Sarah was working at home on her computer and just completed a large presentation for work using PowerPoint and Word documents. She saved the information to her hard disk, just before a lightning strike hit near her house and her computer stopped working. Frustrated, she took the computer to work the next day and had her network IT person look at it. She was told that only the master boot record had been corrupted, and the tech was able to restore the MBR and get all her information accessible again.

a. What did the IT tech do to recover the MBR?

b. In the future, what should Sarah do with any information stored on her computer hard drive?
