I have had my new OWC 250 gb SSD installed in my macbook air a1730 for 2 years and out of no where one day I go to turn on my mac I get a blank grey screen with the flashing question mark file. After much trouble shooting I have found out that when I removed the drive and connect it via usb it my computer is the only way it can be found. I am able to use it and open anything on the drive when its uninstalled but when I place it back in to the computer it is unable to find it. I have performed the following tasks

  1. tried to restore from time machine but cannot locate the 250gb drive to load it too
  2. installed factory 60gb dive and everything works fine
  3. when trying to verify newer 250 ssd my computer is unable to find any problems with it so I cant repair it when in disk utility. I thought it might be my I/O cable but since my old drive when connected internally my computer works fine. I cant imagine my 250gb drive is bad because it works and performs fine… only when connected usb. I am out of options and I do not have extensive computer experience but I catch on quick. If anyone has any solutions PLEASE help me out. I need my bigger drive for work and I really do not want to buy another expensive SSD.

Hello, Try to make the updated firmware to your SSD. Look the video in down page. https://eshop.macsales.com/tech_center/O…
