Hi, I was just working on my MBP (mid-2012 15" i7, non-retina) and all of a sudden it crashed. Sometimes it freezes, but this time it just logged off and restarted. Upon restarting it prompted that it had some difficulties, yadayadayada, no biggie. This time around, however, I noticed straight away that the tabs I had open in Firefox didn't load, which it normally always does. I was able to restore a previous session through a .js file (which saved me probably a day's work). Then I noticed I couldn't open Spotify. I run the system and apps of a 200gb SSD and store all my data on a internal 1.5tb (which also has my home-folder). There's some apps that also run from my HDD, but some, like Spotify, are only on my SSD. I noticed I didn't even see the SSD in my sidebar and when going to Disk Utility it also didn't show up. I've had disks corrupt on me before (no biggie, since I make regular backups), but not even showing up in Disk Utility has never happened before. Could anyone make a suggestion of what's going on here? Normally I'd probably physically dis- and reconnect the SSD, but I'm away from home so that's not an option. Thanks.
