I just installed the Ubuntu 12.04 LTS. I previously had windows 7, the mistake I made was I just did not put the data I need on my hard drive anywhere else. I just did not think of it before doing it. But when I installed the Ubuntu, I just used the drive that I used previously for windows 7, and chose the option of " do not use this drive" for my other drives. So, my data is all there, I know and I want to recover the data on those drives. I used some recovery softwares in the past to recover deleted data! but most of the data would be in bad shape even if just recovered it moments after I deleted it. Any suggestions as to recover the data without much mess!
