Apple is officially recalling the solid state drives in last year’s MacBook Air notebooks. The company announced in a blog post that the 64GB and 128GB flash drives used in the last generation of MacBook Airs are faulty and prone to failure.

The recall affects models that were sold between June 2012 and June 2013 and, since the laptops shipped with flash drives as the default mode of storage, it’s likely that many Apple users will be affected. Apple has released a firmware update to the Mac App Store Apple that will test whether or not your drive needs replacement. The company recommends users with faulty MacBook Airs make an appointment with an Apple Genius Bar or authorized retailer to get the drive replaced.

“If your drive is affected, we strongly recommend that you do not install any operating system updates or new applications. We also recommend backing up your data on a regular basis until you receive a replacement drive,” Apple warned.
