Folks, again another great update from Microsoft!! With another firmware update (many still have hope that some day will fix the surface problems). I don't know when microsoft launched it, but I did today (September 22). It broke my windows 8.1 in my surface pro 3. So now my windows doesn't startup. After several attempts to repair the initialization of the system I saw the log on "C:\Windows\System32\LogFiles\Srt" and it shows: Boot critical file C:\Windows\System32\drivers\storahci.sys is corrupt. Since I don't use system restore points, system startup repairs doesn't work and I don't want to start over on my windows again. Anyone have a idea how to fix it?
