Last 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'am agree with this as it’s not worth putting your faith in a USB drive that’s showing signs of unreliability again and again.
