I went back to ebuyer this evening, and it's obvious I swapped from one read-in to another on the point of purchase. I recall I was having problems with that dumb Barclaycard final security box that undid the entire purchase. When I went back, I successfully purchased . . . another drive.
It's not worth the footle of sending it back, so I'll just have to find a place for it. I've no need for a network drive - my last one, a Black Armour - packed up just as we were selling up in Texas. Fantastic timing, since my main PC's HD didn't survive the Dallas security. It would have been better off as hold baggage since it's thought they don't like the magnetism from the scanners' belt motors. Yes, backups 3 and 4 saved the day.
So, the SSD stays and the RED holds my chaotic mass of photos etc.
I was going to use that first 1/3rd during the transition to a new W7. (64bit this time.) so it is a bit of a disappointment from that point of view. If I change my mind again, and go for a new HD, what's a good, fast, reliable, 1 TB HD that fits that bill? When asking this question some years ago, the industrial quality units with good write-ups were 5 times the price.
