My MBA froze all of a sudden and I had to shut down by holding down the power button. When I turned it back on, it gave me the flashing question mark folder. After searching the internet for a while, I found out about recovery option w/ command+R and tried that. When I am in the recovery mode, disk utility, reinstall OSX, etc doesn't recognize my hard drive. Instead, my disk utility only shows "disk0" that's 1.29GB in size. Has anyone have this happen to their MBA? Any help would be much appreciated as my apple care ran out more than a month ago. Thank you.
