DISM Apply the FFU image of the DVD player

When I apply the ffu from the file located on my DVD drive (next to the bootable PE disk), I get the following error message:

DISM / apply-ffu /ImageFile=Y:img.ffu /ApplyDrive=\.PhysicalDrive0

Error 1
Incorrect function

But surprisingly, when I simulate, he reads in network, he can process the same file.

net share y = Y:  / GRANT: Everyone, READ
DISM / apply-ffu /ImageFile=\localhostyimg.ffu /ApplyDrive=\.PhysicalDrive0

Application of the image
[==2.0%                    ]

Is DISM a bit unfortunate to read from the FFU from the UDF file system? How can I solve this problem?
