I was just moving a HDD to the Zip drive slot on my Power Mac G4 Digital Audio. The drive sled is a really great idea on paper, but not in practice. So, I read the "Replacing Zip Drive" article from the KB. Then I tried to take sled out, but the shiny guard on the back of the optical drive got stuck. So I ripped it out finally and the HDD slotted in easily enough. Then I found out that the slave bit of the power cable (P6) wouldn't work because it was too short, so I pulled up P5, and connected it. Finally, I found out that the IDE cable wouldn't work because my HDD's connecter was on the left, and the optical drive's was on the right. And all this in a space so cramped I could barley fit my hand in. I pulled out the whole sled and removed the HDD, and put the sled back and put the HDD back. I reassembled everything, and it all works. That's the least ergonomically designed computer I've ever worked on. What do you think Apple's least ergonomic design is? And what is the P5 cable for?
