Multi-CD games not liking next CD's

[BorgMagus]

I've burned quite a few of my games and played them through testing them, but one problem I've come across in a few of them is that when it asks to put in Disc 2, I put the disc in and it says:

error incorrect disc
please insert the correct disc

yet I can put in the scond disc and it starts up but unless the game asks me to save JUST prior to putting the next Disc in to the point where I can restore from that save on Disc two and still continue I'm stuck on the first Disc. Is there a way to put the disc in that it wil pick it up? do I need to re-burn the CD's? Like I say they'll start up and play the game fine IF I have a save on whatever disc I have in.
