My question is regarding SSD sanitization.
As far as I understand, the generally accepted procedure for making SSD data unrecoverable is this:
- Full disk encryption
- Standard Format
- Second full disk encryption
- Second Format
My question is, would doing a secure erase prior to encryption affect the recoverability of the data:
- Manufacturers Secure Erase
- Full-Disk Encryption (Bitlocker)
- Manufacturers Secure Erase
- Second Full-Disk Encryption (Bitlocker)
- Manufacturers Secure Erase
If the answer is that the data is more likely to be recovered, can you please explain why encrypting the drive first would make a difference.
Thank you
