lucas@inspiron:/$ sudo mount -t ntfs  -o uid=1000,gid=1000    /dev/sda2   /data
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
