PC FILE INSPECTOR (google.com) might help. Sometimes it's that old HIDDEN file or OWNERSHIP issue but your post is too slim on detail.
I had a desktop computer die on me a couple of years ago and I lost all the information. I was browsing the internet and discovered hard drive enclosures. I got my Dell Inspiron 6000 to recognize the old hard drive, but when I browse through the drive I can't find any of the files I want. I lost a ton of pictures and music files that I'd like to get back. If anyone could help me that would be great.
