Disk scrubbing is a process in which a hard drive is overwritten with useless data (typically a single number) before the hard drive is disposed of. State Law requires that University-owned hard drives and similar devices be scrubbed of data before disposal. To protect personal information privately owned computers and other devices that store data should be wiped or destroyed as well.
This document explains the basics of disk scrubbing and provides links to current university policies and frequently asked questions.
