Ubuntu should not have messed with your external except to add a trash bin (hidden). Try and see if your folder is hidden for some reason by going to folder preferences in windows and click show all. I have seen viruses that mask files and folders from windows, did you connect your hdd to a windows computer that may have been infected? If you have the space on the hdd, boot to your Ubuntu cd/USB and make a copy of the desired folder onto the hdd or to your internal hdd and see if that doesn't fix you up.
BTW, any reason you were using a 3 year old version of Ubuntu rather than a newer one? More and more compatibility issues get cleared up with each release.
