This doesn't look like a partition table
Probably you selected the wrong device.

Hi Andrew,

The mount command (according to the fdisk output) you need to use is:
mount -t ntfs /dev/mapper/nvidia_ebdfedde1 /media/store
Note the partition number in the above command!

If that doesnt work please post the output of ls /dev/mapper

Thanks for your response Danny. I've tried using the mount -t ntfs /dev/mapper/nvidia_ebdfedde1 /media/store command. Please look at the bottom of my OP to see its output. /dev/mapper/nvidia_ebdfedde1 was created after I ran kpartx -a nvidia_ebdfedde.

Here's the output of ls /dev/mapper:

root@afs:/dev/mapper# ls
afs-root afs-swap_1 control cryptswap1 nvidia_ebdfedde nvidia_ebdfedde1

Thanks Phillip Susi, that solved my question.
