Why is my 256GB SSD not recognized in my MacBook Air?
Hi, I have a 256GB SSD that was previously working fine in a 2010 MacBook Air. I recently installed it in a 2011 MacBook Air, but it wasn't recognized in the disk utility. I installed it back in the 2010 MacBook Air, and now it isn't recognized there either. It does not show up in the list of drives. Why?? Thanks so much.
