Prerequisites

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

Check and fill as appropiate:

  • I was running DiscImageChef under Windows 7...
  • ...in 32-bit

Description

Comparing a DICF image with and MDS image from A120% results in a miscompare with the message "Sector 37160 has different sizes (2324 bytes in image 1, 2048 in image 2) but are otherwise identical". Where image 1 is the DICF image. The disc is CD-XA, which is probably relevant since I haven't tested those kinds of discs as thoroughly.
