+## Media Sanitization details
+
+The secure erasure process performed on our devices is compliant with [NIST SP 800-88r1](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-88r1.pdf) and following are the details of the implementation:
+
+|Device   |Data Erasure type   |Tool used   |Validation step   |
+|------------|------------|-------------|---------|
+|Azure Data Box        | In Public cloud: Crypto Erase <br> In Gov cloud: Crypto Erase + Disk overwrite     |ARCCONF tool | Random 10% sampling + Secondary 2% Sampling using In-house tool |
+|Azure Data Box 120 <br> Azure Data Box 525  | In Public and Gov cloud: Block Erase |ARCCONF tool | Random 10% sampling + Secondary 2% Sampling using In-house tool |
