Software Wiping

Software wiping uses tools like DBAN or Blancco to overwrite drives to NIST 800-88 standard, making original data unrecoverable. The drive remains usable with high residual value; suitable for general commercial and low-classification data.

Physical Destruction

Physical destruction uses drilling, shredding or degaussing to destroy platters — data is unrecoverable and the drive is scrapped. Suitable for high-classification media (finance, government, core R&D). Chun Yam provides full video and Data Destruction Certificates.
