Zeality do not believe log files unless you are the one who created it, log files can be modified, results on the ACC database are static which means that it can not be modified. If you have the file, files, Disc or CD, the best way to check if it was accurately ripped without errors is by going against the same DiscID listed on the ACC database
http://www.accuraterip.com/ . Unfortunately this game is not yet listed on the ACC database. So as it stands, we can not be sure if her case is a Drive or Disc issue.
By the way, I'm glad you came by and better for had brought Radical Pan (a girl) to our VGM world.
