The following chart is a collection of disk wiping software recommended by departmental computing coordinators (DCCs) or listed on a variety of other University and security sites. Contact the IT Service CenterВ for more details and to arrange an appointment. Also, be sure to erase any stored names and numbers from phones and fax machines.Д®XTRA: CIS has a hard drive crusher used for crushing no-longer needed drives containing data covered under the Brown Restricted Information Policy. Note that when removing sensitive information, don't forget storage devices such as thumbdrives, back-up external hard drives and CDs. Overwriting replaces previously stored data on a drive or disk with a predetermined pattern of meaningless information, rendering the data unrecoverable.

Overwriting the drive's data so that it cannot be recovered.

Degaussing, or demagnetizing, applies a reverse magnetizing field to data stored on magnetic media, erasing the contents by returning the magnetic flux to a zero state.

Degaussing the drive to randomize the magnetic domains вЂ“ most likely rendering the drive unusable in the process.

Please contact ISG to schedule an appointment. Hard drives, cell phones, and PDAs that are no longer needed and contain data covered under the Brown Restricted Information Policy can be brought to the offices of ISG for crushing and disposal. For added security, the disk should be overwritten or degaussed prior to destruction. This is a good alternative for defective hard drives or those that would be too costly to repair.

Physically destroying the drive, rendering it unusable.

The three most common techniques for properly sanitizing hard drives are: See Section 5 of the document for a more detailed summary of sanitization techniques, and Appendix A for sanitization requirements for specific media/device types.

Destroy renders Target Data recovery infeasible using state of the art laboratory techniques and results in the subsequent inability to use the media for storage of data.

Purge applies physical or logical techniques that render Target Data recovery infeasible using state of the art laboratory techniques.

Clear applies logical techniques to sanitize data in all user-addressable storage locations for protection against simple non-invasive data recovery techniques typically applied through the standard Read and Write commands to the storage device, such as by rewriting with a new value or using a menu option to reset the device to the factory state (where rewriting is not supported).

The NIST Special Publication 800-88, Guidelines for Media Sanitization, provides an overview of sanitization techniques and requirements.В According to the publication,В the purpose of sanitization is 'to render access to target data (the data subject to the sanitization technique) on the media infeasible for a given level of recovery effort', and describesВ the three categories of action to be taken to sanitize media as: It also includes links to articles that provide detailed technical descriptions of what occurs during this process. This document describes some common methods and software to assist you with the sanitization process. When sensitive information is stored on the hard drive of a machine that is to be surplussed or transferred to another individual or department, it is therefore imperative that extra measures be taken to wipe clean the hard drive before the computer leaves your area of responsibility. This means that data recovery is possible using various software tools. All that deletion has done is remove the pointer to the files, with the data itself residing in unallocated space on the hard drive. These methods, however, are like sweeping something under the carpet: you may not be able to see it, but it's still there.

For the general user, the delete or format command appears to be the logical method of removing unwanted data files.
