I have two text files which I cannot do anything with. They were originally each on a CF card which I transferred to a portable hard drive. Now I cannot transfer the files on to my PC. When I open up the text files using Notepad+ it’s blank even though one file is 14.3MB and the other 49.2MB.

I don’t think it’s the portable hard drive as it works normally with other files. I’ve tried repairing with checkdisk without success.

I also tried a sansdisk program I have at home but it mentioned something about ‘cyclic error’
There’s about three months’ worth of data on these files so I’m getting a bit desperate.

Any ideas what I can do?
