By ‘blocked’ CD you mean copy-protected ? Well you can be sure all new released games will be protected. The most common new protection out there is SafeDisc 2. For more info on this protection read:
SafeDisc 2 explained and defeated.
If you want to know what protection was used on your disc I would suggest using a copy-protection scanner like ClonyXL (for downloads check www.ghostcdr.com). This program will scan the disc and tell you what protection was used. It will even pass the correct settings to CloneCD for you.
The games you mention have the SafeDisc (FIFA 2001) and the SafeDisc 2 (FIFA 2002) protection I believe. The normal SafeDisc protection can be copied by CloneCD by enabling the Fast Error Skip setting. The SafeDisc 2 protection uses the same setting but you need a compatible writer to do the job. Read the first article I mentioned and this one for more info on the new CloneCD options.
