problem with copying multiple psx disks

[grasshopper]

Please help a newbie,
Am having problems copying psx games with multiple disks.
1) Syphon Filter 2 the first disk plays fine but when prompted to place the second disk (the copied one) an error message shows up. But after I place the original in and save it one time, I can use my back-up disk without any problem.
2) Fear effect 2 does the same thing, yet Gran Turismo 2 back-ups work without a problem.

*both Fear effect 2 and Syphon fiter originals are NSTC and are without copyprotection (at least that I can find)

have tried both clonecd and cdrwin for copies without success. Thanks in advance ---grasshopper
