Sometimes Blancco Drive Eraser might not detect connected hard drives even though the drives are fully functional and detected on the machine BIOS level.

SATA drives:

• This can happen if the hard drives have been set to IDE/ATA mode in BIOS.
  • SATA drives need to be set in either "AHCI" or "SATA native" mode (or similar) from BIOS/UEFI.

NVMe drives:

• Some devices require the BIOS/UEFI to be switched from RAID to AHCI mode in order to successfully present the drive to the system.
  • Usually this setting is available through "SATA Operation Mode" or "SATA Controller" (or similar) option in the BIOS.
    • If the device's controller doesn't support AHCI mode, you can remove the drive from the machine and run the erasure by connecting the drive to a supported machine.

  • This issue has been identified at least for the following devices:
