    Sata Cable help
    « on: November 03, 2008, 10:37:52 PM »
    SATA Hard Drives have two cables one for Power and one for Data.

    When I look up how they work on the web I can't find what I need.

    Is the SATA Data cable 15 pin and if so when I see a picture of one it ony has 4. wire out of the back???

    And what does the Power cable look like and the Color codes for the wires.

    I seem to get the run a round on the web??

    Sata power cable and pinouts are shown on this site.  There can be 5 cables, or 4 if the +3.3v is not required, and there are 15 pins..  Please read....

    Sata data cable has 7 cables and 7 pins and is shown here..

      NO, IT IS NOT THE DATA CABLE.  AS I STATED, IT'S THE POWER CABLE.

      What you are missing is the ability to read....

      Pinouts are:
      pins 1, 2 and 3        +3.3v        cable color Orange
      pins 4, 5 and 6        Ground      cable color Black
      pins 7, 8 and 9        +5.0v        cable color Red
      pins 10, 11 and 12   Ground      cable color Black
      pins 13, 14 and 15   +12.0v      cable color Yellow

      The site I already linked has all the info you want and has lovely color photos of cables.  Did you not read the site as requested?  If not, why not?

      Here are a couple of quotes from the site:
      Quote
      SATA was introduced to upgrade the ATA interface (also called IDE) to a more advanced design. SATA includes both a data cable and a power cable. The power cable replaces the old 4 pin peripheral cable and adds support for 3.3 volts (if fully implemented). The connector is shaped so it can only be plugged in the correct way.

      You have to be careful about SATA power cables. Some of them are missing the 3.3 volt wire. People with older power supplies often use adapters which convert from 4 pin peripheral cables to SATA power cables. But since 4 pin peripheral connectors only supply 5 and 12 volts, the SATA connector is missing 3.3 volts (there's no orange wire). There are also a few older power supplies which inexplicably have SATA power cables which are missing the 3.3 volt wire. Currently, SATA drives rarely use 3.3 volts. That may be because there are too many people using adapters so the drive makers don't want the headaches which come with using 3.3 volts. But in the future, 3.3 volt drives may become common so you need to be careful when using SATA power cables which don't implement 3.3 volts.

      If you still have questions for goodness sake READ THE LINKED SITE

      Edit: Because you seem to be too lazy to look at sites I've attached a picture from the linked site.

        Ok if the Power Connector for SATA has 15 Pins why does it only have 5. Wires going into it?

          because the connector is simply being used as a splitter, look at the power connector pinout diagram.

            Ok so the SATA Power Cable has 15 Pins but 5. Wires because every 3. Pins goes to just one Wire RIGHT??

            And once again, a simple query is approaching becoming a multiple page memoir simply because the OP lacks the ability to perform logical deduction...
