Reformatting your SD card

Reformatting your SD card
Prev	Working with your SD card	Next

If you plan on using your SD card purely for file storage, you might want to reformat it with the ext2 filesystem - a perfectly acceptable thing to do:

# umount /mnt/card
# mkfs.ext2 /dev/mmcda1
# mount /mnt/card

Note that, since the entry for the SD card in the file /etc/fstab specifies a filesystem type of "auto", you don't even need to change anything in that file for the new ext2 filesystem to be mounted properly at boot time.

	Important
Obviously, if you're going to reformat your SD card, you'll want to do this before storing anything on it. And don't forget to remount it after reformatting. In addition, if you reformat, you might want to change the mount options for the new ext2 filesystem to include "noatime", or change "sync" to "async", for better performance. (If you have no idea what this means, check the options for the mount command.
