It sounds like u r trying to copy on-the-fly ie from cd reader 2 cd writer. Using CDRWIN 3.7 or above, select the icon second from left on the top row:- “Backup Disc”. This will make an image on your HDD and then it will ask u 2 insert a blank disc once the image has been recorded. Set error recovery to ignor, set jitter correction 2 auto and set subcode analysis to auto. Set retry count to 1. Set the audio and data speeds to 1 x (as this will make a better image). On the recording options make sure the speed is set to 1 x speed. IMPORTANT!!!: It is vital that u use your CD Burner to make the image not a cd-rom drive. U cannot make a bit-by-bit back up using an ordinary cd-rom drive, u must use your burner. Good Luck.
