  • Create, format, delete, copy, and merge partitions
  • Clone an entire disk to another even the destination partition is smaller than the source

Last Advice: If your SD card has the I/O device error, you may have a rare chance to repair the corrupted SD card. But you can still try the USB production tool to repair the corrupted memory card. You can search the internet and find one to try. 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 agree with this as it's not worth putting your faith in a USB drive that's showing signs of unreliability again and again.
