1Preparations before formatting SD card

Before you start to format SD card, you should grasp the basic information about it.

What does formatting SD card mean?

SD card formatting is the process of preparing a flash device for data storage. It cleans the SD card by removing previously existing data and information on the card (low level formatting) and creating a new file system (high level formatting).

SD formatting is different from deleting file. When you use erasing or deleting function in the SD card, the actual image data remains on the memory card, but will be overwritten when new images are taken.

SD format on computer V.S. on camera

Memory card formatting can be realized through the camera or through a computer. Both the 2 ways can clean all files and free up more space for use in the camera. In the latter case, a memory card reader that connects to the computer is required.

Formatting a card with a computer is often faster, while in-camera formatting is generally recommended for obtaining a file system that is optimized for the particular camera it will be used with.

Back up SD card data before formatting

Formatting will destroy the files in the SD card. For avoiding any regret, you had better backup your SD card data firstly.
