How to Fix SD Card Fragment Error?

“I have a 16GB FAT32 formatted SD card. I downloaded latest version of kernel onto the card. Then I put a game in root folder and started it with my 3DS. I got into the main menu, opened games tab and found my game in the list. When I clicked on the game I got a message stated that, “SD card fragment error! Backup SD card, then perform full format”. And now am stuck on the loading screen. I am worried because, along with games I have stored lot of important files, photos on my SD card. And it is asking me to format!! If I format it then I will lose all my stuffs. Hope I can find ways to handle this situation”.

Many users get the fragmentation error while using SD cards. When SD card saves new file, it breaks the file into many number of bits. Hence, data ends up in spreading all over the card. As information of one file is stored on many spots within the card memory, the card is in fragmented state. When you access data from fragmented card, it has to pull every bit from each location. This is generally very tough than fetching one constant block of data from a sole position on the card. This may slow down the processing speed of card and cause fragment errors.

So now how to solve this problem? When you meet this crisis it is wiser to backup all your data from the card first. Later you need to initialize the SD card to clear-out fragmentation.
