I am going to format my Sony External Memory Card
Card Name in My Linux System : /media/PHONE CARD
1. Login with root mode or switch to su
root@antony# sudo su
[sudo] password for anthoniraj:
2. Check the device name of the USB using fdisk or mount command
root@antony# mount
/dev/sda1 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
lrm on /lib/modules/2.6.22-14-generic/volatile type tmpfs (rw)
/dev/sda5 on /media/sda2 type ext3 (rw)
/dev/sda6 on /media/sda3 type ext3 (rw)
securityfs on /sys/kernel/security type securityfs (rw)
/dev/sdb1 on /media/PHONE type vfat (rw,nosuid,nodev,shortname=mixed,uid=1000,utf8,umask=077,usefree)
/dev/sdc1 on /media/PHONE CARD type vfat (rw,nosuid,nodev,shortname=mixed,uid=1000,utf8,umask=077,usefree)
(or)
root@antony# fdisk -l

The Last line of both commands is My Memory card device name i.e., /dev/sdc1
3. Unmount the USB drive using umount command
root@antony# umount /dev/sdc1
4. Format the drive using mkdosfs command
root@antony# mkdosfs -F 16 -n ‘Antony’ /dev/sdc1
mkdosfs 2.11 (12 Mar 2005)
Here
-F 16 is the option used for specifying FAT file system (FAT16)
-n is the drive lable
both are optional.If options are omitted, mkdosfs automatically determines the file system size
