I need help copying Stupid Invaders cd 3&4
 

Iam using 700meg disks but when it gets to the last 10meg or so my cd recorder makes a scraching noise and the copy finishes but you cant read the cd (its like it has run out of space or something) I noticed the original 3 &4 cds are about 695meg is this happening because its to big and my cd recorder cant handle it. (Smart & Friendly 24*4*4 ) I havent been able to get another brand of cds to try yet but cds 1 &2 are only about 670 meg each and they worked fine. If anybody can help me please do.

Thanks
