Computer Retirement                                                   

 

Objectives

 

*      Student will understand the importance of removing sensitive security data from hard drive before the transfer or disposal of a computer.

*      Student will be aware of erasure program options.

*      Student will be aware of alternative computer disposal options.

 

Introduction

 

Sensitive data referring to private and personal information is quickly accumulated onto a computer hard drive as we perform computer transactions, information sharing, or information transfers.  Even if we delete a page, empty the trash bin, and empty the recycle container, the hard drive still contains that retrievable data.  When a computer is transferred to another user, donated, recycled, or sent away for repair, sensitive data should be permanently overwritten or destroyed.

Review the following web sites to learn about data removal and erasure from hard disk drives, as well as PC disposal options.
