SSD will not show up after installing
I bought the second HD kit just after purchasing the Mac in 2011 and installed a 1TB second drive. Ended up removing that drive and the stock drive as well and installing an 80GB SDD that worked perfectly until I ran out of space due to the data files for a massive iTunes library stored on a 4TB external drive. I installed a second 80GB SSD as a user drive to solve the space problem and used the drive utility to combine the original 80GB back into one partition. When I installed the OS the new drive would not show up in any utility or the terminal. I finally installed the OS on the new SSD and both drives were available, however the online reinstall would only install lion not mountain lion. When I upgraded to mountain lion I would get a grey screen only able to safe boot. On safe boot all drives are available. I switched back to installing the OS on the original drive but again lost the new SDD.
Sorry for the long winded description as I saw no other problem here that exactly matched this.
Also the 2 SDD and one external HDD is the configuration I plan to use so please no answers suggesting different drives or configurations unless you know my configuration will not work.

Mountain Lion offered Fusion Drive services, is it possible the OS installer is confused as it was expecting an HD - SSD Vs SSD - SSD setup.

I have read a dozen articles on replacing the internal HD with two SSD's. It appears there is a specific procedure but no one says why you need to follow them. I may have found out why. Is it that the Mac was not built with two SSD's and having issues with recognizing them? How do I fix my problem if that is the case?

I do think the OS installer is the issue here as I'm sure Apple never thought to test it with a double SSD setup. You really need to talk with a Genius at an Apple Store to push this up the food chain (they won't charge you for this).

Yesterday I had a chance to speak with our corporate Apple rep. He'll put in a call to his advanced support contact in Apple HQ. I'll let you know what I find out.
