my Volume access control minifilter causes USB mass storage eject to fail

Glad to be able to help.

Peter

I mean, Is this write-protected queries conversation valid in FS minifilter context? How can I intercept such query in a minifilter?

Thanks again for helping me out!

I am not an expert in PnP but I’m pretty sure that you want to let everything go down.

You cannot just blindly stop all writes to the volume

You know you’ve just replied to a thread that’s a year old, right?

I dunno, but I suspect that the OP isn’t still worried about this issue :wink:
