Body
Data sanitization is the process of irreversibly removing or destroying data stored on a memory device (hard drives, flash memory / SSDs, mobile devices, CDs, DVDs, etc.) or in hard copy form. It is vital to use the proper technique to purge all data. Our guide below is derived from NIST SP 800-88 Rev. 1 (PDF) ("Guidelines for Media Sanitization"). UT Hearl Science Center also has authoritative documents about these procedures in CS-001-Device Life Cycle Security and GP-005.01-Disposal or Destruction of Electronic & Non-Electronic Media.
Data Sanitization Guidelines
UT Health Science Center has developed a webpage to give examples of how to sanitize data and the media on which it is stored.
For other media, please refer to NIST SP 800-88 Rev. 1 ("Guidelines for Media Sanitization") and the manufacturer manuals for appropriate data sanitation techniques, commands, and tools.
Surplusing Campus Computers
Beginning January 16, 2024, disposal of all computing equipment containing electronic storage will be handled by ITS. ITS will sanitize all hard drives that are processed through this process.
This includes:
- desktop computers
- laptops
- tablets
- and removable storage such as USB drives, external hard drives, etc.
For more information or to arrange for pickup and disposal of these items, please submit a Computer Surplus service request.
All other surplus equipment should continue to go through the existing Surplus Property process.
