Anyway, I tried formatting one of my hard drives using the gnome disks tool, and that returned an error. Error creating file system: Command-line `mkntfs -f -F -L "New Volume" "/dev/sdb"' exited with non-zero exit status 1: stdout: `Cluster size has been automatically set to 4096 bytes. Creating NTFS volume structures. ' stderr: `/dev/sdb is entire device, not just one input output error partition. mkntfs forced anyway.

Does this mean that my hard drive is fried and that I can just throw it out, or can I still save it?
