Hello, My MacBook Air mid 2013 does not recognize the internal disk. If I plug a USB with OS-X on it, it loads up and when I run the OS install the internal SSD is not there. I’ve already tried the command + r control and it does the same. Can you help me? Update (01/18/2018) Sandisk 128GB SSD 655–1837C This is the disk i buy

it sounds like the SSD is faulty and will need to be replaced. if you go to a Apple store depending on the size it could cost more than a full logic-board, I have been switching customers to a 3rd party SSD made by OWC and they are half the price of the Apple ones. https://eshop.macsales.com/shop/ssd/owc/…
