ntfs corruption: chkdsk or not?

Weapon S · 09-29-2012, 03:39 AM

Linux froze while doing a disk intensive operation on a ntfs partition. Things were messed up. (Tried all the sysrq combo's.)
Normally I'd run Windows' chkdsk, but there are some Linux partitions on the disk as well. What should I do?
I did run chkdsk -f, but not yet a second time, as it reported "unallocated space" on my drive. I have tried searching the forums without results. ddg.gg turned up ntfsfix. I guess that is safer, because it is Linux aware. Should I still run Windows chkdsk?

Have you tried "fsck"? It is chkdsk but for Linux. Also, you should *NEVER* run fsck when the disc is mounted, instead, you should get a live-cd and run it,

So, for example, your linux partition is /dev/sdb1, type this on the command-line:

Code:

fsck /dev/sdb1

It must not be mounted and you have to run fsck as root.

Or if you really have no choice about getting another live-cd just for that, you might want to add the file "forcefsck" to / on your linux OS with:

Code:

touch /forcefsck

on your command-line as root.
After that, reboot.
