According to Tech Power UP, Gigabyte recently released a Windows tool that allows users to change the SATA controller mode without digging into the BIOS. The SATA controller mode relates to how the controller on the motherboard or add-on card communicates with the hard drive or SSD. Users will be able to choose from legacy IDE, AHCI, and RAID modes. From the brightly colored Windows tool, users can change the setting accordingly. The utility will then write the setting to the CMOS and prompt the user to reboot the computer so that the change can take effect.
The tool will work with any Gigabyte motherboards with the Intel H61, H67, P67, or Z68 chipsets. Further, the utility will run on both 32 bit and 64 bit versions of Windows Vista and Windows 7 operating systems. It is available to download from here. The package comes as a zip file containing an executable that does not need to be installed, which is a welcome touch.
While the Gigabyte Disk Mode Switch tool will make changing the setting easier than digging through the BIOS, it effectively accomplishes the same thing. What this means from a practical standpoint is that the Windows tool for changing the SATA mode suffers from the same issues that changing it in the BIOS does; mainly that the (Windows) operating system does not like such drastic changes and the user may encounter problems with Windows recognizing the drive and/or assigning the proper drivers. This is an issue primarily when changing the SATA mode of the drive that the operating system is installed on. While there are some registry tweaks that promise to help smooth the process, it is generally recommend to ensure the proper SATA mode is set before installing Windows onto the drive. Therefore, this tool’s usefulness is somewhat questionable.
Have you encountered any issues in changing the SATA mode post-install? Is this gigabyte tool useful or just another piece of manufacturer "helpware" that DIYers will never use?
