 If you cannot read or recognize the USB flash drive on your computer, don't panic. In this video, I'll show you how to fix pen drive or USB drive not detected issue. In case your pen drive is completely damaged, I'll also share an easy way to recover your data from it. So let's quickly look into the solutions. Method number 1 First and the most basic way is to make sure that you have connected the USB drive to the computer properly. Sometimes this issue occurs due to loose connections. If your USB drive won't work via one USB port, try a different one on your computer. Method number 2 Update USB drive driver The other reason for the USB pen drive not showing is due to the outdated USB drivers. To update USB drivers, right click on Windows icon and select Device Manager from the list. Now expand the Universal Serial Bus Controllers option and right click on the USB root hub or generic USB hub and then click on Update Driver. Now click on Search automatically for drivers. Your system will automatically find and update the drivers. Once the process is complete, restart your computer and try connecting your pen drive again. If you are the one who finds manually updating the driver time consuming then you can use this tool called Advanced Driver Updater to find and update all the drivers automatically. Just download and install the software. You can also use the link given in the description below. Once installed, click on the Start Scan Now button. Wait for the scanning process to complete. Now it will show you a list of all the outdated drivers. Click the Update Driver next to the driver you wish to update. If you want to update all the outdated drivers at once, click on Update All. Reboot the system after updating the drivers. Method number 3 Change the drive letter of the pen drive If the drive letter of your pen drive is the same as the drive letter of one of the partitions existing on your computer, your pen drive will not show up in Windows. To change the drive letter of your device, first connect your USB drive to the computer. Right click on Windows icon and select Disk Management from the list. In the Disk Management window, right click the volume on your USB drive and select Change Drive Letter and Paths. In the next window, click on Change. Click on the drop-down menu and assign a new drive letter to your pen drive and click OK. Now reinsert the USB drive and check if your problem is fixed. Method number 4 Fix file system errors If your USB flash drive has file system errors, it will show up as RAW and become inaccessible. To fix the file system error, you must format the drive to convert RAW to NTFS. First, connect your USB drive to the computer. Right click on the Windows icon and select Disk Management from the list. In the Disk Management window, right click the volume on your USB drive and select Format. Now click on the drop-down menu next to File System and select NTFS. Click on OK. Now you will be able to access your pen drive easily. By following these steps, your pen drive should become accessible with the new NTFS file system. It's important to note that this process will result in the loss of all data stored on the drive. If you need to recover lost data from a damaged, corrupted or formatted drive, you can use Advanced Disk Recovery software. Download and install Advanced Disk Recovery on your Windows PC. I'll also add the link in the description for your easy access. Connect your USB drive to the computer. Select the drive where your deleted file was stored to scan. As we want to recover data from the USB drive, we'll select the pen drive and click on Start Scan. Now from here, select the type of scan. I suggest selecting Deep Scan as it increases your chances of recovering and then hit Next. Wait for the process to get completed. Once the scan is complete, you'll see the number of deleted files found. You can preview the files before recovering them. Then select the files you want to recover and click on Recover Now. Now click OK and select a location where you want to store the file or folder after recovery. To avoid overwriting data, make sure to select a different location to save the recovered files. Do not choose the same location from where you are recovering the files. Wait for the recovery process to complete. So that's it. If you found this video helpful, give it a big thumbs up.
