At about 11:45 this morning, my school MacBook shut down unexpectedly. Warily, I tried to boot it up. Nothing but an ominous clicking noise.
Apparently MacBooks had a hard drive problem that Apple knew about. Our tech staff warned us that they'd had to replace a few dozen hard drives, but that was months ago, when they were first issued. I thought I was out of the woods.
Good thing I had done my major backups early this summer.
