Disposal

Purchasing Policy P-160, entitled "Disposal of University Surplus Assets", outlines the responsibility of the user/department for the proper removal of all university and/or personal files from the hard disks before sale, transfer or disposal of surplus computer equipment. The policy, available at the Department of Purchasing Resources website strongly recommends and encourages owners to contact UTS for assistance to ensure that these files are properly removed.

It is not enough to delete files from the hard drive of a computer that is being transferred to another person. When you delete a file, the information is not actually erased from the hard drive, but rather the entry pointing to the file is removed from the index. Even writing zeroes over the entire hard drive is not sufficient to completely remove traces of a file. Technically, a zero written over top of a 0 is distinguishable from a zero written over top of a 1. There are numerous companies offering data recovery services and/or utility programs that have the ability to recover data from files that have been deleted or from disks that have been damaged in some way. Someone with the knowledge and the incentive could retrieve the information.

Where there is sensitive data on the hard drive, some conservative security experts suggest that hard drives should be destroyed rather than risk the contents being read. Others offer various suggestions as to the number of passes that writing random patterns of 0's and 1's would sanitize a disk for all practical purposes. Of course, this process can take hours. Client Services offers a service to properly clean a hard disk before disposal or transfer. For more information contact the UTS Service Desk.
