I recently acquired an iMac G3 (slot loader) and I am trying to install Mac OS 9.2.1 on it. OS installer seems to boot to Mac OS just fine. The problem is when I try to run the installer, it doesn't detect any volumes (as if there's no hard drive). Disk utilities also don't detect a hard drive.
I opened up the mac to check if there's a hard drive and there is. I also unplugged and firmly plugged back in the power and ribbon cables going into the hard drive. In addition, I removed the cmos battery for a minute, then placed it back in the slot where it should go.
I tried installing again after doing all of these things and the disk utilities and installer still don't detect the hard drive.
Do I need to replace the hard drive? Could something else be wrong?
