Description

When dumping a specific CD, verify says that the output image has 3 unknown sectors. This dump matches a dump made by DIC in all but those 3 sectors, where the differing sectors are 0'd out in the DIC dump, but contain some kind of data in the Aaru dump.

Exact command line used:

aaru i verify .\DAG_DEMO.aaruf

Output of command execution with debug output enabled

aaru 5.2.99.3380-alpha+10d286ad built by DESKTOP-8B4K7NM in Debug
