I've got some of the cables like in your links. I was hoping they made a little short thing like in your second link that I can plug into the drive then plug a SATA power connector to but it doesn't connect pin 3 to anything. It stays SATA basically, no molex needed. To be honest, I only have 4 wires on my power cable going to the SATA connector. The ones I see with the 5th wire are the ones with PWDIS. Thing is, I'd don't know how it is connected inside the connector. From my understanding, the 5v wire is connected to several pins including 1 through 3. That's what makes it not work. I think. That may vary from one power supply maker to another and may even vary between models of the same maker. In a way, that sounds interesting about the new way. For those who like to show off their rigs, they would like that because it would result in less cable clutter. To be honest, I'm not against the PWDIS feature. For some use cases, it is a good idea. It just should have been made backward compatible. Right now, I have one case with about 10 drives in it. I'd like to be able to disable a drive before unplugging it. If my system supported PWDIS, I'd sure use it and be glad to have it. My new Fractal case holds 18 drives I think. I can add cages which may make it hold even more drives. Having the PWDIS feature would be nice. I could unmount a drive, disable it, then unplug and remove it and be almost the same as doing so when the system is shutdown completely. It's a good idea, just needed to be implemented better. For those following this, the hard drive made it back to the seller. When they tested the drive, it was bad. They got the same as I did in the very old rig with the molex to SATA cable. I suspect it was a drive with the PWDIS feature and it turned out it was also bad. I did order another drive. I ordered one I got before that works but I also included a note that if the drive has the PWDIS feature, to cancel the order and let me know what drives they carry that don't have that feature. I just wish there was a very easy way to find out which drives have the PWDIS feature and which ones don't. I'm beginning to wonder if there really is a way other than plugging it up and seeing of it comes on. All this because they didn't make something backward compatible. o_O Dale :-) :-)
