Hard drive disposal guidelines
Per University of Montana policy, any computer or device that is leaving your department must have the hard drive disposed of properly. This can be done through either physical destruction or "wiping" the data off of the drive.
For physical destruction, a convenient option is to use the surplus process provided by Business Services. The surplus process includes hard drive destruction by default. To take advantage of this service, please fill out the form.
Another option is to "wipe" the data from the hard drive. There are a number of products available that can achieve this goal. The product must be compliant with Department of Defense policy 5220.22, have a "three-pass" process, and provide verification that data was wiped. DBAN meets these requirements and is free to use. There are a number of tutorials on how to use DBAN online.
