The case: transfer 16GB SD card to 32GB

“Simply put - is there a clean, painless way to transfer everything from SD card A to SD card B? I've got a 32GB card on the way but have been extensively using the 16GB that now has everything from a solid collection of MP3s to games to movies to... you name it. I'm just worried I'm going to break some file paths or lose something in the move if I sloppily attempt to copy everything over from the 16 to the 32. Thanks for any help.”

From the real case mentioned above we can get that the user wants to know how to transfer data from 16GB to 32GB. As everyone knows, various external hard drives can help users store their precious data efficiently like SD card, hard disk drive, and solid state disk, etc.

With the increasing amounts of data, it is necessary to clone hard drive with different size, for example, clone 16GB SD card to 32GB. Here are three related reasons.

  • Use the cloned drive as a backup. To prevent data loss, many people use the cloned drive as a backup just in case.
