fdisk unfortunately can't do this and I'm not sure if there's any updated version that handles it but parted can do it.
Here's an example of how to do it:
parted /dev/sda print
1 17.4kB 1024MB 1024MB ntfs primary
2 1024MB 16144MB 15120MB ntfs primary
/dev/sda1 would be the first partiton
/dev/sda2 would be the second partition
You can then just access them like any other normal partition.........
