I am just wondering, are all of notebook's drive are the same size? I am asking this because I thinking to upgrade my notebook's cdrw/dvd combo drive to dvd-rw drive. I know some notebooks may require for you to remove the fateplate of the old drive and put it on the new drive, thats no problem for me.
The Dell uses a standard 12.7mm drive. Only ThinkPads and a few others use the super slim drives to help keep them thin. Another option would get an external desktop drive which will offer better speed and quality unless you are planning on burning while on the go.
