DVD Ram useage

I have a LG 4040b multi writer that does ram too. How exactly do you use rhe ram function, i can format it under xp and seem to be able to copy files to and from it but there is a message that says files ready to be written to disk at the top of the window and a down arrow in the corner of the files ? Also with a ram disc in my computer says its a cd drive yet the icon next to it says dvd ram ? take the disk out and the txt says dvd ram drive and the icon just has a cd type icon with no dvd written on it unlike my pioneeer dvd rom which had dvd on the icon ???
