What is needed to completely clean a computer that held PHI?

• A. Delete files
• B. Reformat OS
• C. Physically destroy
• D. Have to overwrite the hard drive

Answer: (D)

To completely purge PHI from a computer, you need to sanitize the storage so that no previous data can be recovered. Simply deleting files or reformatting the OS doesn’t erase everything; remnants can remain in free space or other hidden areas and be recovered with forensic tools. Overwriting the hard drive writes new data across every sector, effectively removing traces of the original information and meeting standard data-sanitization practices. This allows the hardware to be reused or repurposed without leaving recoverable PHI behind. While physically destroying the drive guarantees no data recovery, overwriting provides a secure, practical balance for decommissioning or repurposing devices. (Note: for SSDs, some methods differ and may require secure erase commands or key destruction in addition to overwrite procedures.)
