"FAT-fs: IO charset iso8859-1 not found" error while mounting FAT Drives
I am unable to mount any fat32
or fat16
formatted usb disks under Ubuntu 13.10.
The thing here to note is that it is happening only with fat
formatted Disks. ntfs
, ext
formatted external usb disks work well
(I tried formatting the same with ext4
and it worked)
While mounting via nautilus
:
Error while mounting from terminal:
root@shubham-pc:~# mount -t vfat /dev/sdc1 /media/shubham/n
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
As suggested by the error:

All normal
Tried re-creating the whole partition table and then formatting as fat32
but to no avail so the possibility of corrupted drive is ruled out.
Tried the same with around 4 Disks or so and all have the same things
Apparently, your kernel somehow has problems (maybe a bug). Since there is an updated version available, install it (version 3.11.0-13-generic
)
sudo apt-get install linux-generic
now reboot in your new kernel.
I had the same problem a few days ago with 4.4.0-57. modprobe nls_iso8859-1
threw an error, and without that module, that "IO charset not found" message appears.
Turns out the root filesystem was damaged.
After a thorough fsck and reinstalling of the kernel (forced with apt-get install --reinstall
), that module loads again, and I can mount my USB sticks.
@larskholte Even if the update to 4.4.0-57 fixed your problem by replacing the bad module, be sure to fsck your filesystems! That module not loading is only a symptom of a much bigger problem.
