Need CD-RW recovery



Bought a used pc. Was told after the fact someone tried an upgrade of CDRWIN & used an bad crack on it; now ive got 4 CD-RW that wont be recognized by nero, cdrwin, etc. Tried full erase, but cd is ejected before erasing starts. I heard CDRWIN did this as anti-piracy protection. Is there any way to recover these CD-RW's? TIA
