Fusion drive on MacBook Pro Mid2012

[Kayzey]

Hey all,

Trying to get a fusion drive working on my MacBook Pro. But I am running into some trouble after installing Mountain Lion.

I have a 64gb SSD and the 500g HD that came with the laptop.

I manage to create the fusion drive, install and otherwise get to the desktop. The problem happens when I run the last update from the App store. After the reboot I am stuck with two drives and none of them will boot. The recovery parition is gone.

Seems like the fusion drive breaks with the update and leaves me with two disk that aren't working. But if I boot from USB stick I still see the whole drive and everything appears to be as it should.

Any help would be great!

Alittle more info

I am using disk0s2 and disk1s2. So I am not whiping the disks, I read that this was the best way on notebooks, so I can keep the recovery parition and so on.

I am also having doubts about fusion drive...
From what I read, the Macmini 2012 comes with diskutility 13 (444). My OSx 10.8.2 has version 13 (430).

From what I read, a true Fusion Drive with smart data migration between SSD and HDD can only be created by version 444. If you use another version, you end up with a standard core storage volume...

Is this true?
Any way to install 444 on my system?

Cheers!

Well, I am writing this from the MacBook Pro with Fusion enabled. But, I am pretty sure if I run the update again, my drive will fail.

The update that breaks it is called MacBook Air and MacBook Pro update 2.0 - which should just fix graphics performance and USB issues.

After further research. It would seem that is a problem with my SSD, which is a OCZ Octane s2 media. Apparently OCZ is having problems with their firmware.
