We have a bunch of HP Z240 workstations. Last week, I installed an additional Samsung SSD. Now Samsung Magician claims it can't determine the interface and AHCI mode is disabled. This would reduce performance. So I checked the BIOS settings and there's no setting for AHCI. There's a setting to enabled Intel RST, so I did. Reboot into Intel RST BIOS and while there's notting to change, it does display the settings to be SATA mode and AHCi mode.
But Magician still report it cannot determine the interface and AHCI is still disabled. Installed Intel RST in Windows including the latest driver. But that doesn't make a difference.
So how do I convince Samsung Magician the SSD is in SATA AHCI mode?
