I have a G5 2.3 dual \ 6 gb ram \ 2 TB HD \ Tiger 10.4.3. and it seems the more i use the CD-RW to listen to music or record my CD-RW starts to act strange. Sometimes when I hit the eject button on the keyboard it opens and sometimes it dosent. Other times I hit the eject key and it opens real quicky and closes before I can get the CD out, then when i press the eject key again, then it opens and stays open long enough to get the CD out. I swapped out the drive twice with other CD-RW drives that came out of other G5's and they all do the same thing. Whats up with that ???!!!
