Hello, I'm a pretty solid IT guy and am having trouble figuring this out...here is my situation. 2011 2.0 i7 running 500gb SSD in with a 1TB spinner in the DVD slot. OSX (mt. lion) just gave me an update for thunderbolt...which I obliged. My Crucial M4 (500gb) wouldn't boot. I was able to see through disk utility that the disk was not recognized now for whatever reason. Slapped in a OCZ Agility3 (256gb) that used to work fine...it's not recognized either. Then I put in an old 5400rpm spinner and it showed right up...I was able to restore. Now I'm trying to view both the two SSDs (Crucial and OCZ) via firewire in an external case and they still don't show up. Then I tried a USB case (non powered) and they don't show up but a spinner does. 1. Is anyone else reporting issues with SSD not working or getting bricked? 2. Does anyone have an idea here or a better way to troubleshoot if I'm off base? No I don't know what firmware these drives have...since they worked I didn't bother as I've had bad experience with SSD firmware upgrades...and now this firmware upgrade for thunderbolt!
