BUG: dead freeze

[un_pogaz]

I'm encountering a critical and very annoying bug.
FFS freeze. But not a simple freeze: it's a major, critical, dead freeze!
Not only FFS does it no longer respond, but even trying to kill the process don't work! This can even severaly impact the shutdown and delay it by several minutes.

The most frustrating thing is that it seems to happen quite randomly.
I suspect a issue with the external drive (NTFS), but it's impossible to be sure and I don't want to reformat my drive unless it's absolutely necessary. Especialy that it occure only now and that the previous version of FFS worked fine.

Here the the various case I have determined:
During the comparison, if it takes too long to read the files, can freeze at any moment and garanted freeze when come to the step of comparing the pair to sync (can be bypass by cancel the compare and manualy split of sessions of 2min).
When sync, randomly (can be bypass by watch and cancel if a file take longuer that except to be sync (if occur on a .ff_tmp file, is over, even cancel it will freeze)).

Version: 14.9
OS: linux, arch

EDIT:
looked with some diagonstic tool, I get this report.

ERROR: NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.

Will see if I can fix it from Linux only.

Corrupted filesystem causing FFS to wait indefinitely for an operation to finish. Not a FFS issue

Yeah, I see this outcome after get the diagonstic of the drive.
Shame for me, but at least This will let me do something a little fun with the drive formatting.

However, that FFS fail on corrupted filesystem is perfectly understandable and make sens to me. But it would be nice to make FFS more robust again such thing and abort the operation, rather to wait indefinitely that it finish, to the point to impact the shutdown... that it a real issue.

That's a windows issue. It would make no sense to break drive functionality in Windows by creating your own drivers for file system access. FFS isn't what's stopping a shutdown, it's the storage operation request that Windows made that is stopping it

And so, FFS that freeze is merely the visible symptom of a much more serious problem and external to FFS, and so irresolvable. Get it, thanks.
