More unique is impossible as unique means one only. |

More unique is impossible as unique means one only. Useful though - my house is one of four that are 'identical', but there are small differences, e.g. Where I put a large loft-hatch in my house would be impossible to do exactly the same next door due to a major joist being about an inch along. This means that each of the four is unique (in more than piffling details) but the one with two rooms knocked into one is 'more' unique. It's the difference between 'hard' terminology (which should always be used for technical subjects) and heuman 'fuzzy' terminology. That's why computers will never quite manage to be like us, although the Turing test was passed many years ago, when 'help' lines were first 'manned' by automata indistinguishable from computers.

[snip] No, both power connectors work. But the recommendation is not to connect a SATA 15 pin and a Molex 4 pin at the same time. And the "corner case" for this is so obscure, it's hardly worth mentioning. Normal I/O looms will be using the same 12Vn output for powering drives. All the power will be coming from the same 12V and there won't be a loop. There were a few supplies with four independent 12V transformers inside. This would give a 12V1, 12V2, 12V3, 12V4 supply. It was very confusing as to which supply went where. The owner of such a supply, was well advised to find a block diagram of the looms, and make sure it was understood before installing the supply. If (somehow) one drive power source ran off 12V3 and one off 12V4, you wouldn't want current flow between the two connectors, because it could burn something (burn the pins on a connector). It's for that obscure reason, you're not supposed to plug in the SATA 15 pin and the Molex 4 pin on a drive like that, at the same time. The chances of that happening are pretty damn close to zero (cross-flow). Now, a person *could* put two separate ATX supplies in a machine, and run 12V from one supply to the SATA, and 12V from a second supply to the Molex. So that's another way you could encourage cross-flow. Paul |

Just get a molex-sata adapter cable: https://goo.gl/JZWkGY https://smile.amazon.com/Power-Cable...+adapter&psc=1 Which I and others already previously mentioned. I only replied in THIS subthread to Char's inquiry about SATA drives with Molex power connectors. |

Why I mentioned that only ONE of the power connectors should be used on those SATA drives. BOTH are usable but use only ONE. Besides, there is no value in using both power connectors at the same time. I suppose some noobs would see an unused connector and just must fill it. |
