    Intel RST driver concern

    An Intel RST driver already downloaded through WU on my desktop with a Z370 chipset.

    Device Manager nags with a pop up message that Intel 300 Series Chipset SATA AHCI Controller is ready to install the driver

    A probable cause for raised concern was found on Win-Raid :

    Attachment 331724

    this page was where the screenshot was taken on Win-Raid - Section I, download links from the v17 platform

    I'm certain the driver will install in AHCI mode without issues
    Intel RST vs Windows AHCI drivers. (post #5)

    But its the reports of the drivers overtaking the management of the M.2 PCLe NVMe on the only system drive available that raises concern. I don't even know for sure what "completely overtaking" means. How great of a concern is that?

    . . . aside from creating a system restore point, anyone have any suggestions?

    Ok. So within about maybe an hour and a half, the warning was taken down which I captured in a screen shot.
    The link I posted to Win-Raid will take you to the page. I know it was the same page because I had it bookmarked before I saved a screen shot. I'm still searching through the Win-Raid forum for posts #2200 up by 100PIER and Frame for an explanation.

    Odd... now I'm curious why the warning was posted in the first place

    Actually, they only moved the warning to the "important remarks" section.
    It's just as well anyway because this wasn't the proper venue to ask here
    Hopefully he can clue me in on his forum with some details.

    Regarding reports of incidents of "complete overtake" of the management of all M.2 PCLe connected non-RAIDed NVMe SSD's and v17 and v18 platform Intel RST drivers as noted under the 'important remarks'.

    The meaning of the warning was confirmed as being taken out of context and mis-interpreted and is not to be implied to be all inclusive of all M.2 PCLe connected non-RAIDed NVMe SSD's and their respective manufacturer drivers, but rather to M.2 PCLe connected NVMe SSD's and Samsung drivers.

    If you are not using neither Intel's Optane nor Intel's fake RAID, I would go with MS standard AHCI driver for all SATA controllers.

    I don't have Optane
    I remember reading in another thread where you suggested the MS standard AHCI driver.
    I can't remember though the reason ...if it was something about stability. I just don't remember

    I changed to AHCI mode about 18 mos ago. All I did was change the SATA controller mode in the BIOS (in safe mode without having to re-install Windows)
    The SATA Controller mode came factory pre-configured in the BIOS in Raid On mode. From my understanding, in Raid ON mode, you put the NVMe drivers behind the Intel RST controller, and by design the software canít see past the IRST controller

    The change to AHCI automatically set up the install of Intel's 300 Series Chipset SATA AHCI controller.

    To be honest, the reason I haven't changed it is because I'm not certain how to go about it. If I had to guess, there's more to uninstalling the Intel 300 Series AHCI in Device Manager by clicking uninstall ... or does the MS Standard AHCI controller become the default after uninstalling Intel's ?
    never mind. a search showed how to pick from a list of device drivers to replace the Intel driver

    Also, when I did the SATA mode change in the BIOS, the change replaced the Chipset SATA /PCIe RST Premium Controller with the Microsoft Standard NVM Express Controller.
