Hey guys, So I recently bought a new optical drive because mine had died out a long time ago and was making plans to upgrade to snow leopard (currently running 10.4.11) So I installed it and everything and everything seems to be going right (hearing the disk spinning) so I tried a dvd with it and nothing came up, went to system profiler to ata and burning, and they found nothing. Perhaps a misconnection on the resemble? Also I noticed if I hold my eject button its to no avail as well. Either way I'm gonna open her up later on tonight and double check. But any ideas? My old model was a UJ-857-C and I put in a UJ-867.
