Thanks so much! I was aware this was peer-to-peer, but not that this was the home vs. computer business section. I'm new here, so thanks for clarifying that.
I have a Seagate drive. It's already installed and I can't see any labels on it. However, I have the box. It has other symbols on it, but no AF. There is nothing to suggest it's AF: nothing in the literature that came with it, and nothing on the box. This is the drive:
So it looks like AF isn't my problem. I will re-post in the business section and see if anyone has any ideas. Meanwhile, I'll plug in that drive so I can see what's going on with partitions now that I've tried to reformat and install a few times.
Thanks again ... I appreciate your input.
