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?
In windows os
AFAIK there is no full replacement for
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
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.
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.
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.
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.
Use "fsck" : http://ss64.com/bash/fsck.html
fsck -a /dev/sdXY (sdXY is the "partition" or disk that you want check).
