How do i use ubuntu fixing ntfs file system?

Use apt-get from the terminal to install the ntfsprogs package - sudo apt-get install ntfsprogs

Then you can use the tool ntfsfix from the terminal to attempt to repair a ntfs partition.

Example:
* unmount the drive if it's mounted already
sudo umount /dev/sda1 - read below for device naming info
then type: sudo ntfsfix /dev/sda1

Note:
A typical home pc or laptop has 2 or 4 IDE channels as follows:

• ide0 = primary
• ide1 = secondary
• ide2 = tertiary
• ide3 = quaternary

For example:

• ide0 = primary master = hda
• ide1 = primary slave = hdb
• ide2 = secondary master = hdc
• ide3 = secondary slave = hdd
• sata0 = 1st sata device = sda
• sata1 = 2nd sata device = sdb
  

and so on...
SCSI & SATA devices are listed as devices sda, sdb, sdc, sdd, sde, sdf, etc. in the /dev directory. Similarly, partitions on these disks can range from 1 to 16 and are also in the /dev directory.
Now each hard drive has 4 primary partitions (limit of PC x86 architecture). First partition is denoted by number 1. For example:

• First partition : /dev/hda1
• Second partition : /dev/hda2
• Third partition : /dev/hda3
• Fourth partition : /dev/hda4
• sata0 device, 1st partition: /dev/sda1
• sata1 device, 1st partition: /dev/sdb1

And so on.
You can run command fdisk -l (lowercase L) to display a list of partitions:

WARNING! These examples may result in data loss. Use fdisk command with caution as it can manipulate / overwrite your partition table.
