Yup, you'll have lost all your personal data that wasn't backed up. Contacts, favourites, photos, music, downloaded files..
If your external disk was empty, you should have had no problem creating the disk image on it.
*** Could you clarify what you meant by the 3 disks? Did you mean partitions on your HDD in your PC?
If so, what was the error message you got? Was it perhaps about reading the 3rd partition? I'm trying to read between the lines here. If it was a read problem, then you will need to resolve that.
