Thanks, it is working fine, but even at 7*10ee33 fenceposts a minute, 
will take it a while to get to end end of the files data.  That will be 
at offset about e0000000 I think. Maybe a bit more, but the first gig 
sure isn't blank. I am thinking the file is probably good. And despite 
adding that skip me rule to udev, the source card is being shown as 
mounted on my tde gui.

So how the hell do we stop udev from automounting it?
