please help.

My ssd disappeared into oblivion after  upgrading from windows 8.1 preview into windows 8.1 retail. Does anyone know how to make it appear again? I cant find it in bios and ssd firmware update tool. It happened after it restarted, after the install after the preparing your computer for first use or something like that. I think that it had something to do with an update. Im also getting a long delay before post. my mobo is a msi z77a-g45 and using a corsair force gt ssd if that helps.

ty in advance.
