Apple is offering a free replacement for a "very small" number of 1TB Seagate drives used in 21.5- and 27-inch iMacs sold between May and July of this year, the company notes. The drives can be replaced free of charge by bringing the unit in to an Apple Retail Store, Authorized Service Provider or other options. Apple has set up a webpage for users to enter their iMac serial number to determine if they qualify for the program.
