Please help, How can I restore a corrupted ntfs drive? I have been backing up dvd iso files to a external hard drive with dvd shrink. I connected the drive to another pc the first burn was good, but when I selected tried to select another iso file I got an error message saying: not accessable. the file or directory is corrupted and unreadable. I had already run a virus scan on both computers and on the external drive before connecting. In windows XP computer management console it shows the external drive with no NTFS file system and 100% free space like its all gone.Under my computer it shows that its full and the file system is raw.
