Ubuntu: Repair ntfs

Install ntfs-3g with sudo apt-get install ntfs-3g. Then run the ntfsfix command on your NTFS partition.

For example:

ntfsfix /dev/hda6

   ntfsfix v2.0.0 (libntfs 10:0:0)

   Usage: ntfsfix [options] device

   Attempt to fix an NTFS partition.

   -h, --help             Display this help
   -V, --version          Display version information

For newer Ubuntus You can use -b and -d option together. -b tries to fix bad clusters and -d to fix dirty states. So the command can be

sudo ntfsfix -b -d /dev/sda6

--help shows them
