Windows 7 - SATA that support AHCI and RAID mode only

I have an Asus M4N78 PRO.

There are 6 Sata connectors but 2 support AHCI and RAID mode only. (4 red and 2 black)

I have 3 harddrives and 1 DVD connected in the 4 red ports.

Maybe I'm going to buy a SSD to speed up my PC Is it possible to use one of the black sata ports if I enable AHCI. (I don't want RAID, just want to use it like the others SATA ports).

Then should I put my DVD or a harddrive in the black port?

If you enable AHCI, I suppose that SATA ports 5 and 6 will behave like the other four SATA ports. I see no indication in the M4N78 PRO manual that ports 5 and 6 are on a third-party controller.

On my own Asus motherboard, I'm using AHCI mode. An SSD, a HD, and two optical drives (all SATA) work without problems.

I don't know how easy it is to switch to AHCI mode without re-installing windows with your nVidia chipset. It's not difficult with Microsoft drivers:

Error message when you start a Windows 7 or Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"

Thank you!

If I buy a SSD I have to re-install windows and then then I guess there will be no problem?

Just to switch to AHCI in BIOS and re-install windows?

If I don't re-install windows I'll try this guide:
AHCI : Enable in Windows 7 / Vista

I have Windows 7 x64.

Right. No problem.

If you try switching to AHCI without a re-install, let us know how it goes.

I bought a SSD disk and switched to AHCI in BIOS then I installed Windows 7 Ultimate. But now I can't see one of my old harddrives

In Disk manegement I can see the disk and I choose Convert to Dynamic disc. But I still can't see it in My computer.

I've installed the motherboard and graphics drivers. Now I'm installing all recommended Windows updates. Hope it helps.

I have moved all harddrives to differnet SATA ports. The SSD is in port 5.

Any suggestions if it doesn't help with windows updates?

Hi,

Just to check: this disk in Computer Management, does it have a drive letter?

No..and the updates doesn't help.

Are you able to assign a drive letter to it?

Oh, thanks It was easy Maybe a conflict...

I didn't have to Convert to a dynamic disk. But I wouldn't install OS on it anyway so it's fine

No worries mate
