My MacBook woke up from sleep and crashed. I had to hard reset it then it wouldn't boot up. I got the chimes but the apple logo wouldn't appear. I tried rebooting again pressing Alt to go into recovery mode and try to fix any issue with my hard drive, nothing came up. I then plugged in my time machine drive which as an OSX install partition in it, took ages (over 3 mins to load) and then my main SSD (Samsung 840, 250gb) doesn't show on the disk utility. Verbose mode doesn't respond either. I'm just letting it try to boot now to see if anything happens. WTF????
