I have a beige G3/266 tower which has in it the original internal 6GB IDE drive in the top rear bay.
I just bought a new 20GB drive to replace the 6GB, but I need a way to transfer all the data from the 6 to the 20.
Does anyone know if it's possible to hook the 20 (temporarily) up to the ATAPI IDE interface that the CD-ROM drive is currently on (which would necessiate temp. removing the CD)? Isn't ATAPI a subset of the IDE spec? Are they pin compatible?
Any advice on this would be much appreciated. -Omni

P.S. Looking at Apple's Dev. documentation for the beige G3's, (http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-G3/PowerMac_G3/PowerMac_G3.pdf) a diagram of the logic board indicates that there are two IDE buses: IDE0, to which the internal HD is attached, and IDE1 to which the internal ATAPI CD is attached. Does this mean there are two IDE controllers? Do they support master/slave, so that I could hook up an extra IDE HD to one of them?

P.P.S. What exactly is master/slave? does it have anything to do with start-up order or OS bootability?
