I was having issues with my work laptop so I gave it to our IT guy who sent it to Apple for repairs. When it came back he told me they had to replace the logic board (which made sense based on the problems I was having) and also the SSD (which surprised me because when I was trying to figure out what was wrong it seemed okay).
The more I think about it the more I doubt that the drive needed to be replaced. Is there any way to tell if a drive has been replaced?
My laptop is a MacBook Pro (Retina, 15-inch, Late 2013). The SSD it currently has is: APPLE SSD SM0512G.
