The Generic-mmc-raw driver is trying all available raw writing data
block types so I don't think that the problem is here. Maybe the
driver does not support write simulation in raw mode. You should
play with all mode page setting which are altered in 
'GenericMMCraw::setWriteParameters()'.

However, all drives that support the raw writing mode work with the
generic-mmc-raw driver so I'm not sure if the Teac recorder really
supports this mode.

You'll have to modify "ScsiIf-lib.cc". Look for a line like
'impl_->scgp_->verbose = 0;' and set the verbose level to 1.
