Actually you only need to open it for write, I usually use:

	true > /dev/da2

The problem here is, quite simply, that nobody tells GEOM that a card
has been inserted.

opening for a write and then closing it forces a retaste because metadata
blocks could have been written.

The correct fix for this is to have scsi_da tell geom that the card
was inserted.
