I don't think I have enough information to do it.

It says the stream is seek-able because it thinks it is a normal file it 
is opening, but seeking do not seems to work on devices.

But if I send the data  directly to the FileStream using the 
Write-function it works, but I have problems reading the data from the 
stream.
