Hi no1 forest fan,
I got the same problem using Verbatim Crystal 48x media. I tried to install a game copied on Crystals and also got crc errors around 10% (can’t remember excactly).
While I was burning I noticed that my drive suddenly slowed down . This happened at the first quarter of the burning process. When the disc finished I looked at it and you were able to see two different “areas”. Before slowing down and after. I solved this problem by writting my discs at 4x, after this got no problems. This also happened with BlindWrite, Alcohol, Nero, DiscJuggler… tested it with all burning programms I got. So last but not least I think it must be the Verbatim Crystal 48x media. I bought them once got this problem, never bought them again got no problems. Hope that helps you if not perhaps someone else may help you
I looked for your burner found this at alcohol page:
WRR-52Z-can almost correctly encode EFM ( Bypass EFM Errors may need to be used depending on Safedisc Version
I think it’s not bad and not a real good burner so it’s in the middle:) but I’m not an expert in this case others know much much more about this!
Can’t realy help you with clonecd and Safedisc I’m using it very less. Prefer BlindWrite and Alcohol for Safedisc Protection. I made a working backup of tiger woods pga tour 2003 with my liteon and BlindWrite 4.5.7 you still get at VSO homepage.
