After configuring my USB to be FAT32 through fdisk, I unmounted it, and when I mounted it again, it wouldn't work. Upon running dmesg | tail, I found I had not installed a valid FAT system. How can I get a fat system working on the usb?

if you not install a valid fat system in your USB drive then you need to format it again in fat

you can format your USB drive by the following way in fat that will work in fedora

in Fedora there is many method by which you can format your pendrive

1 - by Disk utility see the video (same as the ubuntu)

2- by Gparted tool see the video

// you can install it or you can install is by typing

yum install gparted

3- by using Terminal see the video

go to super mode by typing "su" followed by super mode password

fdisk -l

that will show all the volume in your pc or you can also use the


to see the USB flash drive suppose it may be /deb/sdb1

umount /dev/sdb1

that un mount the drive

mkfs.vfat /dev/sdb1

to format drive into fat32 format

Here is how you format a USB drive to be FAT32 using the Disks utility in Fedora 18 (gnome 3)

  1. Insert your USB and open up the Disks utility ("Disks" in the Activities overview, or "gnome-disks" from the terminal).
  2. Click on your USB drive from the list of disks in the left hand pane. In the following example, the 4.1GB Drive is the one i want to format. image description

  3. Under the Volumes section, since I only have one partition, it is already highlighted blue, so just press the little square icon under the blue block to unmount the filesystem.

  4. Next click the little minus icon, to remove the partition. It will warn you if you want to remove the partition. Removing the partition will delete your data, so beware

  5. Now the blue block should read "free space". Click the plus icon that has appeared, to add a new partition.

  6. A dialog should appear with options for the new partition. Ensure it fills all the space (it should do this be default), also ensure that the FAT filesystem is chosen, and type in a label for your volume. Click create, and your new partition should create in a few seconds. The disk should also mount automatically.

  7. Open Files (nautilus) and check that it has mounted (it should show up towards the bottom of the left hand pane in nautilus)

hope this helps, ryanlerch
