Plants, however, need much more water than many living things because plants use much more water than most animals. Plants also contain more water than animals - plants are about 90% water. The amount of water a plant needs depends on the type of plant, how much light the plant gets, and how old the plant is. When plants are not watered properly they wilt. This is because of something called turgor, which is water pressure inside the cells that make up the plant's skeleton.
I'm going to assume that this is a USB drive. If the drive shows up under Device Manager, but does not show up under My Compuiter, right-click on My Computer and select Manage. Click on Disk Management. In the center column, bottom pane, you will see a list of all storage devices (labeled as Disk 0, Disk 1, etc).
