I don't know about a Super Drive, DR JOSE - but the description on Ebay when I bought it read:
CD/DVD R/W drive - which I assume meant read/write.
DR JRand - The SuperDrive is CD/DVD R/W. However, most of the older iMacs came with CD-ROM drives that were CD-R/W, DVD-R. -Which is what my previous iBook had... Which sort of confused me since I also had iDVD, so I thought I could write DVDs too. Nope. However, what it allowed me to do was to transfer DVD content to my hard-drive, and then convert it and burn it into another file type so that it could be burned as a video file onto a blank CDR. Or something like that. So...
-Click on the Apple icon in the top left hand corner of your screen.
-Click on "About This Mac"
-Click on "More Info..." -That should bring up "System Profiler"
-Under the Hardware listing, click on "Disc Burning" -There you will see a listing of the CD and DVD reading and writing capabilities. If you don't see "Disc Burning", click on "ATA". Under the "Model" info it should tell you what kind of disc drive you have.
