Ubuntu – How to change permission external hard drive in ubuntu 12.04

12.04hard drivepermissions

I want to copy any file to my external hard drive.
But always when I tried to do this I have next output:

cp: cannot create regular file /media/NameOfCard/[file]' : Read only file system

I also tried:

sudo chmod -R 775 /media/NameOfCard
sudo chmod -R 777 /media/NameOfCard

But the same effect – ... Read only file system

Update:

After mount I have next output:

nazar_art@nazar-desctop:~$ mount
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)

udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)

none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
/dev/sdb1 on /media/sdb1 type vfat (rw)

gvfs-fuse-daemon on /home/nazar_art/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=nazar_art)

Any suggestions?
