If you notice that the USB drive stopped getting recognized by your computer once you plug it in. Then, the problem might not be always with the USB drive. It can be the USB port on your PC.

The best way to find this out is by connecting the USB drive to a different USB port on your computer. if you are accustomed to plugging in the USB drive in the front USB connectors, then try the rear I/O panel. In laptops, just plug the device to another USB port. If the USB drive is still not responding, then try connecting the USB drive to a different computer. Sometimes, USB ports get unresponsive either due to hardware failure or from a corrupt driver software.

In USB drives and other storage devices, the data is stored on them in places called sectors. A typical USB drive has a collection of individual sectors, where each sector can store 512 bytes of data. So the number of sectors is based on the storage capacity of the drive.

Also, when these sectors go bad or USB stick corruption happens, it results in the device not being able to work properly. So if you find that your USB device has not been up to its same level of performance, do a scan for bad sectors to see if that is the case.

Step 1: Connect the USB device to the computer.

Step 2: Right-click on the USB drive from My Computer and click on Properties.

Step 3: Navigate to the Tools Tab and click on Check under Error Checking.

Now the computer will automatically check for bad sectors on the USB device. After the scan is completed it will show you the results. If bad sectors are found on the USB drive, then Windows gives you an option to fix it.

Giving a new designation to the USB drive may help it to function properly if it’s been seen buggy at times. The process of changing the drive letter is very easy and straight forward. The following guide helps you to do the same within a few minutes.

 Changing the letter is a simple way to fix your USB device, however, it does not fix serious issues with the drive if any are present.

With every computer, there are two parts – The hardware and the software. The USB device is a hardware that plugs into the computer. However, the user interacts with the USB device and the contents within it using a software interface, most probably operating systems like Mac or Windows.

Within an operating system, software modules called drivers are responsible for connecting the hardware and software. When they have trouble working, it affects hardware and software connections. In Windows computers, there are dedicated USB drivers that oversee the USB connection. If your USB devices are not recognized by the device or if you have trouble accessing the USB drive, then most probably, you can rectify it by resealing or updating the drivers.

Step 1: Connect the USB device to the computer.

Step 2: Open Device Manager. You can find the option by pressing Windows key + X or through the control panel.

Step 3: Locate the USB drivers. It will be under the option Universal Serial Bus Controllers. Right-click on the drivers you want to update/Reinstall.

Step 4: Click Update Driver Software… to update the drivers. To reinstall the driver, click on Uninstall device.

Step 5: If you have chosen to uninstall the driver, then restart your computer. Windows will automatically install the USB drivers upon startup.

In this part we are introducing how to recover corrupted files in flash drive using cmd. CHKDSK is a tool in windows that is used to perform a check Disk function. It is a very powerful tool that can check and repair bad sectors, directory errors, lost clusters, and cross-linked files. You can access CHKDSK from the command prompt window and enter in the right syntax.

We have explained the process in the following guide, you can try it out for yourself. Please do keep in mind the fact that chkdsk scan time depends on the size of the USB storage. Hence, higher storage USB drives are going to take more time.

Step 1: Connect the USB device to the computer.

Step 2: Press Windows key + R to bring up the Run box. Type in cmd and click OK.

Step 3: In the command prompt box, type in chkdsk h /f where the h must be replaced with the drive letter of the USB drive.

Now you will see windows working through the USB drive searching and identifying bad sectors. Once found, it also gives you the option to fix it.

Diskpart is another windows tool that will help you fix USB drive without software. While CHKDSK is used for scanning the disk for errors and bad sectors, Diskpart is aimed at fixing the logical issues with the USB drive in one go.

The process involves using the Diskpart function in windows to completely erase all the data in the USB device, format it and then booting it up again. You can use the Diskpart option right from the command prompt window. The following guide shows you how to fix a corrupted usb drive without formatting using Diskpart.

Step 1: Connect the USB drive to the computer.

Step 2: Press Windows key + R to bring up the Run window. Enter the code diskpart.

Step 3: Now type in the comment list disk to view all the connected drives on the computer.

Step 4: Type select disk X where you must replace the X with the drive letter.

Step 6: Type create part primary and press enter.

Step 7: Type select partition 1 and press enter.

Step 8: Type active

Step 9: Type format FS=NTFS

Note: FS means File System. Here we are using NTFS, however, you can change it to FAT32 if required. Also, the term quick can be avoided for a deep format, which is more powerful but takes more time.

Step 10: Type assign letter=X where the X can be changed for any other letter. The command is used to assign a drive letter.

Step 11: Type exit to go out of the Diskpart function.

Once you use Diskpart, all the data within your USB drive will be deleted. So make sure that you have copied all the important files out of the drive before using Diskpart.

In some cases, a flash drive may fail to appear on your Mac computer. You will need to recover the damaged flash drive. On A Mac, go to Finder>Applications> Utilities. From there, click on Disk Utilities. Go to First Aid and Repair disk.
