    Hi...could use some help. I was trying to upgrade my mini G4 from a combo (mod CW-8123) to a super (UJ-845)drive...Coincidentally, a disk had gotton stuck in the combo just before I was going to do this...the first time in 2 years...just wonder if something may be related...Anyway I got the disk out and retried the combo drive and it works fine again...But I couldn't get the superdrive to work...In fact, the mini won't boot with it in..its as if it is trying to boot from the superdrive maybe....get the folder and ? not the apple (use OS 10.3.9)..I also tried a few other combo drives I had lying around (also 8123 and they do the same thing). Are all these dirves bad? or is there some master/slave setting (didn't know there were on these) that is causing trouble or something else...The superdrive was bought used but the guy said it worked fine/was tested...the other drives I'm going to check in my ibook to see if they work there..but any ideas appreciated..thanks, rick

    I replaced a busted Superdrive on my PowerMac with a old ASUS DL DVD burner I had laying around the house. It worked fine and was recognized right away, but I had to install Patchburn to support burning capabilities in iTunes.

    From what I understand you should be able to simply replace your combo with your Superdrive and your mini G4 should at least see it and boot. Unless there is a problem with your Superdrive. Have you confirmed the Superdrive you have is good and it works?

    You can also check this drive compatibility database to see what Superdrive models other folks have been able to use successfully in their mini G4s.

    compatible but not booting

    Yes I believe the combo (CW-8123-C) and super (UJ-845C) drives are compatible 'apple' drives made by Matshita/Panasonic...unless the letters after them have to do with master/slave or other settings...So I am still miffed...I have used these combo drive models in upgrading iBook Clamshells (cutting a nice slot in the bezel) and they work great...and bet they are not broke and will..I will try them soon...but just wonder what is up with upgrading in the mini....gone back to the original CW-8123-A that was in there and works fine for now..Any further insight or suggestions regarding getting especially the UJ-*45C superdrive to work in the mini appreciated, and could it be a master/slave thing and can one reset that somehow (hardware or software?)...thanks, rick
