File on Nomad external hard drive will not open

A few years back I got an external hard drive (Nomad) as I was working on a book and studying photography and wanted to be able to back up all my work in case of a computer crash. Well, it turned out that I did have a crash, and everything was fine until I went to open up a file that contained a bunch of Microsoft Word files for my book.

When I click on the file in attempts to open it, after a long period of not responding, an error comes up that says exactly this:

"Location is not available
H:\Scotia\Writing\Stories & Novels is not accessible.
Incorrect functon."

Is there any way that I can fix this so that I can have the files back? I'm desperate, and without these files I lose a year of work toward a novel. Any help is deeply appreciated.
