It seems that Linux will not see any HD on Intel's 100 Series or newer chipsets (Z170, etc.) when in RAID mode. (typically these systems have M2 NVMe devices ). This is problematic when wanting to use Linux on the system without having to disable RAID and when on their with Windows. Maybe not a linux-raid issue, but is Linux RAID issue within the kernel device support. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
