一位外国的朋友向我提出这样的问题:
Hi, I noticed you like to use the bin/cue format which is something I'm a fan of. I hate iso/mp3. My question is I'm starting to dump some of my games and am doing it in bin/cue format aswell with cdrdao. Sometimes when dumping I get this error "Found 302 Q sub-channels with CRC errors." Cdrdao will still create a bin file. I will check the crc of the dump. Then I dumped it again and still got crc errors. Once I did this I checked the crc of the new file and they matched. Is this still a good dump? I want the dump to be perfect. Are the crc errors somehow fixed? Or is the bad data being dumped. Thanks in advance.

意思大概是用Cdrdao的工具做bin/cue的镜像,但出现"Found 302 Q sub-channels with CRC errors"的提示,不知道这样做出来的ISO是否good dump,如何修正??

有朋友能帮我回答这个问题吗?先谢谢,也让我学学这方面的知识!!

May be some source disks have a protect in the track. It keeped you copy the CD unlawfully . When you dumped the disk , it displayed ERROR or stopped transfer data.
But you can verify the new image by EMU program after you dump.If it`s successful ,it`s a good dump, otherwise it is bad.
