After upgrading to W11, all SATA connections ceased functioning.
After upgrading to W11, all SATA connections ceased functioning.
I shared my own approach after consulting the Microsoft forum. It seems W11 behaves differently with certain drives, favoring RAID over ACHI. I changed the BIOS settings from ACHI to RAID, but it didn’t immediately restore the drives. I noticed two changes: during startup (before W11 loads), all four drives appear in the list, and the BIOS restores default settings with an option to press CTRL-C for configuration. In the Device Manager, two new RAID controllers appeared under "other devices" marked by a small yellow triangle, yet Windows couldn’t locate an updated driver. However, using the motherboard utility resolved the issue, and all drives reappeared.
