Need help creating a Live SD card

I'm having a bit of of a nightmare.

I'm trying to create a bootable SD with Arch on it after failing miserably earlier today in VirtualBox

fdisk output :

Disk /dev/mmcblk0: 32.0 GB, 32010928128 bytes
255 heads, 63 sectors/track, 3891 cylinders, total 62521344 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0004d62e

        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1   *        8192    62521343    31256576    c  W95 FAT32 (LBA)

I've just run the command :

sudo dd if=/home/vco/linux_isos/arch/archlinux-2015.03.01-dual.iso of=/dev/mmcblk0

After running that command heres what Gparted shows. I've no idea whether this will be GPT or MBR for this?

I clicked YES to that message, here's the message that followed that

After clicking yes to the above I get this message in Gparted, I clicked ignore to that message.

After Gparted had finished scanning the system I get this information, which I'm guessing means it's broken.

At this point I have no idea what's not working or why, any help much appreciated.

Thanks

I've run the DD command again and gone into GParted.

When prompted by GParted about the GpT sigs I said 'NO' instead of 'YES' this time

After GParted finished scanning this is an image of what it shows
