I changed my original HDD for a SDD earlier this year and I just got one more SSD for my MBP 13 (2012) that I used to replace DVD drive. I'm using Mountain Lion.

The SSD looks to be recognized allright, but I can't format it.

Then I removed the main drive and tried the new one as the main drive and did the boot using a USB drive with MAC OS and everyhing worked as it should (like I just had one drive). However when I bring the first drive back together with the second they both show up but I can't use it. Seems like I have no permission, but when I look at it's properties it says I can read and write to it.

Any ideas?

Thanks a lot!

Hope you didn't mess with flat cable while changed HD to SSD. That seems to be the same issue I had few months ago.

Can you expand on this? Do you mean that the cable was damaged, or loosened, or misconfigured, and were you able to resolve it at the time? – Jonathan Garber Dec 18 '12 at 17:29

I think I found the problem...

But it is strange... the SSD is recognised as 6G, but doesn't work well...

I'm trying install the SSD OCZ Vertex 4, I'm using OCZ Vertex 3 in the main drive.
