Take a look at the unfortunate scenario below.
You could probably be in a similar conundrum or worse; You have a damaged/corrupted flash drive and landed on this guide because you wanted to learn how to do a flash drive repair. If that is the case, then I’m happy to tell you that you’ve just hit the jackpot! This updated 2019 expert guide will show you step by step how to fix a corrupted flash drive using native tools and a flash drive repair tool we used called Recoverit (IS). Read on to find out how to do flash disk repair the easy way.
The first thing that comes to mind when you can’t open or access the files on a corrupted flash drive is to format it. Though this will work most of the time, it means you will potentially lose all the data on the flash drive unless you have access to a specialized flash drive repair software like Recoverit (IS). Before you go ahead to format the flash drive, there are a few techniques you can try to fix a corrupted flash drive without formatting it. Here are a few of them:
Sometimes a malfunctioning or inactive USB port on your computer could be the culprit preventing your operating system from detecting or reading your flash drive correctly.
This can happen if you have a habit of quickly plugging in and unplugging your flash drives without correctly unmounting them or mid -file transfer. Here are the ways you can test if your USB port is working on windows 10.
i. To Test Your USB Port-Remove the Flash Disk and Reinsert It
This usually solves the detection problem, especially if you had not inserted the flash drive properly the first time. Look out for a windows notification telling you that you have inserted new hardware. You should also be able to hear the familiar Windows chiming notification sound if you have audio enabled on your computer. Windows will even automatically open the flash drive’s contents in explorer if all is well with the flash drive. Try another USB port if this fails.
ii. To Test Your USB Port- Physical Examination
Sometimes your USB port or USB drive may have physical damage or have accumulated some dirt that is causing it to malfunction. It is best to observe the inside part of the USB port on the computer and flash drive and remove any dirt that may be inside there using a soft brush with long bristles.
Also, try and gently wiggle the USB flash drive if it is loose once connected and see if Windows can recognize it. Don’t overdo it though as you may end up damaging the tiny connectors inside the port.
iii. To Test Your USB Port -Test the USB Port Using the Device Manager
You can use the windows menu system to locate the device manager so you can test if your USB port is in working condition or better yet, use the following easy shorter route.
Step 1 Click on the Windows start icon on the bottom left side of your Windows 10 desktop.
Step 2 Type Run and press the enter key. This will open the Run dialog box anywhere on the desktop.
Step 3 Click inside the empty text box on the opened Run Dialog box and type this Command as it appears here; devmgmt.msc. Now click on the OK button. This will take you straight the device manager in windows 10. Easy Huh?
Step 4 With the device manager window open, you can now locate the computer icon on the list and click on it to highlight it.
Final Step- With the computer icon highlighted on the list, locate the action menu item at the top and click on it then choose the “Scan for Hardware Changes option.” This will force windows to scan all the ports for any new hardware and hopefully recognize your inserted flash drive and add it. This should make it available for you to access on windows explorer.
iv. To Test Your USB Port- Toggle Disable and Enable the USB Controller
Step 1 Use the above steps to access the device manager window on your computer quickly.
Step 2 On the list of devices in the device manager window, locate the Universal Serial Bus controllers’ item and click to expand it.
Step 3 Now locate the specific USB controller on the expanded list then right click on and choose “disable device.” You can repeat this step for all the USB items listed if you are not sure which of them you’ve plugged your flash drive onto.
Step 4Now right click the disabled USB controller and re-enable it. This will restart that specific USB controller and most likely make it recognize your USB drive correctly. Make sure you re-enable all the USB controllers you disabled in the previous step.
Use this method if you can see the USB drive on your computer, but its content is corrupted due to an error in the disk file system or partitioning. This is a common occurrence that may have been caused by many things such as; viruses, incompatibility, incomplete formats, wrong file system type (FAT32, NTFS, etc.), lost and corrupted partitions, etc. Windows ships with a nifty little disk management utility that you can use to fix a corrupted flash drive.
How to recover corrupted flash drive using disk management in windows 10; follow these steps.
As with many with other native windows utilities, there are several ways to gain access to the disk management interface on windows 10.
