Ubuntu 11.10 : how to make FAT32 filesystem

install dosfstools via apt-get.

# LANG=C apt-cache search mkdos dosfstools - utilities for making and checking MS-DOS FAT filesystems dosfstools-dbg - utilities for making and checking MS-DOS FAT filesystems (debug) # apt-get install dosfstools –y

add the partition for FAT32 ( in my caes , add the new partition /dev/sdc1 )

# LANG=C fdisk /dev/sdc Command (m for help): n Command action   e   extended   p   primary partition (1-4) p Partition number (1-4, default 1): 1 First sector (2048-15826943, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-15826943, default 15826943): Using default value 15826943 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. # ls /dev/sdc* /dev/sdc  /dev/sdc1

make FAT32 filesystem with mkfsdos

# mkdosfs -F 32 -I /dev/sdc1 mkdosfs 3.0.9 (31 Jan 2010)

-F Fat-size ( 12 or 16 or 32 )

-I     

It is typical for fixed disk devices to be  partitioned  so,  by

default, you are not permitted to create a filesystem across the

entire device.  mkdosfs will  complain  and  tell  you  that  it

refuses  to  work.   This is different when using MO disks.  One

doesn't always need partitions on MO disks.  The file system can

go  directly  to the whole disk.  Under other OSes this is known

as the 'superfloppy' format.This switch will force mkdosfs to work properly.
