I bought my 3 in early December when Tigerdirect had them on the cheap (with visa card rebates) so I'm passed my 30 days. Like i posted a few weeks back, i had one drive (can't remember which one unfortunately) drop from the array in late January, but I think it was a bad power cable. I replaced it, rebuilt the array and then it was smooth sailing for almost 3 weeks. The array would verify and complete everyday with no issues. Then about a week ago, I started getting about 2-3 of these "warning" messages each day during the auto-verify. I'll call myself "intermediate" in this technology so i came here looking for help. I know how to go run some of these utilities for example, but i'm green on when to worry and when to do what. i'm just looking to learn from the labor of others so I don't toast my "mission critical" cartoon collection.
