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 via File Manager

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: Output from dmesg | tail

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

Do you use a self-compiled kernel or default Ubuntu one? –  qbi Nov 7 '13 at 12:12
    
The default one –  cshubhamrao Nov 7 '13 at 12:25

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.
