There comes a time in the lap top life time when you will be looking to replace that hard drive of yours. Overtime the hard drive could wear out and you will start experiencing problems like crashing and blue screens. Let me tell you, no one wants to go trough the aggravation of recovering a lost hard drive as it is a painful and long process. It is highly recommended to change your hard drives every two to three years or at least reload your OS for a quicker response from opening and operating programs.
