Thank you for contacting the Intel Communities.
I would like to recommend you to create a backup of all your information and then install the latest version of Intel® RSTe.
Here you can find the driver to be downloaded: Download Intel® RSTe AHCI & SCU Software RAID driver for Windows*
Additionally, with Ctrl + I at post, you would be able to check the RAID configurations that you have in your system, to restore them or re-built them.
If you require any further information or support, do not hesitate to contact us back.
Esteban, thanks for the reply. I did try and download the driver above but it said that it was incompatible with my system. I assume that's because I have set to RST rather than RSTe in my BIOS.
So, I downloaded an old version of RST drivers (18.104.22.1686) and that installed the UI (IAStorUI) which allowed me to look at the RAID volumes. I could see that one of my drives was faulty so I've replaced it and allowed this utility to rebuild the RAID volume.
So, now everything is working fine but I do have old drivers. I'm tempted to just leave it alone but
a) will I get any benefit from upgrading to the drivers in your link above
b) if I set my BIOS to RSTe will everything still boot up okay and then I just install the drivers above?
Thanks in advance
Thank you for your answer, I am glad to hear you were able to fix the issue installing the older driver.
Now, regarding updating the driver, I would like to recommend you to contact the manufacturer of your board to check which are the supported versions and how could that change (RSTe in BIOS) affect the behavior of your system.
If any additional questions or inquiries are present, feel free to contact us back.
