Why not to sell you HDD or SSD with your computer

[hz211]

To securely erase an SSD, use its built-in firmware command via BIOS/UEFI or manufacturer tools (like SSD Toolbox), as it's the most effective way to reset all cells in the SSD, unlike simple formatting which leaves data recoverable; alternative methods include using encryption (like BitLocker) and then erasing, or third-party software (like CCleaner).
