Unable to remove files from my passport

My Passport will not let me put files from the harddrive onto my PC so that I can access them. The files all work fine on the hard drive, and I can put them onto my PC but once transfrered they are not in an accessible format i.e they open in dream weaver and are just html or just come up with an error message that file cannot be found. i am not sure if the drive was formatted correctly in the first place. is there a way of recovery? i need to keep the files and want to use the hard drive for transporting other files.


How are you transferring the files to your drive? Are you using a automatic backup software or manually drag and dropping the files? Also, does this situation happens with any file type or just dreamweaver files?
