Not everyone has a burner that can read/write FastTrack CD protection.
So, I think this method of disc protection is quite effective. It's far more effective than using wrapped exe's which will constantly need to be re-hacked as patches for the original exe are released. Serial numbers don't work, as it only takes a single leaked number to slow sales.
If you have an old panasonic reader or writer then this may be your problem. They don't seem to like to read overburned cd's and so on. Also, you could try a lense cleaner. There maybe pet hair or dust in the drive. Don't laugh, it happens and it causes lots of read errors, that cause your drive to click away trying to read sectors.
