Recently I have been having 18 seconds image freezings on one of my 4TB Seagate HDDs, and I wonder if it might be announcing something drastic is going to happen. As I have two similar Seagate drives, and the problem seems to be happening in just one of them, I wonder. The program I use to check my HDDs is Crystal Disk Info, which has proven quite reliable, but I wonder if there's other non-destructive way I can test my HDDs with. Now that I think of it, perhaps I am completely wrong on my assumption because the day before yesterday it happened when I was playing an HD DVD on my computer, and the video came through the ethernet network, as usual, played through my Mede8er media player. That things froze for 18 seconds it's a fact, also that it happened about 3 or 4 times.
