What is the Best Way to Clear An SD Card?
Generally, there are two ways for users to clear the stored data in an SD Card, deleting, and formatting. Some users might be confused about these two terms, and wondering what is the best way to clear the SD Card. Here we will tell you the difference between delete and format and tell you which way should you use.
Delete: When deleting a file, the file is removed and the file system will mark it as an empty space. Claiming that this space is now available for rewriting. Usually, the deleted files can be recovered if no overwrite happens.
Format: When formatting a storage device, the system will completely erase the index and restore it to the original empty settings. If you perform a quick format, you will have a great chance of recovering formatted data. If the full format is performed, the chance of recovering the lost data is small.
So if you want to completely clear an SD Card, you should perform a full format to erase all data on your SD Card. Because it will not only delete the files and content but also wipe all the index and cache files.
To format a storage device, both Windows and third-party software provide users with efficient ways. In this part, we will tell you how to use Windows built-in features to format an SD Card.
