Luckily KF games have a single data track so it's fairly easy.
Get a copy of ISOBuster, insert original game disk in PC's drive (won't work with a copied CDR disk).
For CD:
Right click on 'Track 01' and select 'Extract Raw data (2352...)".
For DVD:
Right click on 'Track 01' and select 'Extract user data...'
When finished, rename track01 and do the above steps a second time. You have to do it twice because CD drives try to fix read errors by 'guessing' what the data is. If a disk has read errors (from scratches etc), its CRC will come out differently each time you dump it.
Lastly, use any CRC32 tool like HashCalc to measure both Track 01 images; if both have the same CRC, there's a very good chance the disk image is perfect.
When two disk images have identical CRCs, they are byte for byte identical.
