probs copying copies with Nero, Juggler, Clone, CDRWin etc

[Ferris]

first up, i have a Creative CDRW 8x4x32 (8435E), which copies everything (PC, PSX, Audio etc) fine except Dreamcast copies!

i have tried the following copiers with no luck

Nero 5.5 (gets to around 30% and stalls on standard DC copies, wont copy a self boot disk, just copies first few sectors and asks for a blank disk)
Clone CD 3.0.5.1 (hates my CDRW period)
CDR Win 3.8D (same problems as with Nero)
Disk Juggler 3 (same problems as with Nero & CDRWin)
Blindwrite (same problems as above, reports unreadable tracks as bad sectors)

is there a definite settings list for copying DC copies with Nero, or CDRWin? www.internetconvoy.com only seems to specify Disk Juggler.

i HAVE though managed to copy one game, "Jet Set Radio" (Jap) with no problems. Everything else won't copy. The copies i have received when i purchased my DC (pre owned) work 100% on the machine itself.

do i have a software or hardware prob?

any help is very much appreciated.

i have used nero for copying boot required dc backups,and
disk juggler for the ones with self boot,the only ones that fail to copy are the ones with errors on the copy.this may be your problem.

ckc is write. thats the same method i use and they all work fine. Jet Set Radio needs a boot disk. thats why it worked.

thanks lads for replying. i managed to sort out my prob by reading the backups to image from my DVD Rom, and burning them on the CDRW. For some reason DC backups don't like being read in my Creative CDRW.
