Does your 2006 or 2007-built MacBook have hard drive issues? It might be covered under a new repair extension program. Apple has determined that a small percentage of hard drives used in MacBooks sold between May 2006 and December 2007 may fail prematurely. The only model known to be affected is the 13-inch black and white MacBook with processor speeds of 1.83GHz, 2GHz, or 2.16GHz, and hard drive capacities of 60GB, 80GB, 100GB, 120GB, or 160GB.

If your 13-inch MacBook was purchased in that timeframe and shows a flashing question mark on the screen, Cupertino wants to hear from you. You can bring the system to Apple or an Apple Authorized Service Provider to determine if the drive is eligible for free replacement. The company is also offering some customers reimbursements for out-of-warranty repairs. Coverage is only extended for three years from the original purchase date or until August 15, 2010 (whichever is longer), so don't put it off.
