Using Cards
The computer recognizes the memory card and automatically loads the
appropriate device driver. If the configuration program tells you to load the
manufacturer's drivers, use the media that came with the memory card, if
applicable.
Removing a Memory Card or Blank
CAUTION:
Before you begin any of the procedures in this section, follow the
safety instructions in the Product Information Guide.
NOTICE:
Use the memory card configuration utility (click the icon in the
notification area) to select a card and stop it from functioning before you remove it
from the computer. If you do not stop the card in the configuration utility, you could
lose data.

partially ejected, remove the card.
