SD Formatting

// ANCHOR: steps

1. Insert a fresh SD card into the SD card slot or connect it via a USB card reader to your computer

   • microSD or standard SD card can be used

2. Launch a terminal

3. List all block devices, including your SD card:

   • lsblk

4. Look for your SD card in the output of the lsblk command. It will typically be listed as /dev/sdX, where X is a letter (e.g., /dev/sdb, /dev/sdc). You can identify it by its size or by checking if it has a partition (like /dev/sdX1)

5. Before formatting, you need to unmount the SD card. Replace /dev/sdX1 with the actual partition name you identified in the previous step:

   • sudo umount /dev/sdX1

6. Use the mkfs command to format the SD card. You can choose the file system type (e.g., vfat for FAT32, ext4, etc.). Replace /dev/sdX with the actual device name (without the partition number):

   • sudo mkfs.vfat /dev/sdX

7. You can verify that the SD card has been formatted by running lsblk again or by checking the file system type:

   • lsblk -f

8. Once formatting is complete, you can safely remove physically or eject the SD card:

   • sudo eject /dev/sdX //ANCHOR_END:steps
