Apple wants to replace some hard drives in a number of its iMac models for free, due to a failure issue reported in some of those systems.

If you own a 27-inch version of the iMac with a roomy 3TB hard drive, you might be able to get a free replacement for that drive. The company has quietly started a replacement program for those systems.

Here are the details, as revealed on Apple's website:

Apple has determined that a very small number of 3TB hard drives used in 27-inch iMac systems, may fail under certain conditions. These systems were sold between December 2012 and September 2013. 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 an iMac that fit the requirements of the replacement program but have not gotten an email, you can go to Apple's site and enter the PC's serial number to see if it is eligible. Apple adds that if you have an iMac that fits the replacement program, and have already paid for a hard drive repair or replacement before now, you may be able to get a refund.
