    Default eSata external drive on GA-EX58-UD4P using AHCI not recognized

    I bought an eSata Seagate external drive which I want to be a able to hot swap on a Windows 7 Ultimate 64bit machine with a GA-EX58-UD4P board.

    I applied the after install fix for Win 7 to enable AHCI and then set all references to AHCI in BIOS. I *think* I got all of them. need to confirm which one's are correct.

    Computer boots normally, but I can't get the drive to recognize when i plug it in. Note the eSata port is in the front of the computer case which also has ports for USB, headphone, mic, etc.

    On the board I have the following plugged in:

    SATA2_1 = HDD
    SATA2_0 = CDROM

    SATA2_3 = Front case ports
    SATA2_2 = Free

    SATA2_5 = Free
    SATA2_4 = Free

    GSATA2_1 = Free
    GSATA2_0 = Free

    Not sure what the difference is between GSATA2 and SATA2

    GSATA is enabled with additional chip, you can disable it in BIOS if not in use.
    Have you tried the eSATA bracket? How long is the total length of cables inside the case and the eSATA drive?

    I did try the bracket and same result (not recognized).

    Forgot to mention that I tried the drive on a laptop and it recognized immediately.

    I'd guess the internal cable to be less than 2ft? The drive's cable is also less than 2ft.

    SATA2_0 is recommended for your boot drive.
    Sata optical drives should be connected to the last, highest numbered sata port number, SATA2_5 for your setup.
    I use my eSata connection for my backup hard drive and use the highest numbered remaining available mobo sata port.
    Gsata ports have somewhat lower HDD/SSD performance. Gsata optical drive performance might be a bit lower than the standard Intel sata ports.
    The Gsata ports need to be enabled in the bios before you can use them.
    I'm pretty sure that the Intel AHCI drivers don't affect the Gsata ports.

    Should be OK.
    Those are not "real" sata connector, so if all fail you can buy an add on card for less han 20 USD.

    Do you have the Integrated Peripherals BIOS section to to AHCI at the top of the page?

    The lower section of that page would be the J/Micron/GSATA ports, they are slower, but also support hotswap with the correct drivers.

    Sorry, not sure what you mean. Are you talking about the BIOS settings?

    Yes, sorry I left out the word set in my first sentence :)

    I meant to say - Do you have the Integrated Peripherals BIOS section set to to AHCI at the top of the page?

    I forgot to add that when I plug in the drive with eSata cable, the external drive doesn't even power up. It does when I use the USB cable, but not the eSata cable.

    I've been assuming eSata gets power via the cable?

    Some eSATA cables have power and some do not, same applies to ports and I do not believe the eSATA ports on this board are powered.

    This might help, something about your Seagate software?
    EX58-UD4P won't boot with eSATA drives
