It works best when the USB drive still has a recognizable file system. Here is how to run CHKDSK:<\/span><\/p>\n<p><b>Step 1.<\/b><span style=\"font-weight: 400;\"> Insert the corrupted USB drive into your computer.<\/span><\/p>\n<p><b>Step 2. <\/b><span style=\"font-weight: 400;\">Press Windows + S, type cmd in the search box.

Reinstall the USB Driver<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A corrupted or outdated USB driver can prevent Windows from reading a USB drive correctly. Reinstalling the driver forces Windows to reconnect. Follow these steps to reinstall the USB driver:<\/span><\/p>\n<p><b>Step 1.<\/b><span style=\"font-weight: 400;\"> Press Windows + X and select Device Manager, and expand Universal Serial Bus controllers.<\/span><\/p>\n<p><b>Step 2.<\/b><span style=\"font-weight: 400;\"> Locate the USB Mass Storage Device. If you are unsure which one corresponds to your flash drive, unplug the USB and plug it back in, watch which device disappears and reappears.<\/span><\/p>\n<p><b>Step 3.<\/b><span style=\"font-weight: 400;\"> Right-click the USB Mass Storage Device and select Uninstall device.

Repair Corrupted USB Flash Drive with Windows Security<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If malware is present, a USB drive can become unreliable or unreadable. Scanning the drive is essential before attempting further repairs. Windows Security allows you to scan the USB flash drive:<\/span><\/p>\n<p><b>Step 1.<\/b><span style=\"font-weight: 400;\"> Open the Start menu and search for &#8220;Windows Security.&#8221;<\/span><\/p>\n<p><b>Step 2.<\/b><span style=\"font-weight: 400;\"> Launch the Windows Security app &gt; Go to Virus &amp; threat protection &gt; Choose Scan options.<\/span><\/p>\n<p><b>Step 3. <\/b><span style=\"font-weight: 400;\">Select the Custom scan option and click Scan now.<\/span><\/p>\n<p><b>Step 4.<\/b><span style=\"font-weight: 400;\"> Select the corrupted USB flash drive and click Select Folder. Wait for the scan to finish.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Fix 7. Assign a Drive Letter to the USB Drive<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If the USB drive does not appear in File Explorer but is visible in Disk Management, it may not have a drive letter assigned. You can fix this error by assigning a drive letter to the USB flash drive:<\/span><\/p>\n<p><b>Step 1.<\/b><span style=\"font-weight: 400;\"> Press Windows + X and select Disk Management, and locate your USB drive.<\/span><\/p>\n<p><b>Step 2. <\/b><span style=\"font-weight: 400;\">Right-click the USB partition and choose Change Drive Letter and Paths. Click Add (or Change if a letter already exists) to assign an unused drive letter and click OK.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-38\" src=\"https:\/\/formatusb.com\/blog\/wp-content\/uploads\/2026\/03\/change-drive-letter-path.png\" alt=\"\" width=\"1000\" height=\"767\" srcset=\"https:\/\/formatusb.com\/blog\/wp-content\/uploads\/2026\/03\/change-drive-letter-path.png 1000w, https:\/\/formatusb.com\/blog\/wp-content\/uploads\/2026\/03\/change-drive-letter-path-300x230.png 300w, https:\/\/formatusb.com\/blog\/wp-content\/uploads\/2026\/03\/change-drive-letter-path-768x589.png 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h2><span style=\"font-weight: 400;\">If your USB drive has sustained physical damage, attempting to repair it yourself may be futile. In such cases, if the data on the USB drive is critically important, the best course of action is to consult a professional data recovery service.<\/span><\/h2>\n<h2><span style=\"font-weight: 400;\">How to Format a Corrupted USB Drive <\/span><span style=\"font-weight: 400;\">(<\/span><span style=\"font-weight: 400;\">When Repair Fails)<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Before formatting, note that this is a final reset option. Once formatted, existing files on the USB device are erased. Make sure you have a backup in advance, or try a data recovery service first.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Method 1. Use EaseUS Partition Master<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">EaseUS Partition Master provides a safer formatting workflow with preview and confirmation features. Without typing any command lines, you can easily format the corrupted USB flash drive.<\/span><\/p>\n<p><b>Step 1. <\/b><span style=\"font-weight: 400;\">Launch EaseUS Partition Master and identify your USB drive carefully by size and label.<\/span><\/p>\n<p><b>Step 2. <\/b><span style=\"font-weight: 400;\">Right-click the USB partition and select Format.

Click Execute the Task and Apply to start formatting.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Method 2. Use File Explorer<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">File Explorer offers a quick formatting option suitable for simple cases. While convenient, it offers limited control and no preview, so users should verify the correct drive before proceeding.<\/span><\/p>\n<p><b>Step 1. <\/b><span style=\"font-weight: 400;\">Open File Explorer and right-click the USB drive and select Format.<\/span><\/p>\n<p><b>Step 2. <\/b><span style=\"font-weight: 400;\">Choose a file system. Uncheck Quick Format to enable a deeper scan (takes longer).<\/span><\/p>\n<p><b>Step 3.<\/b><span style=\"font-weight: 400;\"> Click Start and confirm the warning message. Wait for formatting to complete.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Method 3. Format the USB Drive Using Command Prompt (DiskPart)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">DiskPart is a powerful disk management tool, but it permanently erases data and leaves no room for mistakes. Follow the steps below carefully to format the USB with Diskpart commands:<\/span><\/p>\n<p><b>Step 1.<\/b><span style=\"font-weight: 400;\"> Press WIN + R, type cmd in the Run box, and press Ctrl + Shift + Enter to open Command Prompt as administrator.<\/span><\/p>\n<p><b>Step 2.<\/b><span style=\"font-weight: 400;\"> Type diskpart and press Enter.

In many cases, the damage is limited to the file system and can be repaired if handled carefully. By following a low-risk repair sequence and avoiding premature formatting, you significantly improve your chances of restoring both the USB drive and its data.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">FAQs About How to Fix a Corrupted USB<\/span><\/h2>\n<ol>\n<li><b> Can a corrupted USB drive be fixed without formatting?<\/b><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">\u00a0Yes.
