Crashed external SSD (mini) when upgraded to 10.8.2

I really don't think that's the problem . . .but they are both 2.5's in a sata enclosure with a 3.0 USB connection cabled to Mini. My research is took me to some notes from Apple making me suspect that after the 10.8.2 upgrade that it looked at my drives as Apples New Fusion Drive. Because the Error as explained in the link here :

has very similar to what happened by losing all my data. What do you think? Thanks.

Now! Things are really weird . . . . . . I had a bran new 1T External Toshiba 5400 HD and wanted to see if it would mount with this situation. Well it did mount and Apples Disc Utility did see it and it was formated with Windows NF File System (NTFS) so I formated to Mac OS X Extended (Journald) and it took that and stayed on the desktop and functioned they way it should. . . copy files but No System Yet. Then I started to notice how Safari and everything else was Running Very Slow! I ejected the external Toshiba HD . . .rebooted and everything was back to normal speed. I still can't mount the bran New External SSD . . . Thats shows me its the OS upgrade is treating that SSD differently ( with Smash & Burn ) . . . and I still think that the upgrade to OS X 8.2 is corroupting the system OS.

DOES ANY ONE KNOW HOW I CAN GO BACK TO THE OS X .8.1 THAT SHIPPED WITH THIS MAC MINI????

Thanks for your Reply.

Thanks for your reply. I did finally get to go to restore and it took me to OSX 8.1 which it shipped with! Apples tech support told me I couldn't go backwards. . . . . And of course I did.I had to option R to get to Reastore Mountain Lion and go to another back up because I ran out of HD - SSD. It still won't recognize my New OCZ 256 with an external enclosure using USB3.0 but my next move after reading tech notes from OCZ.com is to hookup to the internal SATA and see if that does it. Will post latter. Thanks.
