it seems to me that dd -conv noerror
should do what you're after, but a quick inspection
of the source shows me that i'm wrong.

i think that could be construed as a bug.

gorka's suggestion isn't quite right, i think, as
you probably do want the cat to terminate when it
reads eof or an error, so something like:

e = write
while(~ $e write*){
    cat
    e = $status
}

might do the job better (untested).
