I have a 160gb harddrive with two partitions of C and D and i reformatted C partition. I have many back up files in D such as pictures and installations and other medias. What's weird is that many applications in D that i have backed up has turned into DOS files and cannot be accessed. Many pictures files are still there however corrupted, some can still be viewed, most cannot. Why is this happening? I don't think formatting C drive has anything to do to corupt half of my D partition
