While we had visitors earlier today, one asked if I could transfer her photos to DVD so she should free up space on her card. So I copied them to my PC and wrote them using ImgBurn. From past experience, I always check the 'Verify' option and in this case it sure prevented a problem as the verify stage failed 1/3 through the disc despite not having a coaster for quite a long time.
To my surprise, when I looked at the bottom of the disc, this is what I saw:
I'd not sure what to call these, "Rings of death"? :bigsmile:
For anyone curious, the disc is a Verbatim 16x DVD-R, MID is MCC 03RG20, written at 16x and the DVD writer is a Samsung SH-S223B.
After this, I got another disc and it wrote and verified successfully.
Has anyone else encountered ended up with a coaster with unusual rings or patterns on the recording surface? Despite numerous coasters in the past going back to the days of my first 2x SCSI CD-RW drive, I've never seen a coaster like this before.
