dosfsck is unable to repair FS and kernel show this warning:

FAT-fs (sdc1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

This problem happends when 3.8+ kernel does not properly umount fat partion. For fixing this problem dosfstools v3.0.14+ is needed. See: https://lkml.org/lkml/2013/5/6/342

Because in precise is only version 3.0.12-1ubuntu1.1, it cannot repair these FS. So please update in precise dosfsck to at least version v3.0.14 which can properly fix fat32 partitions.
