Sometimes Blancco Drive Eraser / Blancco 5 might not be detect connected hard drives (one or more).
For 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.
For 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.
- 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.
