[root@localhost robbins876]# mount /dev/dm-0 /media/windows/ -t ntfs
NTFS signature is missing.
Failed to mount '/dev/dm-0': Invalid argument
The device '/dev/dm-0' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
