Think I saw the problem. Before your EOS0digital drive. there is a black portion. means unformatted or such. is there a data important in there? format that black one with standard MBR. then delete the EOS and then delete again the black portion where you format it. And then format the whole drive.
Sorry. not good in writing guide but it has something to do the partition before your EOS. if I am not mistaken,
if you know how to use linux, Gparted is best software I have ever use for formatting or fixing drive.
