XComp/2 is a multithreaded recursive file comparison tool (as a counterpart to XCOPY) that is especially useful to compare CDs burned with the original data. Support for CRC32 and MD5 Checksums is included. Source (and WIN32 port) is included (req. IBM VisualAge C++ V3.6.5, Warp Toolkit or compatible).

Also part of that package is IsoComp/2, a utility to compare with or convert to CD-ROMs into ISO image or RSJ track image files, also supporting CRC32 and MD5 checksums. Source (and WIN32 port) is included.

You should also be able to find it on sites connected with a higher bandwidth like e.g. Hobbes - [url]
