SSD works fine in SATA 2 port but when in SATA 3 port doesnt boot and says "disk

I brought a Crucial 120gb SSD and did a clean installl of Win 7 on it.
Windows didnt recognise the drive when i plugged it into a SATA 3 port so tried it in a SATA 2 and installed it via that way.
However now i want to move the SSd to the SATA 3 port but when i tried it it just comes up as "disk rread error".
I changed my bios before install to AHCI.
Any help would be appreciated.

Motherboard is -GIGABYTE GA-P67-D53-B3

  1. you can just use it in sata2, speed difference is very small. it can be a problem with the cable, motherboard or drive, you'd need to replace each one at a time to find out which.

    any special bios settings for the sata3 ports?
  2. You'll need to go the Gigabyte web site. Download and install the BIOS updates and the Driver updates. Pay particular attention to the SATA/AHCI driver update.
  3. OK thanks. I've looked on the website there is -Intel SATA Preinstall driver
    (For AHCI / RAID Mode)
    Note: Press F6 during Windows set-up to read from floppy.

    Driver update would that be the one?,and if so does it mean i have to re-install windows again?

  4. That is one of the driver updates. You do not have to reinstall Windows. Just download and install the driver update. I'm am not sure why they mentioned installing the driver from a floppy disk.
  5. I downloaded the file and extracted it but cant open any file?.
    They are .sys files?.Sorry i'm a bit of a noob to this lol

  6. It is slowly coming back to me. A long time ago if we wanted to configure a RAID array we had to copy appropriate files to a floppy disk and then use it during the Windows installation. I'm still not sure why Gigabyte listed it because hardly anyone has a floppy disk drive anymore.

    I should have gone to the Intel web site instead.

    Here is the link to the Intel driver update utility which you can try first:

    Try using it to see if Intel can detect any drivers that need to be updated.

    Next, use the Intel Chipset Identification Utility to see if it can identify which chipset you have:

    I think there were some variations in the Intel chipset. Based on the motherboard model you provided it is the one with the B3 stepping. I'm certain the utility will identify it as the Intel P67 Express Chipset.

    Next, install the latest Intel RST Driver:

    I know it says RAID but it also includes the ACHI drivers for ssd's. After downloading and installing just reboot your computer.
