After discovering that some of the 1TB hard drives used in some iMac systems could fail under certain conditions, Apple has started a replacement program. The replacement program affects 21.5-inch and 27-inch iMac systems that were sold between May 2011 and July 2011. For users who are affected by this recall, Apple or an Apple Authorized Service Provider will replace the drive without cost to the user.
Apple is in the process of contacting affected iMac owners who provided a valid email address during the product registration process. If you think your system might be included in this replacement program, you can visit Apple's drive replacement program Web page to find out more and see if your iMac's serial number is one of the ones affected.
