Title: ACHI mode causing problems when more than 1 HDD installed
Post by: deejayburnout on December 29, 2011, 10:09:20 pm

Hi Everyone

ACHI Reg tweak - http://forum.giga-byte.co.uk/index.php/topic,6721.0.html

Right i used the IDE registry tweak ACHI work around sucsessfully on my old GA-M68SM-SL2 mobo

When i installed my new mobo i installed Win7 with only my SSD installed as i was having problems with Win 7 installing ( but thats another story ).
ACHI mode was selected in the BIOS and all went ok. Installed in ACHI mode and i was happy.

I then plugged in my other 3 drives and started machine and now searched for on drives. Must take about 5 mins before it loads and then hangs at Verifying DMI pool data.

After several unsucessful attempts, i change the BIOS to IDE mode and machine boots ok.

No big deal, but i would like AHCI mode for my SSD.

Dark Mantis gave some advice that i have yet to try by clearing the CMOS.

Has anyone else had this problem? Any advice?

Are they all hard drives or is there an optical drive or two hidden away in there ? If so move the optical drive to another controller and set only that to IDE mode leaving the rest to AHCI.

Different motherboard but i just installed one and i set controller to AHCI then move other hard drive and sata dvd to last controller 5 and 6 and set them to ide and mine works fine. As you have more than 2 other hard drives make sure SSD is in sasa_1 and put the other drives in the last sata ports.  Worked for me but as i said different MB.

First time build: I have a new GA-X79-UD5 mobo. REV 12.  I installed one 240 Gb SSD drive via Sata cable and then installed Win 7 Pro 64 bit and it all ran just fine. I then installed two more hard drives (another 240 GB SSD and a 1TB Western Digital Sata drive, both internal).  The issue: I cannot see the new drives anywhere in Win 7 and there is no reference to them when I look in the bios setup. For some reason the system is not seeing them and i can't figure out why. I know very little about this stuff so I ma a bit over my head here. My bios Sata setting is set for AHCI (not IDE) by the way. Is there some trick to having the system find my additional HDs?

@ PJ1073R
Have you gone into Computer Management and brought them online?
