How to fix your USB drive not showing up on Windows 11 or Windows 10

When you plug a USB drive into your Windows PC, it should automatically appear in File Explorer. If it does not, follow this exact troubleshooting hierarchy to diagnose the issue without risking your data. Diagnosing why your USB drive is not showing up If you connected a USB drive and Windows doesn't show up in the file manager, you should first check the Disk Management window. To open Disk Management on Windows 11 (or Windows 10), right-click the Start button and select "Disk Management." Examine the list of disks in the disk management window and look for your external drive. Even if it doesn't show up in File Explorer, it should appear here. Look for a disk that matches the size of your flash drive. Sometimes, it'll also be marked as Removable, but not always. In the screenshot below, we've spotted our removable drive at "Disk 7." If you see yours, move onto the next section. Check the Basics Before diving into Windows settings, verify the physical connection. Plug the drive directly into a different USB port on your computer, preferably a USB 2.0 port on the back of a desktop tower. USB 3.0 ports sometimes struggle with older controllers. Avoid USB hubs, as they often fail to supply enough power. Clean the drive's connector with a cotton swab and 90% isopropyl alcohol to remove oxidation. Test the drive on another computer. If it fails to appear in Disk Management on multiple machines, the hardware itself is likely dead. Power On the Drive, if Necessary: Some external hard drives have their own power switches or separate power cables. If you're using a larger drive, ensure it doesn't have its own power switch or power cable you need to connect. Plug It Into a Different USB Port: Try unplugging the external drive and plugging it into a different USB port on your computer. It's possible that one particular USB port on the computer is dead. Always make sure to try one on the back of your PC, too. Avoid USB Hubs: If you're plugging the USB drive into a USB hub, try plugging it directly into one of your computer's USB ports instead. It's possible the USB hub doesn't supply enough power. Try a Different Computer: Try plugging the USB drive into a different computer and see if the other computer detects it. If no computers see the drive when you connect it—even in the Disk Management window—the USB drive itself is likely dead. Hopefully, one of these will solve your problem. If not, move onto the fixes outlined below. Disable USB Selective Suspend Windows aggressively turns off USB ports to save power, which frequently causes the "USB Device Not Recognized" error. You must disable this behavior for your Root Hubs. Press Win + X and select Device Manager. Expand Universal Serial Bus controllers and locate each USB Root Hub. Right-click it and select Properties. Navigate to the Power Management tab and uncheck Allow the computer to turn off this device to save power. Click OK and restart your PC. [IMAGE: Device Manager showing USB Root Hub properties and the Power Management tab] While you are in the Power Management tab, check the Advanced tab and ensure USB Selective Suspend is disabled under Power Options via the Control Panel. This forces Windows to keep the USB bus active at all times. How to fix your missing USB drive Once you've performed the above steps, you're in a better place to fix whatever is causing your USB drive to not show up. Here are a few possible solutions based on what you found when searching for the drive in Disk Management: If Windows asks you to format the partition when you insert it Repair System Files and Drivers If the drive still does not appear after checking the basics and disabling power savings, Windows system files or driver conflicts may be blocking communication. Start by running the built-in Hardware Troubleshooter. Press Win + R, type msdt.exe -id DeviceDiagnostic, and press Enter. Follow the prompts to let Windows scan for USB controller errors. Next, verify system integrity. Open a Command Prompt as Administrator. Run the following command and wait for it to finish: sfc /scannow If it finds corrupted files and repairs them, restart your PC. If the problem persists, run the Deployment Image Servicing and Management tool to fix the underlying Windows image: DISM /Online /Cleanup-Image /RestoreHealth Once those commands complete, return to Device Manager. Expand Disk Drives and Universal Serial Bus controllers. Right-click any device with a yellow exclamation mark and select Uninstall device. Do not worry about the warning; Windows will automatically reinstall the correct driver stack upon reboot. This forces a clean slate for the USB controller. If Windows can see the drive but can't read it, it's possible the drive was formatted with a file system Windows doesn't normally support. For example, this can occur if you format a drive with the APFS file system on a Mac or with the ext4 file system on a Linux PC. If you connect a drive with a foreign file system, Windows will tell you it needs to format the drive before it can use it. Don't format the disk yet! This will erase any files on the disk. If you don't need the files on the disk, you can agree to format it—but be sure the drive doesn't have any important files on it before you do. You will lose any data on the USB drive when you format it. To read a drive like this one, you can either connect it to the Mac or Linux PC it was made on and copy your files off of it onto another drive, or you can use software that lets you read Mac-formatted drives or Linux file systems in Windows. After you copy the files off the drive, you can agree to let Windows format (erase) the disk. It will appear as an empty drive that is now compatible with Windows. If other Windows PCs can see the drive, but your current one can't If other computers detect the drive when you plug it in, but your current computer doesn't, it's possible there's a driver problem in Windows. To check for this, open the Device Manager. On Windows 11 (or Windows 10), right-click the Start button and select "Device Manager." Expand the "Disk Drives" and "USB Serial Bus controllers" sections and look for any devices with a yellow exclamation mark on their icon. If you see a device with an error icon, right-click it and select "Properties." You'll see an error message with more information. Search the web for this error message to find more information. To fix driver problems, you may want to right-click the device, choose Properties, and head to the Driver tab. Use the "Update Driver" button to attempt to install an updated driver, click "Roll Back Driver" to roll back the driver to a previous one if it just stopped working, or use the "Uninstall" button to uninstall the driver and hope Windows automatically reinstalls one that will work. If you see the drive in Disk Management, and it has partitions If the drive appears in Disk Management and you see one or more partitions on the drive—with a blue bar along the top—it may not appear in File Explorer because it needs to be assigned drive letters. To do this, right-click the partition on the drive in Disk Management and select "Change Drive Letter and Paths." If you can't click "Change Drive Letter and Paths," that's because Windows doesn't support the file system on the partition. You may see that the partition has no drive letter assigned to it. Assign a drive letter, and it should just work. To assign a drive letter, click the "Add" button and assign a drive letter of your choice to the drive. Click "OK," and it will appear in File Explorer or File Explorer with that drive letter. If you see the drive in Disk Management, but it's empty If you see the drive in Disk Management, but it says Unallocated—with a black bar along the top—that means that the drive is completely empty and unformatted. To format it so Windows can use it, just right-click the unallocated space in Disk Management and select "New Simple Volume." Choose the maximum possible size for the partition and assign a drive letter—you can let Windows automatically choose a drive letter. If you want the drive to be compatible with as many other operating systems and devices as possible, format it with the exFAT file system when Windows asks. Otherwise, if you're only using it on Windows machines, NTFS is fine. After it's done, the drive should be usable. If you see the drive in Disk Management, but you can't format it In some cases, the drive may have a very messy partition scheme. You may even see "protected" partitions that you can't delete from within Disk Management. Or the partition on the drive may be too small because the drive has protected partitions wasting space on it. You can "clean" the drive to clean up that mess, wiping all the files and partition information from the drive and making it usable once more. First, back up any important data on the drive if the drive has important data on it. The cleaning process will wipe the drive. To clean the drive, you'll need to open a Command Prompt window as Administrator and use the diskpart command to "clean" the appropriate drive. Cleaning a flash drive (or any drive) will wipe all of the data, so be careful that you select the correct drive. You can then create partitions on the empty drive. With any luck, after following these steps, your drive will be in good working condition again. If none of that works, and the drive isn't recognized in other computers, there is a real possibility that your USB drive is completely dead. Any number of physical or electrical problems could cause a drive to die, but once it does, no amount of finicking with Windows will ever bring it back. If the drive has important data on it, it might be possible for a professional to fix it and recover your data, but that job requires specialized equipment, knowledge, and training. In most cases, you're better off just picking up a new once—especially since flash storage is so inexpensive now.
