File attributes not preserved on copy

    I am working on a filesystem driver. I have a weird problem while copying
    files from an NTFS volume to my volume.

    After the file is copied, Windows sends an IRP_MJ_SET_INFORMATION IRP with
    FileBasicInformation information class. Now the attributes field in the
    FILE_BASIC_INFORMATION structure is always zero even if the original file had
    read only, archive and/or hidden attribute set. So the file attributes are
    not preserved on copy unlike a copy between two NTFS harddisks or to a floppy

    Is this expected behaviour? Is there anything the filesystem driver needs to
    do during driver startup or volume mount to ensure that Windows sets the
    right file attributes on file copy? Any information is greatly appreciated.
