My root folder corrupted.

A few days ago, I can't boot normally into my ubuntu. I ran sudo fsck, it corrected quite many things. After that, I really can't boot into Ubuntu. I created a thread in Ubuntuforums, trying to get help and the suggested me to just reinstall, since my Home partition is in different partition, and I did it. Yes,  after reinstall, I really can used my files, programs like before. :)
