Hi all, I have 2008 Mac Pro (not early one but later 2008) and found that the DVD-R/RW drive is slightly broken. The tray won't be closed fully and dvd is not recognized. So I have to manually push the tray so that Mac Pro will recognize the disc. Plus I have to use the command line drutil eject tray 1 something like that.. to eject the tray. My question is, can I replace the dvd-R/RW drive to any brand new internal DVD-R/RW drive? Is there any compatibility issue for that? Thanks for your replies!
