AHCI port hang on bootup

sas.wlv · 3 May 2010 at 15:09

OK, I've set my bios from IDE to AHCI mode but when it comes to starting up the computer it gets stuck on the line 'Auto-Detecting AHCI Port 1' which happens to be where my Intel 160gb SSD is installed.

If I take out the Intel drive I have no problem getting the pc past the boot screen, but as soon as the drive is installed (on no matter which socket) it will get stuck on the auto-detecting port (be it 1,2,3,4 etc).

In IDE mode I have no problems, only when switching to AHCI.

Anyone else had this problem or got some ideas of how to fix it?

Motherboard: Asus Maximus Formula
SSD: Intel X-25 160gb G2

Is there a BIOS update for your motherboard available?

already installed the latest according to the asus website (1403).

Also I have one of the 40gb intel ssds installed which doesnt seem to have this problem.

What about the SSD then?

latest firmware as well, the fact that it works fine in IDE suggests theres nothing wrong with the drive itself tho?

would it be worth using HDDErase on it?

You may have found a compatibility issue between the board and SSD. I'd try the ASUS forums or contact them via mail/support system to see if they are aware of this. I'm not sure what else the problem could be. The board isn't that new is it?

hdderase fixed the problem, can now boot with ahci no problems

Glad you sorted it.

You appear to have the same problem as I posted Here, longer thread Here on that problem...

Problem seems to be (from Post 45):

...some form of incompatible partition data on the drive
