My board is an Asus P7P55D E-LX with 6xSATA 3.0 Gb/s ports configured in default IDE mode and 2xSATA 6.0 Gb/s ports supporting Marvell PCIeSATA 6Gb/s controller configured in ACHI mode. I have 1xSATA3 hdd connected to the 6Gb/s port and 1xSATA2 hdd to the 3Gb/s port. Can I connect the SATA2 hdd to the other 6Gb/s port without any worries? Is the 6.0 port backwards compatible with SATA2 drives? Thank you for your time. Happy holidays!
I'm not sure if it would work since some of the drives are in AHCI mode and others are in IDE. Why did you want to switch the port that the drive is connected to anyways? You've been helped by a 15 year old.
SATA III ports (6.0GB/s) is backwards compatible with SATA II (3.0GB/s) drives but not SATA I (1.5GB/s) drives.
SATA III drives and SATA II drives will work on both ports but in IDE mode you MAY have an issue with the SATA III drive. Use ACHI mode on both unless you are using IDE drives also and your motherboard requires this, or you are installing XP (until you load SATA XP drivers, then switch).You have to be a little bit crazy to keep you from going insane.
First thing's first, I'm not installing XP or any other OS, my m'board has 7_32-bit installed and pertaining to my inquiry, I connected the SATA2 drive to the other 6Gb/s port & so far it's working great. My SATA 2&3 hdd are connected to the 2x6Gb/s ports in ACHI mode while my 2xSATA optical drives into the 3Gb/s ports in IDE mode.
So what do you think, will this configuration hold? I'll get back if something unfavorable happens. Thanks for the reply.
I have this screen on every boot, what do you think? Posted image on: http://img836.imageshack.us/img836/...
