Description
When an external NTFS hard disk is not cleanly unmounted because you unplugged it wildly on Windows, or because of a Windows crash, there is an error when you try to plug it on ubuntu, explaining what to do on the command line.
There should be an easy way to mount the volume anyway, by giving the choice to the user to mount it anyway, or not to mount it. A clear dialog box should do the trick.

I use a desktop, not a laptop. Instead of shutting down, I hibernate Windows. After this Ubuntu cannot mount my ntfs volumes. I tried to edit '/etc/fstab' file, adding option to remount the volumes as read-only in case of errors:
# /dev/sda1
UUID=CAD851F2D851DCEF /media/sda1 ntfs defaults,umask=007,gid=46,errors=remount-ro 0 1
But it didn't work

I think this is linked to the ntfs-3g drivers which refuses to mount "unclean" NTFS partition.
I will only mount the volumes once Windows has checked the filesystem (chkdsk), then mounted them once.
This is done as a safety measure to prevent data loss dues to incorrect filesystem structure.

yeah, sometimes I boot ubuntu Live CD to rescue some files because of windows failure/problem, but since windows failed, the drive not usually properly unmounted!
If ubuntu detects that the filesystem is "unclean", it should say: "There is a problem is the filesystem! it is unsafe to mount, because data mey be lost! do you want ubuntu to correct the filesystem?" if clicked yes, then automatically run some script/program to "repair" the filesystem and mount it...

you should NOT EVER hibernate one OS and then start another one. hibernation can leave the file system in an unclean state (since it just dumps RAM to disk, which may include cached writes that haven't been committed yet). That's why you can't mount your NTFS volumes, and it's really for your own protection.

p.s. you can also add the -force option to mount them anyway. But as flip said, do not ever mount a partition from a hibernated OS. You'll screw up your files on it.

I have the same problem often - when hibernating. Since I have several Windows partitions with lots of data, I would very much appreciate a "mount as read-only" possibility. That should be safe to do, no?
It would sometimes even help just to be able to read the directories on the Windows partitions to check file names and versions.
I support the suggestion (READ-ONLY).

I have this problem regularly with USB thumb drives that I share with colleagues. Comment from them: "In XP you don't have to disconnect the drive before removing it."

Actually a can mount. An I mount my ntfs volumes as read-only. It's just annoying to do this manually.

I confirm this inconvenient.

@wanchai: It's uncommon to have NTFS formatted USB thumb drives. Have a look at http://brainstorm.ubuntu.com/idea/689/ for a (likely) more relevant idea to your problem.
@K-Man,blindvic: Read only may be safe (I don't know for sure), but it can still leave files in a state that the users won't expect them to be in. ie, edit a file in windows, hibernate, open file in linux, wonder why your changes weren't saved, restart to windows, wonder why the changes ARE there. I'm not sure this is good default behaviour, it's better not to mount these partitions by default in any way.

But that should be readonly, or there may be data destruction.

@sf_007: I think the problem is that there is no such program for linux.

the trouble is even a read only mount on an inconsistent file system can lead to unpredictable results. the filesystem should be checked and fixed before mounting.
however, in the case of a hibernated drive running a checkdisk on the filesystem could have catastrophic effects when going back into the OS that you hibernated from.
I'm not sure what's best to do here.

if Idea #5978 is a duplicate of this then this idea is a duplicate of #689! who moderates this stuff? they should have to explain why something is a dup and not a dup.

Hey all,
> you should NOT EVER hibernate one OS and then start another one. hibernation can leave the file system in an unclean state (since it just dumps RAM to disk, which may include cached writes that haven't been committed yet). That's why you can't mount your NTFS volumes, and it's really for your own protection.
First, my USB 500 GB drive is NTFS (I recently switched to Linux). I want to have the option, clickable rather than command line, to mount the drive. Whether this is unsafe or not is the user's business. If it is unsafe, warn them and then let them mount it. Otherwise, the system seems broken rather than protective.
