Exactly. It does cut the speed in half (because it is reading and writing all of the data) but when your data is important or when the media is expensive, you don't want to throw away the disc on a bad burn like you would with a DVD that didn't verify after the burn.My understanding from specs is that it is Defect Management. I.e. the drive will write a portion of its buffer to media. Then it will checkread as long as the data is still in the buffer. If a read error occurs, then it will take relocation measures and write the content again from buffer to Spare Area. The checkread usually cuts write speed by half.
Ok, I suppose your words are a better explanation of what happened. It burned all the way up to the scratch and must have relocated the data to the spare and continued to the burn. I don't mean to say that it located the bad spot before hand. It found it when it tried to read back the scratched area and failed.This (my) understanding of MMC-5 makes me wonder why Matt's burner worked around the scratch rather than running into it and to replace the casualties by spare sectors. Did it examine the blank media for damages ? Matt: Did you scratch before or after formatting ?
