Prerequisites

  • Are you running the latest version?
  • Can you reproduce the problem in the debug version?

Description

MDF files created by Alcohol 120% don’t match files created by Aaru, both from dumping directly to MDS or converting an Aaruf image to MDS. The compare command doesn’t find any miscompares, so it may not be actually be an issue. Images and logs can be provided eventually if needed.

I found out it’s due to the way the format stores subchannel data, consistent hashes can’t be expected as long as subchannel data is saved in the MDF file.
