I partitioned my WD passport Ultra in error when trying to get it to show in file manager.. Since upgrading to windows 10 it doesn't show up now. I can see the area of disk which has all my files stored by I cannot access them. I have followed all instructions in disk management but the drive is not listed by name only with a picture and there are 4 of these plus the volume I created in error. How can I get this working again as I have all my important files on here and unable to get into it. Please advise. Thank you.
