Marcus,
I just became aware of a data loss bug for all win8 / opensuse dual booters.
The only "fix" is for users to turn off a new win8 feature. As the ntfs-3g maintainer, I will try to incorporate the patch that blocks mounting of ntfs / fat filesystems if the feature is found to be in use, but that is just a stop gap solution to stop users from shooting themselves. Again, the only real solution is for users to disable the feature in win8.
Is there a way to announce that now instead of waiting for a ntfs-3g security patch?
It is not a security issue, even though it is a critical bug. "security issue" would mean that an attacker could cause damage by doing something unintended. This seems intended breakage. But yes, we should put out updates that somehow detect this and refuse to mount the fs if present. Ciao, Marcus
See below for details of the bug.
Thanks Greg

(someone should forward this to the forums if its not already there).
Just a heads up that win8 introduced a (on by default) feature that can cause data loss for all dual booters. From what I understand, the only real solution is to disable the feature in win8.

There is a opensuse bug:
Bug 798337 - ntfs and fat filesystem corruption with windows 8 systems - ntfs-3g vfat state saved across shutdowns
But the opensuse solution I suspect will just be to fail mount attempts if the new win8 cache file is found.
(I'm the volunteer maintainer for the bug, so I have to research exactly what the best fix is. This affects all versions of opensuse including factory. Once I have a potential fix, I will make a call for testers since I don't have a win8 machine to test with).
