Well. I was trying to write an image to USB key and i wound up writing the image to the ipod that was plugged in. Thank god for backups. I had an image of the osos partition and MBR and was able to save it. Fortunately it didnt get far enough to clobber my media partition so after putting my MBR and OSOS back everything works charmingly! Glad i made an backup! TLDR. DD’d to my ipod instaid of a flash drive!
