Actually, the "click of death" that got me was from Zip drives, pre-dating the era of common external hard drives. It was my way of saying that I don't expect *any* external media to be reliable.It turns out the click of death issue affected the "Expansion" line, not the Free Agent line.
Funnily enough, the two 4TB drives I have sitting on my spares shelf (I always keep a hard drive or two in the box in case one of mine dies) are Hitachi. I'm sure I bought on price so that chart is nice to see.
My work required 7 random overwrites followed by basic physical destruction. Glass platters made that last part easy to do indoors, in the office, without making a mess. Anything with metal platters, well, we had one guy who liked to make sculpture out of the internals. Personally, I like the old "Put 'em on a stump and slice 'em with an axe" method that I use at home.And Ben, all of our work HD's get decommissioned with one shot with a BFH.
