Someone may think it’s easy to transfer files from USB to another USB via “Copy and Paste”. It’s useful if your USB is just a data storage device. However, it’s cumbersome and time-consuming. More so, if your USB is a bootable device, that does not work. You cannot copy and paste the master boot record (MBR) and other files connected to secure boot your computer. And here, a question come out: how to protect your data on the USB drive?

The experienced users may choose to clone USB flash drive with a USB clone tool. Why clone USB drive? Is it able to ensure data security and secure boot?

Why do you need to clone USB drive?

A USB flash drive or pen drive can be used for a lot of things. It allows you to:

  • run portable version of programs and games,
  • create Windows recovery disk,
  • create Windows installation media,
  • try open-source operating system, etc.

As it is cheap and convenient, many users have one or more USB drives for a certain purpose. Here comes an example:

“Looking for a reliable and easy-to-use USB clone tool… I have two USB sticks in hand and I’d like to clone one of the USB (bootable) to the other (newly purchased) for upgrading. Is there any easy way to accomplish? I’m not so familiar with computer knowledge, so… Thanks in advance.”

Since USB drives are very small, they are inclined to go missing. What’s more, with lots of times of plug-in and plug-out, your USB drive can get infected by virus from a virus affected computer. To avoid data loss in these unexpected events, you can clone your USB drive as a backup copy.

A clone is different from just copying and pasting the files from one to another. Simply copying files may skip some crucial files, ending up the portable program corrupted or OS unbootable. A USB drive clone is much safer and quicker than just copy and paste. If you clone a bootable USB drive, the cloned one will remain bootable.

When you see one of the USB hard drive failure symptoms, you should clone this drive to another good working USB drive to replace it. You can never be more careful about your data, so it is always a good practice to have a backup or clone of your USB drive.
