    Right click my computer > manage > on the left side, double click disk management and you'll get a popup window that you can format from.

    I did this recently too, formatted fine, but it kept showing as a SCSI CD-rom device. What's up with that? I uninstalled it, but it always reinstalls on startup up. I just ended up disabling it in the device manager.

    Also is it better to have it a a slave to my main HD or a master on its' own channel?

    All sata drives have their own channel, so there is no "master" setting.

    The only thing you may have to do is make sure your bios is set to boot to the main drive first.
    Typically though, it will automatically boot to the drive with an os.

    Everythings been working fine I was just wondering if there was really any performance difference. :)

    incorrect.

    There is only 1 drive per cable, but there is still a master/slave primary/secondary relationship at the controller level.

    Which is 100% irrelevant to the question at hand.

    Yeah, when you go in the bios they are still using the term master.

    But on the drive, the slave master setting that was ONLY RELEVANT to drive and cable itself, EVER, in the first place, IS GONE.

    Period.

    WRONG. It is PERFORMANCE-AFFECTING!

    Only if they're using ATA emulation.

    wtf? there is no master/slave relationship in sata.
    each connection in the controller is a dedicated host. each drive or device is a master. they are not sharing anything.

    you are probably thinking about a motherboard having a "primary" SATA controller on the southbridge and a "secondary" SATA controller like Jmicron or a RAID adapter.

    you are wrong again.

    Running in AHCI or RAID mode (which is the mode most commonly used with Windows XP and Vista) the board will utilize only 1 controller to drive 6 channels of SATA. This results in a traditional IDE-style interface, where the master/slave relationship is extremely relevant. You still obtain improved performance when compared to a PATA-133 interface, but it will be less than that of drives operating independently.

    You CAN operate in NATIVE mode with certain configurations requiring specific hardware configuration, drivers, and supporting OS; this would also require forfieting benefits of NCQ, Hot-Plug, Async Sig Recovery, ATAPI Async Notification, and Host&Link Management (All require AHCI, which would disable the secondary controller, and force drives into the master/slave dillema). This is why most people do not run in native mode.

    When using a quantity of drives to which the equation N <= C (where N is the quantity of drives, and C is the number of channels supported by the primary controller) you will realize a performance benefit to ensure that drives are placed on the "master" position for each channel. This is most-often interfaces 0 & 2, however it can vary.

    As such, assume that you have 2 drives utilizing AHCI drivers in a compliant OS.
    Assume that interfaces 0 and 1 were primary and secondary, respectively, on Channel 1, and interfaces 2 and 3 were primary and secondary, respectively, on Channel 2.

    Drives on interfaces 0 and 2 will out-perform a similar system with drives on interfaces 0 and 1.

    :confused:

    Traditional IDE-style interface = on one cable, Slave asks permission from Master to transfer data, if Master is busy, Master tells slave to wait, if not, proceed.

    Besides IDE emulation, I don't see that happening in AHCI or RAID mode.

    yes, it happens in AHCI/RAID mode. Not in Native mode.

    Okay dude, just because the controller presents an API identical to a traditional IDE interface for the purposes of C&C and data transfers, that doesn't mean that the drives actually operate using a master/slave relationship. The whole reason for designing SATA the way it is was to get away from the master/slave relationship.

    Also, your example of using SATA ports 0/2 to achieve "master-like" connections doesn't jive with the specs that you quoted from Intel. They very clearly state that the first controller hosts FOUR ports, not TWO. Which means either the controller supports a single master with multiple slaves (unlikely), or each controller can support multiple masters as well as multiple slaves (in which case there's no reason to support slaves at all).

    hey deusefag why the fuck would intel include multiple controller for native-operation if they could magically get awsome performance and featureset from only one? Why even offer the different modes, then?

    Oh yea, LOGIC just hit me!!! THEY DON'T PERFORM THE SAME! That makes perfect sense why intel did what they did!




    And if logic and INTEL-PROVIDED documentation is not enough proof for you, then go try it. It has been demonstrated numerous times that drives on primary interfaces on seperate channels will outperform the same drives sharing the same Channel.

    Read the fucking post, fatass. Then read the info you yourself quoted from Intel. It disagrees with you. You lose. Go home.
