Unable to install Arch Linux on SD card via Virtual Box

My aim is to create a bootable SD card with Arch Linux, for my Raspberry Pi.

I have been trying to follow this guide without success.

So far I have:

• A working Arch Linux virtual box, as my host is OSX


• Formatted the SDcard to FAT before the process


• Mounted my SDcard to and it is visible by the VM as storage

I go to start following the guide and things start going wrong.

Unsure on how to 'get' at the device that is available I ran /dev/disk/by-label and saw my device @RECOVERY which is the correct label. Great.

I then executed step 2 of the guide, as my SDcard is formatted. mkfs.vfat /dev/disk/RECOVERY.. the only thing that happened is that my SDcard is no longer visible in /dev/disk/by-label ! My assumption is that I have in some way mounted the device but I am now out of my depth, even after googling for mounted devices/partitions I remain lost.

What is my equivalent of /dev/sdX1 and how do I complete step 3 and 4 of the guide?

Cheers
