What were you doing when it failed?

  • I was dumping media (disk, tape, etc)...
  • I was retrieving media (disk, tape, etc) information...
  • I was scanning media (disk, tape, etc)...
  • I was retrieving device information...

Description

The Kreon commands (0xFF-prefixed) run into an issue where the commands conform to CDB6 but internal to libata, the length is expected to be CDB10. This was found during testing of a WIP commit to enable Kreon support in Redumper. Windows appears to ignore the length disparity entirely.

Exact command line used

aaru media dump /dev/sr0 ~/Downloads/xgd.iso

Expected behavior

XGD dumped without any issues unlocking and locking.

Actual behavior

Relocking behavior does not succeed.

Output of command execution with debug output enabled

N/A
