Well,
I posted this answer when you first asked it but I don't know if you tried it or not. Your PC software may reformat it for you. If you use cakewalk go to save as and then choose the same format as your Korg. Try the same with whatever editor/librarian, sequence, editing, software you may have.
I don't know which is which so you will just have to spend all of 2 minutes to figure out if your Korg is format 0 or format 1.
