Hey, I recently picked up an iMac G3 for $100, first off its a great little machine but with one problem, a noisy hard drive. So I dug around in my spare parts for my servers and found an extra 80Gb IDE drive that worked. I wanted to install it in the imac but there is major problem, the fact that I have to re install OS 9.2.2 to install OS X. I dont have the install cds that came with the computer, so I thought that I can just use a program like Carbon Copy Cloner to clone the main hard drive onto my Western Digital MyBook 600Gb External USB drive and put the new hard drive in and copy it back over. But for some reason the external HDD doesn't show up on the imac (It shows up on my Mac Mini, but not the iMac). After a while it sometimes gives me a drive error message and tells me to initialize the drive, no problem. I go to erase it but I am only rewarded with a "Input/Output error" message every time no matter how much I try. Why wont the external hard drive show up on the iMac?
