sudo mdadm --build /dev/md0 --chunk=64 --level=0 --raid-devices=2 /dev/sdc3 /dev/sdd
mdadm: array /dev/md0 built and started.
morph@morph:/dev$ sudo mount -t ntfs /dev/md0 /media/win
NTFS signature is missing.
Failed to mount '/dev/md0': Invalid argument
The device '/dev/md0' 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?
