Why do you need to clone USB drive?

Nowadays, USB flash drives are very popular data storage media because they are small and portable to carry around. Many users choose to save important files onto the USB flash drive. And in order to avoid data loss when the USB drive is not recognized, you might want to make a backup of files on the USB drive.

To achieve that, you can copy files from one USB drive to another USB drive via“Ctrl+C” and “Ctrl+V” if you just have personal files or documents. However, if this USB drive is a bootable drive and includes boot files, that method will make your boot files useless, and then you will be unable to launch programs. Thus, you can choose to clone the whole USB drive or the USB hard disk to other devices. That can easily transfer mass data or even bootable files to another device.
