iMac 1TB Seagate Hard Drive Replacement Program

Apple has determined that a very small number of Seagate 1TB hard drives used in 21.5-inch and 27-inch iMac systems, may fail under certain conditions. These systems were sold between May 2011 and July 2011.

Apple or an Apple Authorized Service Provider (AASP) will replace affected hard drives free of charge.

Apple is contacting affected iMac owners who provided a valid email address during the product registration process to let them know about this program. If you have not been contacted, but think you have a 1TB Seagate hard drive, you can enter your [on the page link above] to see if it's part of this program.

Finding your iMac serial number is easy. See how.

Replacement Process If your iMac has an affected hard drive, please choose one of the options below to get it replaced:

Apple Retail Store - Set up an appointment with a Genius. Apple Authorized Service Provider - Find one here. Apple Technical Support - Contact us for local service options.

Apple recommends replacing affected hard drives as soon as possible. Before you go in for service, please back up your data. Learn more about backup options.

Additional Information You will need to have the original OS installation discs that were shipped with your product in order to re-install your operating system, other applications and any backed up data after your hard drive is replaced.

This worldwide Apple program does not extend the standard warranty coverage of the iMac.

Apple will replace affected Seagate hard drives, free of charge, until July 23rd, 2012. Apple will continue to evaluate service data and will provide further extensions to this program as needed.
