I have some old Verbatim CD-Rs made in China. I still have about half a stack left, but mostly I just burn DVDs these days, so I haven't used these in a while.
I got a new laptop recently that has a LG BU20N Blu-Ray burner. I've heard people say notebook burners are not very good, but I've gotten really good disc quality tests with that burner and TY DVD-R media.
Yesterday I tried using the laptop's BU20N burner to burn a test CD-R. The results were really bad, as you can see here:
Then I burned a test CD-R on my desktop's AD-7200A and the results were good.
So I needed to burn a ISO file onto a CD-R, so I used ImgBurn and the AD-7200A at 24X. During the verify, ImgBurn gave me a "Failed to Read Sectors 0 - 31 - Reason: No Seek Complete" warning. I ran a Nero disc quality test and it looked fine, as you can see here:
I checked the ImgBurn forum and a couple people got the exact same warning I did, and the ImgBurn author seemed to think it's a media issue. I tried burning the ISO 3 times in the AD-7200A (twice at 24X and once at 16x), and each time I got that warning message in ImgBurn, and each time the Nero disc quality test was fine. The TRT also looked fine.
You think the media is OK to use, or could the laptop BU20N drive's really bad disc quality results be telling me something that the desktop AD-7200A isn't?
