Answer: 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.
