This process involves Windows command prompt which is commonly known as CMD. In this, you have to enter some CMD commands and Windows will forcefully format your corrupted pen drive/SD card.

Tools provided by pen drive and SD card makers



You might not be knowing but many storage device makers like SanDisk, Kingston, Samsung, Sony, etc. provide their own low-level utilities for formatting and other repair purposes. You can find these tools by visiting the websites of the device makers or by contacting their support. In my own personal experience, such alternative SD card and USB drive repair methods have turned out to be more useful.

A little advice

There are chances that the warranty of your corrupted USB drive or SD card is still valid. So, if your storage device is giving you problems again and again, it’s advisable to invest some effort and go for a refund or replacement. I’m recommending this as it’s not worth putting your faith in a USB drive that’s showing signs of unreliability again and again.
Note: Please note that the SD card and USB repair methods described above are general ways to fix a device. Due to some device-specific issues, there could be cases when these steps might not be useful.
