Gigabyte P55 board and SATA III drive?
Just took delivery of a new Barracuda XT 3TB SATA 6Gb/s drive, to solve my storage woes under Linux while slightly increasing my speeds over my older SATA II drives....
My board (Gigabyte P55A-UD3P) has two SATA III connectors controlled by a Marvell 9128 controller. When the new XT 3TB is plugged in to either of these, system powers up, powers down briefly (2-3 seconds), powers up, and BIOS detects the new drive as an IDE device! This even despite all SATA devices being enabled in ACHI mode in the BIOS.
However, when plugged into any of the SATA II ports, the drive is properly recognized by the BIOS as one of the SATA devices (along with the optical drive). The system powers up and stays up, instead of powering itself down and up again.
No other BIOS settings will make it work as a SATA III device, at least to the BIOS.
1) What is the reason for the strange double-boot behaviour,
2) Does anyone know why the drive is not recognized as a SATA III device when on a SATA III port?
I realize that just getting the drive to work with the SATA III ports is probably not going to make my transfers any faster, but I'd like the new drive to use this interface nonetheless, since it is one of the main features of my GIGABYTE board.
Help?
My hardware:
Gigabyte P55A-UD3P, BIOS most recent (F14)
Core i7 860
16 GB RAM (Corsair GT 2000 MHz)
Optical DVD RW SATA interface
Single ATI HD 4670 Radeon card, on the x16 PCIE bus.
Corsair HX650 PSU
Thank you in advance for any and all suggestions!
