I have a seagate 400Gb HDD with 4 partions. I used it as a back up of my data. Today i can not open any drive. The error shows "The file or directory is corrupted or unreadable". In computer management all partion are there. But without any file system. Drive properties says Used space=0,Free space=0. I want to back up all the datas. I have another 80 gb HDD with me. If i could recover the back up partion on 400 gb or how to back up the entire 400 Gb with 5 batches. So that i could recover all the datas.:huh: :huh:
