Hi Jeremy,

Yes if we could get a patch for this that would be great.  And let us know when you think the patch will be available.

Thank you for your quick attention to this.

John McCarthy

Ping me if you need a patch for this. Shouldn't be hard to change from the old SMB_COM_QUERY_INFORMATION_DISK
SMB1 command to the trans2 version for SMB1 connections.

Shouldn't be a problem when using SMB3 connections.
