That's good to know. I will definitely look into and test fsck.ntfs
from ntfsprogs-plus.

Regarding our use case, our primary scenario involves USB flash drives
and external HDDs/SSDs for data exchange between Linux and Windows
systems. In fact, we are already users and beneficiaries of your work
on the exFAT driver in many of these scenarios. Therefore, our main
concerns are:

- File copy performance for typical user operations.
- Filesystem consistency in the face of unexpected actions, such as
  users unplugging the drive without safe ejection. This is where we
  believe journaling support would be crucial.

We are currently preparing to test the ntfsplus driver ourselves. Once
it's merged into the mainline kernel, it's highly likely that we will
provide support for it in Deepin as one of the early adopters.

Please feel free to let us know if there's any way we can help, be it
testing specific features, providing feedback on real-world usage
patterns, or otherwise. We would be happy to participate.

Thanks again for your work on this and for keeping us in the loop.
