Linux represents internal disks as block devices (/dev/sda, /dev/nvme0n1). The kernel’s NVMe, SCSI, and AHCI drivers bypass USB bridge chips, enabling:

This is the basis of all disk readers.
As internal drives shift to NVMe and hardware encryption (e.g., TPM, Opal), the stand-alone Linux reader key must evolve. Linux represents internal disks as block devices (
If your disk uses LUKS (Linux Unified Key Setup), the internal structure is scrambled. A standard reader sees only random noise. cryptsetup is the gateway. This is the basis of all disk readers
