Hi I can't see my usb external hard drive.

With disk utility it says it's mounted. But I can't find it on the right of nautilus file explorer.

When I try to mounted again, obviously it says it's mounted already. It gave me the error.

mount: according to mtab, /dev/sdc1 is already mounted on /

I google around but didn't find any answer. My disk works fine on Win XP. here is what fdisk -l says:

here's what more /etc/fstab says:

# for a device; this may be used with UUID= as a more robust way to name

I also did the ntfsfix. the command was succesful

here is the message.

lung@lung-KN226AAR-ABA-m8407c:~$ sudo ntfsfix /dev/sdb1
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
NTFS volume version is 3.1.

mount: according to mtab, /dev/sdc1 is already mounted on /

As it says it is mounted on root directory, you can find it in nautilus 'Computer' partition or 'System' partition.

If you don't find, try using terminal

cd /
ls
