Custom Erase is a secure file deletion algorithm designed to permanently erase data on traditional HDDs by overwriting file contents using advanced patterns.
On SSDs, overwrite techniques are less effective due to internal block remapping and wear leveling. For guaranteed erasure, hardware-based Secure Erase or vendor-specific tools are recommended. These limitations on SSDs are inherent to the hardware architecture and affect all overwrite-based erasure tools — not just Custom Erase. For critical sanitization, refer to NIST 800-88 guidelines or manufacturer tools supporting ATA Secure Erase or NVMe Format NVM commands..
