Hi,

There may be technical problem with the flash drive or it may be corrupted by Virus. However, to solve the problem try to format your flash drive. If you face any problem to format your flash drive scan it for Virus. Scan the flash drive with an updated version of Antivirus. Your running Antivirus with your computer may not be updated. Collect an update version of Antivirus to scan the flash drive. On completion of successful scanning try to format the flash drive. It will take several minutes. But you are recommended to format it. If there is a technical problem contact the experts.    

I hope you understand it.

Thanks

If your USB flash drive suddenly became inaccessible or unreadable, there are only two possible reasons for that: the file system is damaged or the flash drive itself may have already reached its EOL or end of life. First, try fixing it using the Windows Check Disk utility. Insert your USB flash drive to your computer then double-click My Computer. Right-click on your flash drive and select Properties.

In Properties window, select Tools tab and click Check Now under “Error checking”.

In the Check Disk window, check “Automatically fix file system errors” and then click Start.

Wait until it is finished checking the drive. Once finished, check if you can browse the flash drive. If it is still inaccessible, try formatting the USB flash drive. Right-click on your flash drive and select Format then start formatting the device. Aside from using the Check Disk utility, you can also use PC Tools Performance Toolkit to check your flash drive.

Download and install it on your computer. Use the supplied password to unpack. Download 7-Zip from 7-Zip File Archiver if you don’t have it. To check the USB flash drive, start PC Tools Performance Toolkit. Select Recovery tab and click Repair Drives. Under Select Drive Operation, select Surface Scan. Select your USB flash drive from the list and click Start. See if this fixes the problem. Additionally, if you want to register your copy of PC Tools, click Start, Run, type without quotes “cmd” then hit Enter. In the command prompt window, type without quotes “cdprogram filespc toolspc tools utilities” then hit Enter. Again type without quotes “pt register” then hit Enter. Open the “Keys.txt” file included in the download and copy the details to the registration dialog to register.

If the flash drive can’t be fixed, it is possible the device may have already reached its end of life. All USB flash drives have their maximum number of writes. As you use it to store your files, the number of writes increases every time you copy a file to it or delete a file.

When the device hit the ceiling for the maximum number of writes, it will suddenly become unreadable. At this point, it is no longer possible to fix the drive and recover the files. Though the maximum number of writes is not written on its label or in the box, it is there and that’s how it is designed.
