When need to clone SD card in Windows?

“Hello, experts, I can't seem to find a way to clone an SD card inserted into my PC to another external hard drive? (Ideally sector by sector).Is this possible? If possible, how do I clone my SD card step by step? I'm running Windows 10. Thanks!”

Sd Card

The SD card is a kind of non-volatile memory card, which is widely used in portable devices such as Android phones, digital cameras, media players, video game consoles and more. It provides a quite convenient way to store files, but you might need to clone your SD card in Windows in order to:

①Make a complete data backup
If everything on the SD card is important, cloning this entire SD card to another disk will make a complete data backup, effectively avoiding data loss or damage.

②Upgrade or replace SD card
If the current SD card capacity cannot satisfy your needs anymore, you can clone it to another larger one to make an easy upgrade while keeping precious data safe. Or when your current SD card is about to fail, cloning it to another good SD card can help replace it without losing data.

③Transfer files faster than copy&paste

Cloning SD card to another one is also an effective way of transferring all files from one location to another. It is much faster than mannually copying and pasting files one by one.
