[QUOTE=9020V;2487210]I am new to BD-R burning. I always burn DVDs at the lowest speed.
I’ve burned a few BD-R and they seem to be ok. I set IMGBURN to 1x (slowest available). It burns the BD-R at 2X since that is the lowest supported by the media. Is it better to burn at the lowest speed possible or the highest rated speed?
The BD-R media I have is RiData 4X BDR-254-RDCB15.
Also, I messed up one of these BD-Rs. I set IMGBURN to burn the disc, and I opened a program at the same time, and IMGBURN hung at 0%. I tried again, and IMGBURN said the disc was not empty and would not burn to it even though it still had 23.5 or so GB of free space. Is there any way to burn this disc or is it a coaster?[/QUOTE]
Actually, you’ve been “ruining” your DVDs by burning at an excessively slow speed for your particular burner/DVD media combination. You see, modern 16x-rated DVD media does not respond well to low-speed burns from a high-speed burner: Your slow-speed burns are much more likely to develop tons of errors and high jitter than those same discs burned at 4x speed. Burning those same discs at 8x instead of 4x will likely produce better results still. Generally speaking, with 16x-rated DVD media try to keep your set burn speed between 6x and 12x for best results.
Same thing with BD-R discs: Generally speaking, the discs should be burnt at or slightly below their rated speed (or slightly below the maximum speed supported by your burner/media combination, if your particular burner can burn faster than the media brand’s rated maximum).
As for your problem disc, it’s a coaster. In fact, we’ve been warning you against buying RiData or any other RiTEK-manufactured BD-Rs due to degradation issues with their 2x (and to a lesser extent 4x) media. Their BD department has not learned from the mistakes they had a few years ago with their G04 and G05 “8x-rated” DVD-R media, both of which have also suffered degradation issues.
