Apple has announced a replacement program for certain iMac 1TB hard drives.
Apple has determined that a very small number of Seagate 1TB hard drives installed in 21.5-inch and 27-inch iMac systems may fail under certain conditions. These iMac systems were sold between May 2011 and July 2011.
Any Apple Authorized Service Provider, such as Keane, will replace the hard drive in a qualifying iMac free of charge.
iMac owners will need to have the original OS installation discs that were shipped with the iMac in order to re-install the operating system, other applications, and to restore any backed up data after the hard drive is replaced.
Apple is contacting affected iMac owners who provided a valid email address during the registration process to let them know about this program. If you have not been contacted, but think you may have a 1TB Seagate hard drive in your iMac, you can enter your serial number here to see if it's part of this program.
The hard drive replacement program does not extend the standard Apple hardware warranty.
