text: i have a "cd-writer" and a "dv-rom" drive on my computer. to install a "dvd drive", which should i replace? my point is this....can a "dvd rw drive" do everything a "cd-writer" and a "dvd-rom" do?   i don't have anymore room. i must remove one of the two drives (either the cd-writer or the dvd-rom drive) that came installed on my computer in order to install my new "dvd rw" drive. bottom line, does it matter which drive i remove to make room for the new dvd rw? replace the cdrw because the dvd writer can burn cds if your pc is fast enough you can copy from the dvd to the dvd&#92;rw
