Can't open JPGs Files on my Mac.

So I have an external hard drive that would READ/WRITE on my Mac because the format was only for Windows. I found some software to change the format of the external drive to the readable and writable format for Mac and Windows. As I did this, I was not aware that it would delete all my files that I had on there. After I reformatted it, I found some more software that would return all my files that I lost on my External Drive. As i restored everything, it was a mess. Some JPGs were viewable and some said they were corrupted or something and somehow got messed up when I was retrieving the data again. You can see the kind of files im dealing with so you can get an idea.

I need to be able to access these pictures, so if you guys would help me out, it would be great!

When you recover files it's very much hit and miss as to whether they are intact or not.

131k for an image file (depending on what it is) is tiny - think icon sized. So I suspect that while the file name and entry has been found the data has not been recovered.

If a disk is formatted using the same file structure you can often recover data but changing the file structure makes it much more difficult. If these files are of great importance I would stop using it immediately and contact a commercial data recovery specialist.
