I have two hard drives, one 80 and one 160gb. The 80gb was split into two partitions, 20 and 60. The 20 was my OS partition. I just recently added the 160gb and I decided I wanted to reformat my os partition. I just formatted it and installed the new os, but it doesn't recognize my 160gb! it sees it as "unpartitioned space". I had some very important files on that hard drive, is there any way I can recover it? I don't understand why the files on the 160gb are gone, since I only formatted the 20gb partition.
