I tried mdadm but without success, though I don't know exactly how to use it. Just triedAn error occurred while accessing 'Raid-JBOD', the system responded: The requested operation has failed.: Error mounting: mount exited with exit code 1: helper failed with: Failed to read last sector (316335848): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sdc1': Invalid argument The device '/dev/sdc1' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
