This is a bug I think with the new mountain lion update for macbook pro and airs 2.0...and on top of that this update also disables TRIM for 3rd party SSDs and won't allow it to be activated via command line...
When I go to About This Mac and then select Storage, my SSD is listed as something weird...
"256 GB Solid State Sata - -"
Does anyone have this issue who has a samsung 830 SSD?
