the disk drive for /media/sdc1 is not ready or not presented - in ubuntu
12.04

When I tried boot PC - I saw next message:
the disk drive for /media/sdc1 is not ready or not presented
Continue to wait or Press S to skip mounting or M for manual recovery
I used S and now want to know how to solve this issue. Here is my fdisk

now this is output after sudo fdisk -l /dev/sdc running:
