WeaponX 0 Report post Posted December 14, 2005 Back to the old question mark on disk problem. I replaced the whole hard drive on one of the sites I was working on. Then I installed Mac OS 8.6 on it. Restarted and the question mark on the disk came back up. Thought the install went bad, so I tried initializing the drive again and installed OS 9.1 on it instead. Still the same problem.Is there anything special that I need to do after I finish the install? This is what I did today:1. Replaced hard drive.2. Popped in Mac OS 8.6 CD and initialized the drive.3. Installed it successfully (erase/format and install).4. Restarted and took out the CD.Then I had the question mark error again. So I zapped the PRAM and also reset the NVRAM. Doesn't seem to help. One thing I didn't do is hit the CUDA reset button on the logic board, but I don't think that will help.So what am I doing wrong here? I had to bring it in the office to get it fixed. They just said OS 8.6 was reinstalled. I'm sure the install CD I have it not corrupted as I recall using it without any problems before on another iMac.Thanks.
