Secure erase for Samsung PM951 NVMe drive (2024)
Summary
This post documents a hands-on investigation into securely erasing a Samsung PM951 NVMe drive, illustrating why traditional SSD erasure methods like shred and blkdiscard can fail and exploring alternatives such as ATA security erase, nvme-cli formatting, and firmware/boot-based approaches. It chronicles experiments across USB adapters and native PCIe, detailing command failures on PM951/PM961 and collecting external references; a 2024 update adds input about a potential FLR-based workaround from Blancco guidance.
