Issue

• hwcert-client: Why is my BLURAY test failing?
• The hwcert-client test fails. Command dvd+rw-mediainfo /dev/sr0 outputs this:

kernel: sr0: CDROM (ioctl) error, command: Read TOC/PMA/ATIP 43 00 00 00 00 00 00 00 0c 00
kernel: sr: Sense Key : Medium Error [deferred] 
kernel: sr: Add. Sense: Medium format corrupted

• I see this:
