chkdsk /f /r alternative in ubuntu linux
In windows os chkdsk /f /r will fix a hdd error automatically.
i have lost access in my laptop though i am able to live boot into my laptop using linux.
I have live boot ubuntu 14.04 and i am in a need to run a command to fix hdd logical errors and fix automatically like in windows we can repair using chkdsk /f /r.
So what is the alternative command for chkdsk /f /r in linux in order to fix hdd error?
Solution 1:
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.
Solution 2:
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.
Solution 3:
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.
