I have a 2010 macbook with dual hard drives; an SSD with my OS and apps installed and its original HDD for all of my music, movies and pictures. A few moments ago I got an alert that my disk wasn't ejected properly. Nothing was plugged into the computer and then I realized my HDD was no longer showing up in finder, disk utility, etc. Unfortunately I'm a stickler for setting myself up for failure as my first instinct was to remove the drive and check for lose connections or put in an external enclosure and attempt to access it that way but my tools aren't at my house and I won't have access to them until tomorrow. I restarted twice and reset smc but nothing changed. I'm so worried that the drive has failed. Any ideas?? I'm desperate.
