L0 Data Zone Capacity Miscompare when writing data to DVD+R DL with LG external

vbimport

#1

I’ve been getting that warning when burning computer data to my Verbatim DVD+R DL discs and I need insight as to what is going on under the hood.

Is this a serious error that can affect the integrity of my recorded data or is it like a cosmetic error that can happily be disregarded?

Here is the log from my last burn:

I just compared the md5 checksums of all the files written by ImgBurn to DVD+R DL and the md5 of the data on my HDD and they all matched.

Does that say anything?

is no serious error.

What counts is burn success & verify success…
