Why does my laptop have problems booting up sometimes?

Episode 1190 (33:00)

Steve from Hermosa Beach, CA

Steve has a Lenovo X1 that has intermittent boot up problems. Leo says that hard drives can fail or have "flakey spots" with corrupted areas. That makes them unreliable. He can use SpinRite to mark off the unreliable sectors and move the data to a better spot. Or he can just replace the hard drive.
