The lesson
Deleting files or formatting quickly does not remove data. Use the drive's secure erase function, a full overwrite for hard drives, or reset an encrypted device so the key is destroyed.
Drives that cannot be wiped reliably should be physically destroyed, with a record kept.
Never look through or copy clients' files beyond what the job requires; record who handled devices.
Step by step
- Securely wipe a hard drive.
- Secure erase an SSD.
- Record the wipe.
- Write the data-handling policy.
