AFAIK there is no full replacement for chkdsk. You basically have two options

• use ntfsfix

ntfsfix is part of ntfs-3g and should be pre-installed on your Ubuntu LiveMedium. It can fix only some fundamental issues with NTFS, but it always triggers a chkdsk on next Windows-startup.

In some cases this can be enough to get it back to a usable state (dependending if Windows can boot far enough to be able to run chkdsk...).

If this fails, you are left with option Nr 2

• use a Windows install/recovery CD/DVD/BootStick

from there you can run chkdsk from a commandprompt.

If you don't have any Windows-media available, you can also remove the harddrive and connect it to some other Windows-maschine.

Linux has no tools to fix NTFS file system.

DO NOT use ntfsfix for fixing your disk. It just removes "dirty FS" flag and you get a false sense of security. After a couple of "fixes" your data becomes unrecoverable.

Do use Windows. Either have a separate HDD with Windows, or install VMware, download Windows vmware image from Microsoft, share raw disk with guest OS and check it from there.

Although it is not as powerful as Windows' chkdsk, you can use following approach:

sudo ntfsfix /dev/sdXY
sudo ntfsresize -i -f -v /dev/sdXY

After that you will be asked to do it in Windows anyways as Linux doesn't have a powerful equivalent, but this can do a good job.

The ntfsresize command above will check for bad clusters and do a filesystem consistency check.

EDIT: Some people are reporting problems that arise with the use of ntfsfix so refrain from using it unless you have no other option as it may cause data loss.

Use HBCD. It has a windows interface, as well as windows kernel. You can use CMD (CHKDSK) there.

Use "fsck" :

fsck -a /dev/sdXY (sdXY is the "partition" or disk that you want check).
