MacBook Air Flash Storage Drive Replacement Program

Apple has determined that certain 64GB and 128GB flash storage drives used in the previous generation of MacBook Air systems may fail. These systems were sold between June 2012 through June 2013.
MacMedics will replace affected MacBook Air flash storage drives, free of charge.
To see if your drive may be affected, go to the Mac App Store, click on Updates, and choose the MacBook Air Flash Storage Firmware Update 1.1. The firmware update will test your drive to see if it is affected. You will be directed to Apple’s program page for the next steps if needed.
IMPORTANT: 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. Learn more about backup options
Before you bring your MacBook Air in for service, please back up your data. If you don’t have a way to backup before you visit MacMedics, we can sell you a Time Machine hard drive or a Time Capsule and backup your data for a small fee.
If you believe you have paid for a repair or replacement due to this issue, contact Apple regarding a refund.
This worldwide Apple program does not extend the standard warranty coverage of the MacBook Air.
The program covers affected MacBook Air for three years after the first retail sale of the unit. Apple will continue to evaluate service data and will provide further updates to this program as needed.
