Reasons to Format a Bootable SD Card
An SD card is a special type of memory card commonly used in cell phones, digital cameras, and other portable devices. So, what is a bootable SD card? Generally speaking, a bootable SD card is a special disc that contains a bootable operating system. It allows you to boot computers that have boot problems or suffer system crashes.
Sometimes you may need to format a bootable SD card. Here are three main reasons:
- Different devices support different file systems. To accommodate a specific device, you must format the bootable SD card as an NTFS, FAT32, or exFAT file system.
- Format the SD card to extend its life. Bootable SD cards inevitably develop bad sectors or corruption issues after being used for a long time. By formatting, you may get rid of these troubles.
- No bootable SD card is required. Your current bootable SD card may no longer meet your computing requirements. Therefore, you can format it for other purposes.
