I have seen a few cases of OCZ SSDs not liking AHCI. There was a case of it on here last year, guy got one for his laptop and ended up returning it.
I did do some research then, and found out the following...
Just a quick reminder for everyone. It provides no performance benefit whatsoever in a typical desktop PC. In fact having it enabled usually imposes a small performance penalty, although it too is pretty small. It is only in enterprise environments, in which access patterns are far more random than in windows, and spread out all over the surface of a drive, that any real-word benefit is derived.
That comes from the Intel forum.
When I wrote my SSD guide I did point out that before buying one you should look for reviews, and look to see the SSD you want on hardware that ghosts yours as much as possible. If not you can encounter bad stuttering problems and even crashes.
So, in summation, turn off AHCI first and run it in IDE mode. If that doesn't sort your problem then attempt flashing it.
ocz give u a flashing tool which is ment to do it for you i followed the guide they give you but it still wont update.
I've seen that too, personally. When I tried to flash TRIM firmware onto my Corsair SSD I was warned that it may not work, or, kill the drive. Corsair said if that happened to send it back to them for RMA.
And sure as eggs, it refused to flash. It found it OK, but no dice on the flash. In the end I had to unplug every other drive, run the flash from a USB stick and it finally went on. My specific chipset (an AMD) seemed to be a bit ropey for flashing it. This was the reason why Corsair held back the firmware for so long. Mostly because it was very hit and miss and they were trying to get it perfect before releasing. People kept complaining though so they finally just let people try.
