Hard Drive Size Limitations



Pardon my ignorance. I am a PC technician that has only touched a MAC once and that was to pass a MAC notebook from one person to another. I was just asked to upgrade a G4 that is being used to record audio. They needed more RAM and a larger HDD. I opened up the unit and saw that it is using DDR PC2700. Easy money, i went out and grabbed a stick of 512 DDR PC2700 Cas-2. The hard drive looks to be a standard IDE Seagate drive. I purchased an IDE ATA/100 160GB hard drive to run as a slave. Here are my questions:

1.) Windows has a limitation of only seeing 137GB otherwise you need to use a PCI card or set up multiple partitions on the drive. Do MACs have any similar limits?

2.) The motherboard (operating on my memory now b/c it's not in front of me) had a couple of extra IDE connectors. One was labeled 33 and the other 66. I was under the impression that this referred to the ATA though I have never seen a PC board with different speeds on different ports. Toward the other end of the board was another IDE connector and the Seagate was plugged in there. It however didn't have a label as the others did. Can I use a standard 80-pin/40-connector cable to set up master and slave to the IDE that the Seagate is already on or do I need to utilize the connectors labeled 33 and 66?

Any help would be greatly appreciated. I'm sorry if you need more information on the setup. I opened the case and looked around for about 5 minutes and that was it. I do believe it was this MAC http://docs.info.apple.com/article.html?artnum=75343 but again there are 2-3 that look very similar and not working with them before makes it hard to distinguish between the characteristics.

I believe that Mac will read any size (in os9 or osX)

#2... I don't think will work.. u might need the 33 66.

I am no expert in any of these areas, but this is my best guesses.
