Hi I have an Iomega HD for mac. I was writing a ubuntu server image to another drive but accidentally selected my 500GB Iomega with my files on it. The command I ran was:
sudo dd if=/Users/myuser/Desktop/ubuntu/ubuntuserver.img of=/dev/rdisk1 bs=1m
this shouldve been another disk.
I have downloaded testdisk but have no idea how to recover using it.
what are my best options for retrieving the data?
