I was glad that WD kept making them, but I guess at this point there's no shortage of 2nd hand drives out there.
I tend to mess around with old PCs, so I'm glad for having a couple of decently sized PATA drives. I have a 750GB Seagate which I think was the largest PATA ever made, but it's pretty well worn. I actually retired that drive just because I wanted to preserve it.. for what I don't know. My healthiest PATA is a 500GB WD which has only like a hundred hours on it - it was bought for an application that never got much use. Neither is in use right now.
I haven't been using them because I haven't needed that much space on a PATA machine recently. I don't know if the need will ever come up, but there are situations where I'd like to avoid adding adapters or interface cards, so I'm glad to have them available at least.
It's kind of odd how as time went by, the available PATA drives actually got smaller instead of bigger.
I've accumulated lots of PATA drives in the 20-160GB range, and those are the ones I use more frequently. A few aren't very healthy, but I mostly use them for screwing around. Most have different OS installs on them for different "projects" I've messed with on different machines. I've somewhat frivolously ended up with 5-6 different OS installs for a server board I'm messing with right now, just from trying to figure out which install I liked better and how their performance compared.
I'm a bit concerned about laptop drives, because I'd be hesitant to buy one second hand. But I have to admit I haven't actually used my laptop in a very, very long time.
