The 64GB and 128GB drives were used in systems sold between June 2012 and June 2013, and Apple says all those affected can get a free replacement at an Apple retail store or an Apple authorized service provider.
Apple "also recommends backing up your data on a regular basis until you receive a replacement drive."
In addition, if your drive has failed and you had to pay for a replacement, Apple will refund you.
If you think you may be affected, check Apple's support page here.
