I tried to move a film into a folder.
So I clicked 'cut' in the original folder and then I touched the folder named 'films' on my external hard disk,
just to make sure I wasn't trying to put the movie into two folders at the same time.
The folder then disappeared.
A minute or so later, I saw a pop-up; 'Ubuntu has experienced an internal error.'.
And the folder did not come back, either.
I tried Disk-utility to scan the disc and see if the folder had been moved, inside another folder maybe,
but nothing to be seen.
'Search' showed nothing either.
All the movies were Super 8's, which I had digitized over the last few weeks.
They can't go through the projector again, I was lucky I got as far as I did.
So this means a great loss.
I know the files must be still on the hard disk, and I would be able to retrieve them under Windows,
but how do I go about getting them back running Linux???
Any advice on how to do this would be really appreciated.
