Copying files from one USB drive to another simply takes the usual drag-and-drop method in File Explorer on Windows. If you are duplicating all the data sector by sector and keeping all the low-level data intact, you need special software.
The USB Drive Clone software creates a precise sector-by-sector copy of a USB drive, including but not limited to MBR (Master Boot Record), boot records, OS boot loaders, partition tables, active partition flags, and all partitions as well as space in between. Even hidden partitions can be duplicated. USB Drive Clone software recognizes more than 293 partition types, even if an unknown partition type could be duplicated without extra effort. The software does not rely on the file system or the operating system on the USB drive; it could be Windows, Linux, Unix, MacOS, or any other OS with a good number of partitions. Bad sectors can be detected by the software, and the software always tries 3 times to read the data out of the bad sectors. In case you would like to make an accurate copy of a to-be-damaged USB drive and attempt data recovery as much as possible, just give it a go! The software becomes handy for those who desire for an exact copy of a USB drive.
The supported USB drives include USB memory stick, USB flash drive, USB pen drive, USB thumb drive, and portable USB drive. The software performs synchronous duplication other than asynchronous duplication meaning that no image file of the source USB drive is created in the course of the data duplication. Serial number is never cloned by the software, as it is a unique hardware identification embedded in the firmware of the USB drive. An interesting feature of the software is safe removal, which allows to eject either one USB drive or both USB drives after the data duplication process completes so that you can unplug the USB drives from your host computer.
Bootable USB drives can be cloned by the software without loss of the bootable characteristic and capability.
