Hi thanks for your reply flyer.
I’m more confused ever than before now.
I recall another thread by someone who experienced what I am experiencing now. He would get strange read performance from his creative cdrom reader. Put in a “good” disc, then place a liteon burned disc, and voila, no more errors. Well now this is what is happening to me.
I burn a CDR, read it in the liteon and it checks out usually 100% ok, or sometimes just one damaged sector. Put this disc into my Toshiba DVDROM and sure enough right off the bat, the cd stutters, reads at a crawl and is found to have tonnes of errors in CD Quality Test and in scandisc. Then if I place a Sony CDR which I burned ages ago (1-12X) on my 8424S Yamaha, which reads perfectly on the DVDROM, then place the liteon burned CDR which just previously came up full of errors, now reads perfectly!!! No errors in CD Quality Test and no damaged sectors in scandisc. I don’t get lucky 100% of time doing this, but the there is a consistent trend and usually I only get 1 error or only a tiny few.
Before I realized this, I had come to the conclusion that flyer had hit upon something, about the heat/cooling. It had seemed to me that if I don’t touch the CDRW for a long time, thus letting it cool, and then burn a CD, it usually came out very clean. I noticed further burns after, when the drive was warm, the burns weren’t coming out as clean, more errors and damaged sectors. Then I held a case fan near the drive to cool it and underneath and on top to try out flyers recommendation. Even after I had it thoroughly cooled and then continued to cool it while I started a burn process, the final burn at 24X on Fuji 24X media still produced some errors. So I concluded, wow this drive really has major heating problems, and I felt I had a strong case to RMA it.
But then hours later I discovered the strange observations which I stated at the beginning of this post, that all those discs that seemed to be bad, in fact read perfectly or almost perfectly when I first place and old Sony CDR burned at 8X on a yamaha 8424S. But like I mentioned, not all discs read perfectly after this initialization with the Sony, some still read terribly, but with marked improvement. Anyone have ANY??? idea what this all means?
