Seagate's diagnostic tool, SeaTools For Windows, kept failing a Seagate 3TB SATA drive and a Hitachi 1TB SATA drive that are connected to the Marvell Controller ports on my ASUS P8P67 EVO Motherboard. SeaTools also classified both drives under the heading of "SCSI-FC-SAS" and the other 4 internal drives I have hooked up to non-Marvell ports as "PATA-SATA".
Also, SeaTools for DOS wouldn't sense the 2 Marvell drives or the other 4 internal drives either.
Then ASUS suggested changing the setting on the Marvell controller to "IDE" instead of "AHCI" and then the 2 Marvell drives were listed under "PATA-SATA" like the other four in SeaTools for Windows. And SeaTools for Windows passed both drives. SeaTools for DOS then sensed and passed both Marvell drives, but still did not sense the other 4.
Just wondering if I should leave the Marvell Controllers set to IDE or do you think the BIOS needed flashing? And then maybe I could change them back to AHCI? Is there much difference in speed between AHCI and IDE settings?
