Bug in Freeboot \"Wipe disk...\"

Welcome to the forum!
Please just do not throw rags, because after reading dozens of topics I never found the answer...
Bought Xbox 360 Slim 250 gb with it, installed Freeboot and 12 games. All games are good, without jambs, GTA has just rode. Decided to put a fresh, pumped games, threw the stick, got rid as it should be hdd1. Rayman comes to rules, 6 other games give a stupid mistake Wipe disc with cloth and restart the console...
Just please, tell me what the problem??
