integral part of our digital lives. These portable storage devices are commonly used for transferring, storing, and backing up data. However, there may come a time when you need to format a USB drive, either to optimize its performance or resolve issues.
The concern for many users is whether formatting a USB drive will result in data loss. In this article, we’ll explore the ins and outs of USB drives, why formatting may be necessary, and how to format a USB drive without losing data.
Why Do You Need to Format a USB Drive
There are several reasons why you might need to format a USB drive:
File System Compatibility: Formatting is a critical process that guarantees the optimal functionality of the USB drive. It can ensure its adherence to a compatible file system tailored to your operating system, encompassing well-recognized formats like FAT32, exFAT, or NTFS.
Corrupted File System: In the unfortunate event that the file system on the USB drive undergoes corruption, the remedial action of formatting becomes imperative, as it possesses the capability to not only effectively repair the corrupted file system but also serves as a preemptive measure, significantly minimizing the risk of potential data errors that might otherwise ensue from the compromised integrity of the file system.
Virus or Malware Removal: The process of formatting stands as a highly effective and strategic method to systematically eradicate and expunge any viruses or malware that may have insidiously infiltrated and compromised the integrity of the USB drive, providing a comprehensive solution to ensure the drive’s restoration to a pristine and secure state, free from any potential threats that could adversely impact its functionality or compromise the safety of the stored data.
Optimizing Performance: As the passage of time unfolds, it is common for a USB drive to gradually accumulate an array of superfluous files or experience the fragmentation of data, a phenomenon that can inevitably contribute to a decline in overall performance. In response to this natural progression, the deliberate act of formatting emerges as a strategic and proactive solution, serving to optimize the performance of the USB drive comprehensively. By initiating the formatting process, users can effectively reset the drive, systematically eliminating the accumulation of unnecessary files and rectifying data fragmentation, thereby restoring the USB drive to an optimal state and enhancing its efficiency throughout its usage.
Does Formatting a USB Drive Wipe It
Formatting a data storage drive including the USB drive has two options:
Quick Format
When you perform a quick format on a USB drive, the primary goal is to swiftly prepare the storage device for use without undergoing the more time-consuming process of a full format.
However, it’s important to note that a quick format does not entirely wipe the USB drive. Instead, it erases the file allocation table, making it appear as though the drive is empty and ready for new data. The actual data remains on the drive and could potentially be recovered using specialized tools.
Therefore, while a quick format is expedient, users should exercise caution and consider a full format if the goal is to securely wipe all existing data from the USB drive.
Full Format
In contrast, a full format is a more thorough and time-consuming process that not only erases the file allocation table but also scans the entire USB drive for errors and marks bad sectors.
Importantly, a full format performs a comprehensive wipe of the data on the drive, making it a preferred choice when the intention is to ensure that no remnants of previous data are left behind. This method provides a higher level of data security, especially when you want to repurpose the USB drive or hand it over to someone else.
Keep in mind that a full format takes more time than a quick format, but it offers a more complete and secure data erasure solution.
Is It Possible to Format a USB without Deleting Everything?
Both quick format and full format will remove all files from the USB drive. The key distinction lies in the recoverability of files: after a quick format, files are still recoverable, whereas a full format ensures files are wiped and unrecoverable.
Well then, is it possible to format a USB drive without data loss?
Theoretically, it’s not possible, but you can use some means to back up the data or restore the data to a safe place before formatting.
Here are two cases:
- Format a problematic USB drive without losing data.
- Format a normally working USB drive without losing data.
The following content will focus on these two situations.
Case 1. Formatting a Problematic USB Drive without Data Loss

Step 1. Connect the USB drive to the computer with MiniTool Power Data Recovery installed.

If there is more than 1 partition on the USB drive, you can switch to Devices and select the whole USB drive to scan. Here, we scan the entire USB drive.
Step 3. After scanning, this software will show you the scan results with different paths. You can open the paths to find the needed files, like documents, photos, videos, audio files, emails, and more.
Choose the files you want to recover, click the Save button, and then select a suitable location to save files. The destination location should not be the original USB drive because it has not been repaired.
If you want to use this software to recover more than 1GB of files from the USB drive, you need to upgrade to a full edition. You can go to the MiniTool Power Data Recovery License Comparison page to select the most suitable license.
Move 2. Format the USB Drive to Normal

Here are 3 commonly used ways to help you format a USB drive:
- Using the Format Partition feature of MiniTool Partition Wizard.
- Format the USB drive in Disk Management.
- Format the USB drive using Diskpart.
You can select a way based on your situation.

Option 1: Copy your important files to another location, such as your computer’s hard drive or cloud storage.
Option 2: You can transfer files from the USB drive to another storage device. Once your data is safely stored elsewhere, proceed with formatting.
