I have a iMac G5 with 10.3 installed on it. As far as I know it was running fine and one day my client went to go boot it and i stops at the gray screen with the spinnnig gear. I did try starting it in verbose mode and it appears to hang at "Starting kernel event agent". I don't have any copies of Jaguar so I used a copy of tiger just to see if I could get it to boot. It did and I was able to run a first aid on the disk just to check if there were problems and it wasn't able to finish because there were errors. There is data on this drive that I need to get access to.
