CRC failed when extraction is at 100% (every game, not just one)

ok, so got rid of idrive (they can #### themselves), and got a buncha games, SfRush2049, Silent Scope, Sega Marine Fishing, all are selfboot, which i haven't done before. but, when i extract the .001 files, i get CRC failed at the very end of extraction, on every game, it is the same file size. also, when i run winrar, i get failures in like .011, or .020, etc. but when i run power archiver, i do not get any fails in files, just a failure at the end...i'm stumped, haven't burned a dc game in months don't really like the selfboot idea, but ah well

ps: this server goin slow?
